Hexadecimal values are indicated by a numerical or alpha-numerical value followed by the letter
“h.” Binary values are indicated by a value of ones and zeros followed by the letter “b.”
Numerical values that have no succeeding letter can be assumed to be decimal unless otherwise
stated.
1.5.2 RANGES
Ranges or limits for a parameter are shown using the following methods:
Example A:
Example B:
Bits <7..4> = bits 7, 6, 5, and 4.
IRQ3-7, 9 = IRQ signals 3 through 7, and IRQ signal 9
1.5.3 REGISTER NOTATION AND USAGE
This guide uses standard Intel naming conventions in discussing the microprocessor’s (CPU)
internal registers. Registers that are accessed through programmable I/O using an indexing
scheme are indicated using the following format:

Figure 3–2. AMD Athlon XP Processor Internal Architecture and Key Statistics.
The Athlon XP processor uses 0.13 micron technology that yields lower power requirements for a
given processing speed. The system board supports the unit types listed in Figure 3-2.
The Athlon XP processor uses a 133-MHz (on D315 systems) or 166-MHz (on d325 systems)
clock signal for the front side bus. Data transfers are qualified on the both the rising and falling
edge of the clock cycle, effectively doubling the data throughput rate to 266- and 333-MHz.

Chapter 3 Processor/Memory Subsystem
The AMD Athlon XP processor is compatible with software written for Athlon 4, Duron, and
most other x86 processors, but will require the latest versions of operating system software to take
advantage of the specific features and functions.
3.2.2 PROCESSOR UPGRADING
This system uses the Socket A mounting socket. A replacement processor must use the same type
heat sink (passive or fan cooled) as the original to ensure proper cooling.
CAUTION: The D315 model supports processor speeds up to 2.0 gigahertz. The d325
model supports processor speeds up to 2.3 GHz. Using a processor that exceeds a
particular model’s capability may result in equipment failure and/or damage.
!
NOTE: These systems ship with Athlon XP processors but do support Duron processors
as well.
The heat sink is specially designed provide maximum heat transfer from the processor component.
CAUTION: Attachment of the heat sink to the processor is critical on these systems.
Improper attachment of the heat sink will likely result in a thermal condition.
Although the system is designed to detect thermal conditions and automatically shut
down, such a condition could still result in damage to the processor component. Refer to
the applicable Service Reference Guide for processor installation instructions.

MEMORY SUBSYSTEM
These systems provide two 184-pin DIMM sockets that accept DDR DIMMs. The D315 models
ship with PC2100 DIMMs while the d325 models ship with PC2700 DIMMs.
NOTE: The DDR SDRAM DIMM "PCxxxx" reference designates bus bandwidth (i.e.,
a PC2100 DIMM, operating at a 266-MHz effective speed, provides a throughput of
2100 MBps (8 bytes × 266 MHz)).
These systems support DIMMs with the following specifications:
♦
♦
♦
Unbuffered, non-ECC with SPD rev. 1.0
CL (CAS latency) = 2, 2.5, or 3
Single or double-sided
The following table lists the differences in DIMM support between the D315 and the D325
models:
D315
PC2100 (266-MHz)
512 Mb
d325
PC2700 (333-MHz)
1024 Mb
DIMM Type (max speed)
Highest technology level supported
Maximum amount supported
1 GB
2 GB
The SPD format as supported in this system (SPD rev. 1) is shown in Table 3-1. All DIMMs must
yield a value of 07h (indicating DDR memory) in SPD byte 02 (i.e., only DDR DIMMs are
supported in these systems).
The memory subsystem is controlled by the memory controller integrated into the IGP component
of the NVidia NForce chipset. The D315 model supports a 64-bit wide memory array with a
maximum capacity of up to 1-GB using 512-Mb memory technology. The d325 model provides
(with two DIMMs installed) a 128-bit wide memory array with a maximum capacity of 2 GB
using 1-Mb memory technology.
NOTE: Non-supported DIMMs will not be recognized by the BIOS during the boot
sequence and therefore not be used.

PCI BUS OVERVIEW
NOTE: This section describes the PCI bus in general and highlights bus
implementation in this particular system. For detailed information regarding PCI bus
operation, refer to the PCI Local Bus Specification Revision 2.2.
These systems implement a 32-bit Peripheral Component Interconnect (PCI) bus (spec. 2.2)
operating at 33 MHz. The PCI bus handles address/data transfers through the identification of
devices and functions on the bus. A device is typically defined as a component or slot that resides
on the PCI bus (although some components such as the IGP and MCP or MCP-2 are organized as
multiple devices). A function is defined as the end source or target of the bus transaction. A
device may contain one or more functions.
In the standard configuration these systems use a hierarchy of three PCI buses (Figure 4-1). The
PCI bus #0 is internal to the chipset components and is not physically accessible. The AGP bus
that services the AGP slot is designated as PCI bus #1. All PCI slots reside on PCI bus #2.

4.2.1 PCI BUS TRANSACTIONS
The PCI bus consists of a 32-bit path (AD31-00 lines) that uses a multiplexed scheme for
handling both address and data transfers. A bus transaction consists of an address cycle and one
or more data cycles, with each cycle requiring a clock (PCICLK) cycle. High performance is
realized during burst modes in which a transaction with contiguous memory locations requires
that only one address cycle be conducted and subsequent data cycles are completed using auto-
incremented addressing. Four types of address cycles can take place on the PCI bus; I/O, memory,
configuration, and special. Address decoding is distributed (left up to each device on the PCI bus).
4.2.1.1 I/O and Memory Cycles
For I/O and memory cycles, a standard 32-bit address decode (AD31..0) for byte-level addressing
is handled by the appropriate PCI device. For memory addressing, PCI devices decode the
AD31..2 lines for dword-level addressing and check the AD1,0 lines for burst (linear-
incrementing) mode. In burst mode, subsequent data phases are conducted a dword at a time with
addressing assumed to increment accordingly (four bytes at a time).
4.2.1.2 Configuration Cycles
Devices on the PCI bus must comply with PCI protocol that allows configuration of that device by
software. In this system, configuration mechanism #1 (as described in the PCI Local Bus
specification Rev. 2.2) is employed. This method uses two 32-bit registers for initiating a
configuration cycle for accessing the configuration space of a PCI device. The configuration
address register (CONFIG_ADDRESS) at 0CF8h holds a value that specifies the PCI bus, PCI
device, and specific register to be accessed. The configuration data register (CONFIG_DATA) at
0CFCh contains the configuration data.

Chapter 4 System Support
Two types of configuration cycles are used. A Type 0 (zero) cycle is targeted to a device on the
PCI bus on which the cycle is running. A Type 1 cycle is targeted to a device on a downstream
PCI bus as identified by bus number bits <23..16>. Figure 4-2 shows the configuration cycle
format and how the loading of 0CF8h results in a Type 0 configuration cycle on the PCI bus. The
Device Number (bits <15..11> determines which one of the AD31..11 lines is to be asserted high
for the IDSEL signal, which acts as a “chip select” function for the PCI device to be configured.
The function number (CF8h, bits <10..8>) is used to select a particular function within a PCI
component.

4.2.2 PCI BUS MASTER ARBITRATION
The PCI bus supports a bus master/target arbitration scheme. A bus master is a device that has
been granted control of the bus for the purpose of initiating a transaction. A target is a device that
is the recipient of a transaction. The Request (REQ), Grant (GNT), and FRAME signals are used
by PCI bus masters for gaining access to the PCI bus. When a PCI device needs access to the PCI
bus (and does not already own it), the PCI device asserts its REQn signal to the PCI bus arbiter (a
function of the system controller component). If the bus is available, the arbiter asserts the GNTn
signal to the requesting device, which then asserts FRAME and conducts the address phase of the
transaction with a target. If the PCI device already owns the bus, a request is not needed and the
device can simply assert FRAME and conduct the transaction. Table 4-2 shows the grant and
request signals assignments for the devices on the PCI bus.

PCI bus arbitration is based on a round-robin scheme that complies with the fairness algorithm
specified by the PCI specification. The bus parking policy allows for the current PCI bus owner
(excepting the PCI/ISA bridge) to maintain ownership of the bus as long as no request is asserted
by another agent. Note that most CPU-to-DRAM and AGP-to-DRAM accesses can occur
concurrently with PCI traffic, therefore reducing the need for the Host/PCI bridge to compete for
PCI bus ownership.

4.2.3 OPTION ROM MAPPING
During POST, the PCI bus is scanned for devices that contain their own specific firmware in
ROM. Such option ROM data, if detected, is loaded into system memory’s DOS compatibility
area (refer to the system memory map shown in chapter 3).
4.2.4 PCI INTERRUPTS
Eight interrupt signals (INTA- thru INTD-) are available for use by PCI devices. These signals
may be generated by on-board PCI devices or by devices installed in the PCI slots. For more

4.2.5 PCI POWER MANAGEMENT SUPPORT
This system complies with the PCI Power Management Interface Specification (rev 1.0). The PCI
Power Management Enable (PME-) signal is supported by the chipset and allows compliant PCI
and AGP peripherals to initiate the power management routine.
4.2.6 PCI SUB-BUSSES
The chipset implements two data busses that are supplementary in operation to the PCI bus:
4.2.6.1 Hyper Transfer Link Bus
The NVidia NForce chipset implements a Hyper Transfer Link bus between the IGP and the MCP
components. This bus operates at 800 MHz and is transparent to software and not accessible for
expansion purposes.
4.2.6.2 LPC Bus
The MCP and MCP-2 implements a Low Pin Count (LPC) bus for handling transactions to and
from the LPC47B367 Super I/O Controller as well as the BIOS ROM. The LPC bus transfers data
a nibble (4 bits) at a time at a 33-MHz and is generally transparent in operation. The only
consideration required of the LPC bus is during the configuration of DMA channel modes (see
section 4.4.3 “DMA”).

AGP BUS OVERVIEW
NOTE: For a detailed description of AGP bus operations refer to the AGP Interface
Specification Rev. 2.0 available at the following AGP forum web site:
The Accelerated Graphics Port (AGP) bus is specifically designed as an economical yet high-
performance interface for graphics adapters, especially those designed for 3D operations. The
AGP interface is designed to give graphics adapters dedicated pipelined access to system memory
for the purpose of off-loading texturing, z-buffering, and alpha blending used in 3D graphics
operations. By off-loading a large portion of 3D data to system memory the AGP graphics adapter
only requires enough memory for frame buffer (display image) refreshing.
4.3.1 BUS TRANSACTIONS
The operation of the AGP bus is based on the 66-MHz PCI specification but includes additional
mechanisms to increase bandwidth. During the configuration phase the AGP bus acts in
accordance with PCI protocol. Once graphics data handling operation is initiated, AGP-defined
protocols take effect. The AGP graphics adapter acts generally as the AGP master, but can also
behave as a “PCI” target during fast writes from the PCI bus controller.
Key differences between the AGP interface and the PCI interface are as follows:
♦
♦
Address phase and associated data transfer phase are disconnected transactions. Addressing
and data transferring occur as contiguous actions on the PCI bus. On the AGP bus a request
for data and the transfer of data may be separated by other operations.
Commands on the AGP bus specify system memory accesses only. Unlike the PCI bus,
commands involving I/O and configuration are not required or allowed. The system memory
address space used in AGP operations is the same linear space used by PCI memory space
commands, but is further specified by the graphics address re-mapping table (GART) of the
north bridge component.
♦
♦
Data transactions on the AGP bus involve eight bytes or multiples of eight bytes. The AGP
memory addressing protocol uses 8-byte boundaries as opposed to PCI’s 4-byte boundaries.
If a transfer of less than eight bytes is needed, the remaining bytes are filled with arbitrary
data that is discarded by the target.
Pipelined requests are defined by length or size on the AGP bus. The PCI bus defines transfer
lengths with the FRAME- signal.
There are two basic types of transactions on the AGP bus: data requests (addressing) and data
transfers. These actions are separate from each other.

Chapter 4 System Support
4.3.1.1 Data Request
Requesting data is accomplished in one of two ways; either multiplexed addressing (using the AD
lines for addressing/data) or demultiplexed (“sideband”) addressing (using the SBA lines for
addressing only and the AD lines for data only). Even though there are only eight SBA lines (as
opposed to the 32 AD lines) sideband addressing maximizes efficiency and throughput by
allowing the AD lines to be exclusively used for data transfers. Sideband addressing occurs at the
same rate (1X, 2X, 4X, or 8X) as data transfers. The differences in rates will be discussed in the
next section describing data transfers. Note also that sideband addressing is limited to 48 bits
(address bits 48-63 are assumed zero). The IGP component supports both SBA and AD
addressing, but the method and rate is selected by the AGP graphics adapter.
4.3.1.2 Data Transfers
Data transfers use the AD lines and occur as the result of data requests described previously. Each
transaction resulting from a request involves at least eight bytes, requiring the 32 AD lines to
handle at least two transfers per request. The AGP v.2.0 specification (used on D315 models)
supports three transfer rates: 1X, 2X, and 4X. The AGP v3.0 specification (used on d325 models)
supports a fourth transfer rate, 8X. Regardless of the rate used, the speed of the bus clock is
constant at 66 MHz. The following subsections describe how the use of additional strobe signals
makes possible higher transfer rates.
AGP 1X Transfers
During a AGP 1X transfer the 66-MHz CLK signal is used to qualify the control and data signals.
Each 4-byte data transfer is synchronous with one CLK cycle so it takes two CLK cycles for a
minimum 8-byte transfer (Figure 4-5 shows two 8-byte transfers). The GNT- and TRDY- signals
retain their traditional PCI functions. The ST0..3 signals are used for priority encoding, with
“000” for low priority and “001” indicating high priority. The signal level for AGP 1X transfers
may be 3.3 or 1.5 VDC.

AGP 2X Transfers
During AGP 2X transfers, clocking is basically the same as in 1X transfers except that the 66-
MHz CLK signal is used to qualify only the control signals. The data bytes are latched by an
additional strobe (AD_STBx) signal so that an 8-byte transfer occurs in one CLK cycle (Figure 4-
6). The first four bytes (DnA) are latched by the receiving agent on the falling edge of AD_STBx
and the second four bytes (DnB) are latched on the rising edge of AD_STBx. The signal level for
AGP 2X transfers may be 3.3 or 1.5 VDC.

The AGP 4X transfer rate allows sixteen bytes of data to be transferred in one clock cycle. As in

block DnA is latched by the falling edge of AD_STBx while DnB is latched by the falling edge of

SYSTEM RESOURCES
This section describes the availability and basic control of major subsystems, otherwise known as
resource allocation or simply “system resources.” System resources are provided on a priority
basis through hardware interrupts and DMA requests and grants.
4.4.1 INTERRUPTS
The microprocessor uses two types of hardware interrupts; maskable and nonmaskable. A
maskable interrupt can be enabled or disabled within the microprocessor by the use of the STI and
CLI instructions. A nonmaskable interrupt cannot be masked off within the microprocessor,
although it may be inhibited by hardware or software means external to the microprocessor.
4.4.1.1 Maskable Interrupts
The maskable interrupt is a hardware-generated signal used by peripheral functions within the
system to get the attention of the microprocessor. Peripheral functions produce a unique INTA-H
(PCI) or IRQ0-15 (ISA) signal that is routed to interrupt processing logic that asserts the interrupt
(INTR-) input to the microprocessor. The microprocessor halts execution to determine the source
of the interrupt and then services the peripheral as appropriate.
Figure 4-9 shows the routing of PCI and ISA interrupts. Most IRQs are routed through the I/O
controller, which contains a serializing function. A serialized interrupt stream is applied to the
MCP component.

8259 Mode
The 8259 mode handles interrupts IRQ0-IRQ15 in the legacy (AT-system) method using 8259-
equivalent logic. Table 4-5 lists the standard source configuration for maskable interrupts and
their priorities in 8259 mode. If more than one interrupt is pending, the highest priority (lowest
number) is processed first.

Chapter 4 System Support
The PCI interrupts can be configured by PCI Configuration Registers 60h..63h to share the
standard ISA interrupts (IRQn).
NOTE: The APIC mode is supported by the Windows NT, Windows 2000, and
Windows XP operating systems. Systems running the Windows 95 or 98 operating
system will need to run in 8259 mode.
Maskable interrupt processing is controlled and monitored through standard AT-type I/O-mapped
registers. These registers are listed in Table 4-6.

The initialization and operation of the interrupt control registers follows standard AT-type
protocol.
4.4.1.2 Non-Maskable Interrupts
Non-maskable interrupts cannot be masked (inhibited) within the microprocessor itself but may be
maskable by software using logic external to the microprocessor. There are two non-maskable
interrupt signals: the NMI- and the SMI-. These signals have service priority over all maskable
interrupts, with the SMI- having top priority over all interrupts including the NMI-.
NMI- Generation
The Non-maskable Interrupt (NMI-) signal can be generated by one of the following actions:
♦
♦
Parity errors detected on a PCI bus (activating SERR- or PERR-).
Microprocessor internal error (activating IERRA or IERRB)
The SERR- and PERR- signals are routed through the MCP or MCP-2 component, which in turn
activates the NMI to the microprocessor.

Functions not related to NMI activity.
After the active NMI has been processed, status bits <7> or <6> are cleared by pulsing bits <2> or
<3> respectively.
The NMI Enable Register (070h, <7>) is used to enable/disable the NMI signal. Writing 80h to
this register masks generation of the NMI-. Note that the lower six bits of register at I/O port 70h
affect RTC operation and should be considered when changing NMI- generation status.
SMI- Generation
The SMI- (System Management Interrupt) is typically used for power management functions.
When power management is enabled, inactivity timers are monitored. When a timer times out,
SMI- is asserted and invokes the microprocessor’s SMI handler. The SMI handler works with the
APM BIOS to service the SMI- according to the cause of the timeout.
Although the SMI- is primarily used for power management the interrupt is also employed for the
QuickLock/QuickBlank functions as well.

4.4.2 DIRECT MEMORY ACCESS
Direct Memory Access (DMA) is a method by which a device accesses system memory without
involving the microprocessor. Although the DMA method has been traditionally used to transfer
blocks of data to or from an ISA I/O device, PCI devices may also use DMA operation as well.
The DMA method reduces the amount of CPU interactions with memory, freeing the CPU for
other processing tasks.
NOTE: This section describes DMA in general. For detailed information regarding
DMA operation, refer to the data manual for the Intel MCP component.
The MCP component includes the equivalent of two 8237 DMA controllers cascaded together to
provide eight DMA channels, each (excepting channel 4) configurable to a specific device. Table
4-7 lists the default configuration of the DMA channels.

All channels in DMA controller 1 operate at a higher priority than those in controller 2. Note that
channel 4 is not available for use other than its cascading function for controller 1. The DMA
controller 2 can transfer words only on an even address boundary. The DMA controller and page
register define a 24-bit address that allows data transfers within the address space of the CPU.
In addition to device configuration, each channel can be configured (through PCI Configuration
Registers) for one of two modes of operation:
♦
♦
LPC DMA
PC/PCI DMA
The LPC DMA mode uses the LPC bus to communicate DMA channel control and is
implemented for devices using DMA through the LPC47B367 I/O controller such as the diskette
drive controller.
The PC/PCI DMA mode uses the REQ#/GNT# signals to communicate DMA channel control and
is used by PCI expansion devices.

DMA controller 1 can move up to 64 Kbytes of data per DMA transfer. DMA controller 2 can
move up to 64 Kwords (128 Kbytes) of data per DMA transfer. Word DMA operations are only
possible between 16-bit memory and 16-bit peripherals.
The RAM refresh is designed to perform a memory read cycle on each of the 512 row addresses
in the DRAM memory space. Refresh operations are used to refresh memory on the 32-bit
memory bus and the ISA bus. The refresh address is provided on lines SA00 through SA08.
Address lines LA23..17, SA18,19 are driven low.
The remaining address lines are in an undefined state during the refresh cycle. The refresh
operations are driven by a 69.799-KHz clock generated by Interval Timer 1, Counter 1. The
refresh rate is 128 refresh cycles in 2.038 ms.

REAL-TIME CLOCK AND CONFIGURATION MEMORY
The Real-time clock (RTC) and configuration memory (also referred to as “CMOS”) functions are
provided by the MCP component and is MC146818-compatible. As shown in the following
figure, the MCP component provides 256 bytes of battery-backed RAM divided into two 128-byte
configuration memory areas. The RTC uses the first 14 bytes (00-0Dh) of the standard memory
area. All locations of the standard memory area (00-7Fh) can be directly accessed using
conventional OUT and IN assembly language instructions through I/O ports 70h/71h, although the
suggested method is to use the INT15 AX=E823h BIOS call.

A lithium 3-VDC battery is used for maintaining the RTC and configuration memory while the
system is powered down. The battery is located in a battery holder on the system board and has a
life expectancy of about three years. When the battery has expired it is replaced with a Renata
CR2032 or equivalent 3-VDC lithium battery.
4.6.1 CLEARING CMOS
The contents of configuration memory (including the Power-On Password) can be cleared by the
following procedure:
1. Turn off the unit and disconnect the AC power cord from the outlet and/or system unit.
2. Remove the chassis hood (cover) and insure that no LEDs on the system board are
illuminated.
3. On the JBAT1 header, move the jumper from pins 1 and 2 to pins 2 and 3. Leave the jumper
on pins 2 and 3 for about 5 seconds. This action will ground the battery input to the CMOS
circuitry.
4. Replace the jumper onto pins 1 and 2.
5. Replace the chassis hood (cover).
6. Reconnect the AC power cord to the outlet and/or system unit and reboot the system.
To clear only the Power-On Password refer to section 4.7.1.1.

4.6.2 CMOS ARCHIVE AND RESTORE
During the boot process the BIOS saves a copy of CMOS to the flash ROM. If the system
becomes unusable, the last good copy of CMOS can be recalled using the power-override function
as follows:
1. With the unit powered down, press and release the power button to initiate the boot sequence.
2. Immediately after releasing the power button, press it again and hold (typically at least four
seconds) until the unit powers off again. This action will be recorded as a power button
override event.
3. Press and release the power button once more, initiating the boot sequence that should detect
the occurrence of an override event and load the backup copy of CMOS, allowing the system
to boot.
4.6.3 STANDARD CMOS LOCATIONS
Table 4-11 and the following paragraphs describe standard configuration memory locations 0Ah-
3Fh. These locations are accessible through using OUT/IN assembly language instructions using

SYSTEM MANAGEMENT
This section describes functions having to do with security, power management, temperature, and
overall status. These functions are handled by hardware and firmware (BIOS) and generally
configured through the Setup utility.
4.7.1 SECURITY FUNCTIONS
This system includes various features that provide different levels of security. Note that this
subsection describes only the hardware functionality (including that supported by Setup) and
does not describe security features that may be provided by the operating system and application
software.
4.7.1.1 Power-On Password
This system includes a power-on password, which may be enabled or disabled (cleared) through a
jumper on the system board. The password is stored in configuration memory (CMOS) and if
enabled and then forgotten will require that either the password be cleared (preferable solution
and described below) or the entire CMOS be cleared (refer to section 4.6).
To clear only the password, use the following procedure:
1. Turn off the system and disconnect the AC power cord from the outlet and/or system unit.
2. Remove the cover (hood) as described in the appropriate User Guide or Service Reference
Guide. Insure that any system board LEDs are off (not illuminated).
3. Locate the password clear header labeled JCMOS1 and move the jumper from pins 1 and 2 to
pins 2 and 3.
4. Replace the cover.
5. Re-connect the AC power cord to the AC outlet and/or system unit.
6. Turn on the system. The POST routine will clear and disable the password.
7. To re-enable the password feature, repeat steps 1-6, replacing the jumper on pins 1 and 2 of
header JCMOS1.
4.7.1.2 Setup Password
The Setup utility may be configured to be always changeable or changeable only by entering a
password. The password is held on CMOS and, if forgotten, will require that CMOS be cleared
(refer to section 4.6).

These systems include a chassis cutout (on the rear panel) for the attachment of a cable lock
mechanism.
4.7.1.4 I/O Interface Security
The serial, parallel, USB, and diskette interfaces may be disabled individually through the Setup
utility to guard against unauthorized access to a system. In addition, the ability to write to or boot
from a removable media drive (such as the diskette drive) may be enabled through the Setup
utility. The disabling of the serial, parallel, and diskette interfaces are a function of the
LPC47B367 I/O controller. The USB ports are controlled through the MCP.

4.7.4 THERMAL SENSING AND COOLING
These systems feature variable-speed fans that are controlled through temperature sensing logic
on the system board and/or in the power supply. Typical cooling conditions include the
following:
1. Normal – Low fan speed.
2. Hot processor – ASIC directs Speed Control logic to increase speed of fan(s).
3. Hot power supply – Power supply increases speed of fan(s).
4. Sleep state – Fan(s) turned off. Hot processor or power supply will result in starting fan(s).
High and low thermal parameters are programmed into the ASIC by BIOS during POST. If the
high thermal parameter is reached then the fan(s) will be turned on full speed and the Therm-
signal will be asserted.
The system board provides connections for a heatsink-mounted CPU fan and a chassis fan, both
which complement the power supply fan. The system supports the use of variable-speed fans that
are regulated according to the temperature measured by an AMD1030 temperature controller.

Chapter 4 System Support
4.7.4.1 Cooling for D315 Models
The temperature controller produces the Fan CMD (which varies from 0 to +2.5 VDC) that is
applied to the speed control circuitry of the power supply assembly. The output of the speed
control circuitry controls the power supply assembly’s internal fan and is also routed back to the
system board and, in the default jumper configuration, is applied as the Fan Sink signal to the
negative terminal of the connected fans. The default jumper configuration also applies + 5 VDC to
the positive terminal of the fans. With the Fan CMD signal being varied from +0.5 to -7 VDC, the
chassis and CPU fans will be driven by a voltage from about +5 to +12 VDC, depending on the
processor temperature.
In a characteristically warm environment or should the speed regulation circuitry be inadequate or
fail it may be desirable to have the fans driven by a constant +12 VDC by configuring both
FAN_SEL jumpers to pins 1 and 2.
Note that the power supply assembly fan operates independently of the CPU and chassis fans.
CAUTION: Both FAN_SELn jumpers must have the same configuration (jumpers on
the same pins). Different jumper settings (one jumper on pins 1 and 2 and the other
jumper on pins 2 and 3) may result in equipment damage.

Technical Reference Guide
4.7.4.2 Cooling for d325 Models
The fan control logic on the d325 model differs from the D315 system in that fans are controlled
by the system board logic. The fans are driven by a constant positive 12 volts on one side and a
negative voltage that is variable through the Fan Cntrl logic. A Hardware Monitor ASIC monitors
the temperature of the processor and changes the duty cycle of the Fan PWM to increase or
decrease fan speed based on the processor temperature. The Fan Clamp signal is initiated by the
BIOS and produced by the GPIO at boot time to ensure that the fans start at boot time.
NOTE: A protection mechanism is provided where the processor threshold
temperature programmed into the Hardware Monitor ASIC is temporarily set by the
BIOS to a lower than normal level during the initial start up to protect against the
possibility of an incorrectly installed heat sink. If during the boot period the processor’s
temperature reaches 100° C the hardware Monitor will assert the Therm signal causing
the I/O Controller to de-assert the PS On signal, which will shut down the power supply.
If the processor does not reach 100° C during the boot sequence the BIOS then re-sets
the thermal threshold to the run-time level of 125° C

The LPC47B367 I/O controller contains various functions such as the keyboard/mouse interfaces,
diskette interface, serial interfaces, and parallel interface. While the control of these interfaces
uses standard AT-type I/O addressing (as described in chapter 5) the configuration of these
functions uses indexed ports unique to the LPC47B367. In these systems, hardware strapping
selects I/O addresses 02Eh and 02Fh at reset as the Index/Data ports for accessing the logical
devices within the LPC47B367. Table 4-15 lists the PnP standard control registers for the
LPC47B367.

For a detailed description of registers refer to appropriate SMC documentation.
The configuration registers are accessed through I/O registers 2Eh (index) and 2Fh (data) after the
configuration phase has been activated by writing 55h to I/O port 2Eh. The desired interface
(logical device) is initiated by firmware selecting logical device number of theLPC47B347 using
the following sequence:
1. Write 07h to I/O register 2Eh.
2. Write value of logical device to I/O register 2Fh.
3. Write 30h to I/O register 2Eh.
4. Write 01h to I/O register 2Fh (this activates the interface).
Writing AAh to 2Eh deactivates the configuration phase.

I/O security – The parallel, serial, and diskette interfaces may be disabled individually by
software and the LPC47B367’s disabling register locked. If the disabling register is locked, a
system reset through a cold boot is required to gain access to the disabling (Device Disable)
register.
Legacy/ACPI power button mode control – The LPC47B367 receives the pulse signal from
the system’s power button and produces the PS On signal according to the mode (legacy or
ACPI) selected. Refer to chapter 7 for more information regarding power management.

ENHANCED IDE INTERFACE
The enhanced IDE (EIDE) interface consists of primary and secondary controllers integrated into
the south bridge component of the chipset. Two 40-pin IDE connectors (one for each controller)
are included on the system board. Each controller can be configured independently for the
following modes of operation:
♦
♦
♦
Programmed I/O (PIO) mode – CPU controls drive transactions through standard I/O mapped
registers of the IDE drive.
8237 DMA mode – CPU offloads drive transactions using DMA protocol with transfer rates
up to 16 MB/s.
Ultra ATA/100 mode – Preferred bus mastering source-synchronous protocol providing
transfer rates of 100 MB/s.
5.2.1 IDE PROGRAMMING
The IDE interface is configured as a PCI device during POST and controlled through I/O-mapped
registers at runtime. Operating systems other than DOS or Windows may require using Setup
(F10) for drive configuration.

5.2.2 IDE CONNECTOR
This system uses a standard 40-pin connector for the primary IDE device and connects (via a
cable) to the hard drive. Note that some signals are re-defined for UATA/33 and higher modes,
which require a special 80-conductor cable (supplied) designed to reduce cross-talk. Device
power is supplied through a separate connector.

DISKETTE DRIVE INTERFACE
The diskette drive interface supports up to two diskette drives, each of which use a common cable
connected to a standard 34-pin diskette drive connector. Models that come standard with a 3.5-
inch 1.44-MB diskette drive will have the diskette drive installed as drive A. The drive
designation is determined by which connector is used on the diskette drive cable. The drive
attached to the end connector is drive A while the drive attached to the second (next to the end)
connector is drive B.
On all models, the diskette drive interface function is integrated into the LPC47B367 super I/O
component. The internal logic of the I/O controller is software-compatible with standard 82077-
type logic. The diskette drive controller has three operational phases in the following order:
♦
♦
♦
Command phase - The controller receives the command from the system.
Execution phase - The controller carries out the command.
Results phase - Status and results data is read back from the controller to the system.
The Command phase consists of several bytes written in series from the CPU to the data register
(3F5h/375h). The first byte identifies the command and the remaining bytes define the parameters
of the command. The Main Status register (3F4h/374h) provides data flow control for the diskette
drive controller and must be polled between each byte transfer during the Command phase.
The Execution phase starts as soon as the last byte of the Command phase is received. An
Execution phase may involve the transfer of data to and from the diskette drive, a mechnical
control function of the drive, or an operation that remains internal to the diskette drive controller.
Data transfers (writes or reads) with the diskette drive controller are by DMA, using the DRQ2
and DACK2- signals for control.
The Results phase consists of the CPU reading a series of status bytes (from the data register
(3F5h/375h)) that indicate the results of the command. Note that some commands do not have a
Result phase, in which case the Execution phase can be followed by a Command phase.
During periods of inactivity, the diskette drive controller is in a non-operation mode known as the
Idle phase.

Technical Reference Guide
5.3.1 DISKETTE DRIVE PROGRAMMING
Programming the diskette drive interface consists of configuration, which occurs typically during
POST, and control, which occurs at runtime.
5.3.1.1 Diskette Drive Interface Configuration
The diskette drive controller must be configured for a specific address and also must be enabled
before it can be used. Address selection and enabling of the diskette drive interface are affected by
firmware through the PnP configuration registers of the LPC47B367 I/O controller during POST.
The configuration registers are accessed through I/O registers 2Eh (index) and 2Fh (data) after the
configuration phase has been activated by writing 55h to I/O port 2Eh. The diskette drive I/F is
initiated by firmware selecting logical device 0 of the LPC47B367 using the following sequence:
1. Write 07h to I/O register 2Eh.
2. Write 00h to I/O register 2Fh (this selects the diskette drive I/F).
3. Write 30h to I/O register 2Eh.
4. Write 01h to I/O register 2Fh (this activates the interface).
Writing AAh to 2Eh deactivates the configuration phase. The diskette drive I/F configuration
registers are listed in the following table:

5.3.1.2 Diskette Drive Interface Control
The BIOS function INT 13 provides basic control of the diskette drive interface. The diskette
drive interface can be controlled by software through the LPC47B367’s I/O-mapped registers
listed in Table 5-5. The diskette drive controller of the LPC47B367 operates in the PC/AT mode
in these systems.

SERIAL INTERFACE
All models include at least one RS-232-C type serial interface to transmit and receive
asynchronous serial data with external devices. The serial interface function is provided by the
LPC47B367 I/O controller component that includes two NS16C550-compatible UARTs.
The UART supports the standard baud rates up through 115200, and also special high speed rates
of 239400 and 460800 baud. The baud rate of the UART is typically set to match the capability of
the connected device. While most baud rates may be set at runtime, baud rates 230400 and
460800 must be set during the configuration phase.
5.4.1 SERIAL CONNECTOR
The serial interface uses a DB-9 connector as shown in the following figure with the pinout listed
in Table 5-5.

PARALLEL INTERFACE
All models include a parallel interface for connection to a peripheral device that has a compatible
interface, the most common being a printer. The parallel interface function is integrated into the
LPC47B367 I/O controller component and provides bi-directional 8-bit parallel data transfers with
a peripheral device. The parallel interface supports three main modes of operation:
♦
♦
♦
Standard Parallel Port (SPP) mode
Enhanced Parallel Port (EPP) mode
Extended Capabilities Port (ECP) mode
These three modes (and their submodes) provide complete support as specified for an IEEE 1284
parallel port.
5.5.1 STANDARD PARALLEL PORT MODE
The Standard Parallel Port (SPP) mode uses software-based protocol and includes two sub-modes
of operation, compatible and extended, both of which can provide data transfers up to 150 KB/s.
In the compatible mode, CPU write data is simply presented on the eight data lines. A CPU read
of the parallel port yields the last data byte that was written.
The following steps define the standard procedure for communicating with a printing device:
1. The system checks the Printer Status register. If the Busy, Paper Out, or Printer Fault signals
are indicated as being active, the system either waits for a status change or generates an error
message.
2. The system sends a byte of data to the Printer Data register, then pulses the printer STROBE
signal (through the Printer Control register) for at least 500 ns.
3. The system then monitors the Printer Status register for acknowledgment of the data byte
before sending the next byte.
In extended mode, a direction control bit (CTR 37Ah, bit <5>) controls the latching of output data
while allowing a CPU read to fetch data present on the data lines, thereby providing bi-directional
parallel transfers to occur.
The SPP mode uses three registers for operation: the Data register (DTR), the Status register
(STR) and the Control register (CTR). Address decoding in SPP mode includes address lines A0
and A1.

Chapter 5 Input/Output Interfaces
5.5.2 ENHANCED PARALLEL PORT MODE
In Enhanced Parallel Port (EPP) mode, increased data transfers are possible (up to 2 MB/s) due to
a hardware protocol that provides automatic address and strobe generation. EPP revisions 1.7 and
1.9 are both supported. For the parallel interface to be initialized for EPP mode, a negotiation
phase is entered to detect whether or not the connected peripheral is compatible with EPP mode. If
compatible, then EPP mode can be used. In EPP mode, system timing is closely coupled to EPP
timing. A watchdog timer is used to prevent system lockup.
Five additional registers are available in EPP mode to handle 16- and 32-bit CPU accesses with
the parallel interface. Address decoding includes address lines A0, A1, and A2.
5.5.3 EXTENDED CAPABILITIES PORT MODE
The Extended Capabilities Port (ECP) mode, like EPP, also uses a hardware protocol-based
design that supports transfers up to 2 MB/s. Automatic generation of addresses and strobes as well
as Run Length Encoding (RLE) decompression is supported by ECP mode. The ECP mode
includes a bi-directional FIFO buffer that can be accessed by the CPU using DMA or programmed
I/O. For the parallel interface to be initialized for ECP mode, a negotiation phase is entered to
detect whether or not the connected peripheral is compatible with ECP mode. If compatible, then
ECP mode can be used.
Ten control registers are available in ECP mode to handle transfer operations. In accessing the
control registers, the base address is determined by address lines A2-A9, with lines A0, A1, and
A10 defining the offset address of the control register. Registers used for FIFO operations are
accessed at their base address + 400h (i.e., if configured for LPT1, then 378h + 400h = 778h).
The ECP mode includes several sub-modes as determined by the Extended Control register. Two
submodes of ECP allow the parallel port to be controlled by software. In these modes, the FIFO
is cleared and not used, and DMA and RLE are inhibited.

5.5.4 PARALLEL INTERFACE PROGRAMMING
Programming the parallel interface consists of configuration, which typically occurs during POST,
and control, which occurs during runtime.
5.5.4.1 Parallel Interface Configuration
The parallel interface must be configured for a specific address range (LPT1, LPT2, etc.) and also
must be enabled before it can be used. When configured for EPP or ECP mode, additional
considerations must be taken into account. Address selection, enabling, and EPP/ECP mode
parameters of the parallel interface are affected through the PnP configuration registers of the
LPC47B367 I/O controller. Address selection and enabling are automatically done by the BIOS
during POST but can also be accomplished with the Setup utility and other software.
The parallel interface configuration registers are listed in the following table:

5.5.4.2 Parallel Interface Control
The BIOS function INT 17 provides simplified control of the parallel interface. Basic functions
such as initialization, character printing, and printer status are provide by subfunctions of INT 17.
The parallel interface is controllable by software through a set of I/O mapped registers. The
number and type of registers available depends on the mode used (SPP, EPP, or ECP). Table 5-11

KEYBOARD/POINTING DEVICE INTERFACE
The keyboard/pointing device interface function is provided by the LPC47B367 I/O controller
component, which integrates 8042-compatible keyboard controller logic (hereafter referred to as
simply the “8042”) to communicate with the keyboard and pointing device using bi-directional
serial data transfers. The 8042 handles scan code translation and password lock protection for the
keyboard as well as communications with the pointing device. This section describes the interface
itself. The keyboard is discussed in the Appendix C.
5.6.1 KEYBOARD INTERFACE OPERATION
The data/clock link between the 8042 and the keyboard is uni-directional for Keyboard Mode 1
and bi-directional for Keyboard Modes 2 and 3. (These modes are discussed in detail in Appendix
C). This section describes Mode 2 (the default) mode of operation.
Communication between the keyboard and the 8042 consists of commands (originated by either
the keyboard or the 8042) and scan codes from the keyboard. A command can request an action or
indicate status. The keyboard interface uses IRQ1 to get the attention of the CPU.
The 8042 can send a command to the keyboard at any time. When the 8042 wants to send a
command, the 8042 clamps the clock signal from the keyboard for a minimum of 60 us. If the
keyboard is transmitting data at that time, the transmission is allowed to finish. When the 8042 is
ready to transmit to the keyboard, the 8042 pulls the data line low, causing the keyboard to
respond by pulling the clock line low as well, allowing the start bit to be clocked out of the 8042.
The data is then transferred serially, LSb first, to the keyboard (Figure 5-5). An odd parity bit is
sent following the eighth data bit. After the parity bit is received, the keyboard pulls the data line
low and clocks this condition to the 8042. When the keyboard receives the stop bit, the clock line
is pulled low to inhibit the keyboard and allow it to process the data.

Technical Reference Guide
Control of the data and clock signals is shared by the 8042 and the keyboard depending on the
originator of the transferred data. Note that the clock signal is always generated by the keyboard.
After the keyboard receives a command from the 8042, the keyboard returns an ACK code. If a
parity error or timeout occurs, a Resend command is sent to the 8042.
Table 5-13 lists and describes commands that can be issued by the 8042 to the keyboard.

5.6.2 POINTING DEVICE INTERFACE OPERATION
The pointing device (typically a mouse) connects to a 6-pin DIN-type connector that is identical to
the keyboard connector both physically and electrically. The operation of the interface (clock and
data signal control) is the same as for the keyboard. The pointing device interface uses the IRQ12
interrupt.
5.6.3 KEYBOARD/POINTING DEVICE INTERFACE PROGRAMMING
Programming the keyboard interface consists of configuration, which occurs during POST, and
control, which occurs during runtime.
5.6.3.1 8042 Configuration
The keyboard/pointing device interface must be enabled and configured for a particular speed
before it can be used. Enabling and speed parameters of the 8042 logic are affected through the
PnP configuration registers of the LPC47B367 I/O controller. Enabling and speed control are
automatically set by the BIOS during POST but can also be accomplished with the Setup utility
and other software.

5.6.3.2 8042 Control
The BIOS function INT 16 is typically used for controlling interaction with the keyboard. Sub-
functions of INT 16 conduct the basic routines of handling keyboard data (i.e., translating the
keyboard’s scan codes into ASCII codes). The keyboard/pointing device interface is accessed by
the CPU through I/O mapped ports 60h and 64h, which provide the following functions:
♦
♦
♦
♦
Output buffer reads
Input buffer writes
Status reads
Command writes
Ports 60h and 64h can be accessed using the IN instruction for a read and the OUT instruction for
a write. Prior to reading data from port 60h, the “Output Buffer Full” status bit (64h, bit <0>)
should be checked to ensure data is available. Likewise, before writing a command or data, the
“Input Buffer Empty” status bit (64h, bit <1>) should also be checked to ensure space is available.
I/O Port 60h
I/O port 60h is used for accessing the input and output buffers. This register is used to send and
receive data from the keyboard and the pointing device. This register is also used to send the
second byte of multi-byte commands to the 8042 and to receive responses from the 8042 for
commands that require a response.
A read of 60h by the CPU yields the byte held in the output buffer. The output buffer holds data
that has been received from the keyboard and is to be transferred to the system.
A CPU write to 60h places a data byte in the input byte buffer and sets the CMD/ DATA bit of the
Status register to DATA. The input buffer is used for transferring data from the system to the
keyboard. All data written to this port by the CPU will be transferred to the keyboard except bytes
that follow a multibyte command that was written to 64h
I/O Port 64h
I/O port 64h is used for reading the status register and for writing commands. A read of 64h by
the CPU will yield the status byte defined as follows:
Bit
7..4
3
Function
General Purpose Flags.
CMD/DATA Flag (reflects the state of A2 during a CPU write).
0 = Data
1 = Command
2
1
General Purpose Flag.
Input Buffer Full. Set (to 1) upon a CPU write. Cleared by
IN A, DBB instruction.
0
Output Buffer Full (if set). Cleared by a CPU read of the
buffer.
A CPU write to I/O port 64h places a command value into the input buffer and sets the
CMD/DATA bit of the status register (bit <3>) to CMD.

5.7.1 USB DATA FORMATS
The USB I/F uses non-return-to-zero inverted (NRZI) encoding for data transmissions, in which a
1 is represented by no change (between bit times) in signal level and a 0 is represented by a
change in signal level. Bit stuffing is employed prior to NRZ1 encoding so that in the event a
string of 1’s is transmitted (normally resulting in a steady signal level) a 0 is inserted after every
six consecutive 1’s to ensure adequate signal transitions in the data stream. The USB
transmissions consist of packets using one of four types of formats (Figure 5-8) that include two
or more of seven field types.
♦
♦
Sync Field – 8-bit field that starts every packet and is used by the receiver to align the
incoming signal with the local clock.
Packet Identifier (PID) Field – 8-bit field sent with every packet to identify the attributes (in.
out, start-of-frame (SOF), setup, data, acknowledge, stall, preamble) and the degree of error
correction to be applied.
♦
♦
♦
Address Field – 7-bit field that provides source information required in token packets.
Endpoint Field – 4-bit field that provides destination information required in token packets.
Frame Field – 11-bit field sent in Start-of-Frame (SOF) packets that are incremented by the
host and sent only at the start of each frame.
♦
♦
Data Field – 0-1023-byte field of data.
Cyclic Redundancy Check (CRC) Field – 5- or 16-bit field used to check transmission
integrity.

AUDIO SUBSYSTEM
This system includes an embedded Sound Blaster-compatible audio subsystem with front panel-
accessible headphone and microphone jacks.
5.8.1 FUNCTIONAL ANALYSIS
A block diagram of the audio subsystem is shown in Figure 5-10. These systems use the AC’97
Audio Controller of the MCP component to access and control an Analog Devices AD1885 or
AD1981B Audio Codec, which provides the analog-to-digital (ADC) and digital-to-analog (DAC)
conversions as well as the mixing functions. All control functions such as volume, audio source
selection, and sampling rate are controlled through software over the PCI bus through the AC97
Audio Controller of the MCP component. Control data and digital audio streams (record and
playback) are transferred between the Audio Controller and the Audio Codec over the AC97 Link
Bus.
This system incorporates Business Audio, which has the codec stereo analog output applied
through headphone jacks and switch logic to a mono 3-watt amplifier that drives a 16-ohm
speaker. The switch logic allows the system to provide headphone functionality with or without
the front panel assembly installed.
The analog interfaces allowing connection to external audio devices include:
Mic In - This input uses a three-conductor (stereo) mini-jack that is specifically designed for
connection of a condenser microphone with an impedance of 10-K ohms. This is the default
recording input after a system reset. Either the front or rear panel microphone jack is available for
use (but not simultaneously).
Line In - This input uses a three-conductor (stereo) mini-jack that is specifically designed for
connection of a high-impedance (10k-ohm) audio source such as a tape deck.
Headphones Out - This input uses a three-conductor (stereo) mini-jack that is designed for
connecting a set of 16-ohm (nom.) stereo headphones or powered speakers. Plugging into the
Headphones jack mutes the signal to the internal speaker.
Line Out - This output uses a three-conductor (stereo) mini-jack for connecting left and right
channel line-level signals (20-K ohm impedance). A typical connection would be to a tape
recorder’s Line In (Record In) jacks, an amplifier’s Line In jacks, or to powered speakers that
contain amplifiers. Plugging into the Line Out mutes the internal speaker.

5.8.3 AC97 LINK BUS
The audio controller and the audio codec communicate over a five-signal AC97 Link Bus (Figure
5-11). The AC97 Link Bus includes two serial data lines (SD OUT/SD IN) that transfer control
and PCM audio data serially to and from the audio codec using a time-division multiplexed
(TDM) protocol. The data lines are qualified by a 12.288 MHz BIT_CLK signal driven by the
audio codec. Data is transferred in frames synchronized by the 48-KHz SYNC signal, which is
derived from the clock signal and driven by the audio controller. The SYNC signal is high during
the frame’s tag phase then falls during T17 and remains low during the data phase. A frame
consists of one 16-bit tag slot followed by twelve 20-bit data slots. When asserted (typically
during a power cycle), the RESET- signal (not shown) will reset all audio registers to their default
values.

5.8.4 AUDIO CODEC
The audio codec provides pulse code modulation (PCM) coding and decoding of audio
information as well as the selection and/or mixing of analog channels. As shown in Figure 5-12,
analog audio from a microphone, tape, or CD can be selected and, if to be recorded (saved) onto a
disk drive, routed through an analog-to-digital converter (ADC). The resulting left and right PCM
record data are muxed into a time-division-multiplexed (TDM) data stream (SD IN signal) that is
routed to the audio controller. Playback (PB) audio takes the reverse path from the audio
controller to the audio codec as SD OUT data and is decoded and processed by the digital-to-
analog converter (DAC). The codec supports simultaneous record and playback of stereo (left
and right) audio. The Sample Rate Generator may be set for sampling frequencies up to 48 KHz.
Analog audio may then be routed through 3D stereo enhancement processor or bypassed to the
output selector (SEL). The integrated analog mixer provides the computer control-console
functionality handling multiple audio inputs.
The D315 and D325 models use the Analog Devices AD1885 and the AD1981B respectively.
These devices differ in that the AD1885 includes a 3D analog processor while the AD1981B
includes an equalizer as well as SPDIF support.

NETWORK INTERFACE CONTROLLER
The HP d325 system includes a 10/100 Mbps network interface controller (NIC) consisting of a
82562-equivalent controller integrated into the 82801 ICH component coupled with a physical
interface (PHY) component and an RJ-45 jack with integral status LEDs (Figure 5-13). The
support firmware is contained in the system (BIOS) ROM. The NIC can operate in half- or full-
duplex modes, and provides auto-negotiation of both mode and speed. Half-duplex operation
features an Intel-proprietary collision reduction mechanism while full-duplex operation follows
the IEEE 802.3x flow control specification. Transmit and receive FIFOs of 3 kilobytes each
reduce the chance of overrun while waiting for bus access.

The Network Interface Controller includes the following features:
♦
♦
♦
♦
♦
♦
Fast Ethernet controller with 32-bit architecture and 3-KB TX/RX buffers.
Dual-mode support with auto-switching between 10BASE-T and 100BASE-TX.
Power down and Wake up support in both APM and ACPI environments (PME- and WOL).
Alert-on-LAN (AOL v1.0) support.
Link and Activity LED indicator drivers
AOL support for upgrade card
The controller features high and low priority queues and provides priority-packet processing for
networks that can support that feature. The controller’s micro-machine processes transmit and
receive frames independently and concurrently. Receive runt (under-sized) frames are not passed
on as faulty data but discarded by the controller, which also directly handles such errors as
collision detection or data under-run.
The NIC uses 3.3 VDC auxiliary power, which allows the controller to support Wake-On-LAN
(WOL) and Alert-On-LAN (AOL) functions while the main system is powered down.

Technical Reference Guide
NOTE: For the WOL and AOL features to function as described in the following
paragraphs, the system unit must be plugged into a live AC outlet. Controlling unit
power through a switchable power strip will, with the strip turned off, disable WOL and
AOL functionality.
5.9.1 WAKE ON LAN SUPPORT
The NIC supports the Wired-for-Management (WfM) standard of Wake-On-LAN (WOL) that
allows the system to be booted up from a powered-down or low-power condition upon the
detection of special packets received over a network. The NIC receives 3.3 VDC auxiliary power
while the system unit is powered down in order to process special packets. The detection of a
Magic Packet by the NIC results in the PME- signal on the PCI bus to be asserted, initiating
system wake-up from an ACPI S1 or S3 state.
5.9.2 ALERT ON LAN SUPPORT
Alert-On-LAN (AOL) support allows the NIC to communicate the occurrence of certain events
over a network even while the system unit is powered off. In a system-off (powered down)
condition the network function of the 82801 ICH component receives auxiliary +3.3 VDC power
(derived from the +5 VDC auxiliary power from the power supply assembly). Certain events
(listed in Table 5-24) will result in the network function of the ICH to transmit an appropriate pre-
constructed message over the network to a system management console.
Reportable AOL events are listed in the following table:
Table 5-24.

Chapter 5 Input/Output Interfaces
5.9.3 POWER MANAGEMENT SUPPORT
The NIC features Wired-for-Management (WfM) support providing system wake up from
network events (WOL) as well as generating system status messages (AOL) and supports both
APM and ACPI power management environments. The controller receives 3.3 VDC (auxiliary)
power as long as the system is plugged into a live AC receptacle, allowing support of wake-up
events occuring over a network while the system is powered down or in a low-power state.
5.9.3.1 APM Environment
The Advanced Power Management (APM) functionality of system wake up is implemented
through the system’s APM-compliant BIOS and the controller’s Magic Packet-compliant
hardware. This environment bypasses operating system (OS) intervention allowing a plugged in
unit to be turned on remotely over the network (i.e., “remote wake up”). In APM mode the
controller will respond upon receiving a Magic Packet, which is a packet where the node’s
address is repeated 16 times. Upon Magic packet detection, the controller initiates the boot
sequence.
5.9.3.2 ACPI Environment
The Advanced Configuration and Power Interface (ACPI) functionality of system wake up is
implemented through an ACPI-compliant OS and is the default power management mode. The
following wakeup events may be individually enabled/disabled through the supplied software
driver:
♦
Magic Packet – Packet with node address repeated 16 times in data portion
NOTE: The following functions are supported in NDIS5 drivers but implemented
through remote management software applications (such as LanDesk).
♦
♦
♦
♦
Individual address match – Packet with matching user-defined byte mask
Multicast address match – Packet with matching user-defined sample frame
ARP (address resolution protocol) packet
Flexible packet filtering – Packets that match defined CRC signature
The PROSet Application software (pre-installed and accessed through the System Tray or
Windows Control Panel) allows configuration of operational parameters such as WOL and duplex
mode.

FUNCTIONAL DESCRIPTION
The NVidia NForce 220 chipset includes a graphics processing unit (GPU) integrated into the
integrated graphics processor (IGP) component (Figure 6-1). The graphics controller can directly
drive an external, analog multi-scan monitor at resolutions up to and including 1920 x 1440
pixels. The GPU includes a memory management feature that allocates portions of system
memory for use as the frame buffer and for storing textures and 3D effects.
These systems may be upgraded by installing a separate AGP graphics card in the AGP slot,
which disables the onboard IGC.

7.2.2 POWER CONTROL
The power supply assembly is controlled digitally by the PS On signal (Figure 7-1). When PS On
is asserted, the Power Supply Assembly is activated and all voltage outputs are produced. When
PS On is de-asserted, the Power Supply Assembly is off and all voltages (except +5 AUX) are not
generated. Note that the +5 AUX voltage is always produced as long as the system is
connected to a live AC source.
7.2.2.1 Power Button
The PS On signal is typically controlled through the Power Button which, when pressed and
released, applies a negative (grounding) pulse to the power control logic. The resultant action of
pressing the power button depends on the state and mode of the system at that time and is
described as follows:
System State
Pressed Power Button Results In:
Off
Negative pulse, of which the falling edge results in power control logic asserting PS
On signal to Power Supply Assembly, which then initializes. ACPI four-second
counter is not active.
On, ACPI Disabled
On, ACPI Enabled
Negative pulse, of which the falling edge causes power control logic to de-assert the
PS On signal. ACPI four-second counter is not active.
Pressed and Released Under Four Seconds:
Negative pulse, of which the falling edge causes power control logic to
generate SMI-, set a bit in the SMI source register, set a bit for button status,
and start four-second counter. Software should clear the button status bit
within four seconds and the Suspend state is entered. If the status bit is
not cleared by software in four seconds PS On is de-asserted and the
power supply assembly shuts down (this operation is meant as a guard if
the OS is hung).
Pressed and Held At least Four Seconds Before Release:
If the button is held in for at least four seconds and then released, PS On is
negated, de-activating the power supply.

Chapter 7 Power and Signal Distribution
7.2.2.2 Wake Up Events
The PS On signal can be activated with a power “wake-up” of the system due to the occurrence of
a magic packet, serial port ring, or PCI power management (PME) event. These events can be
individually enabled through the Setup utility to wake up the system from a sleep (low power)
state.
NOTE: Wake-up functionality requires that certain circuits receive auxiliary power
while the system is turned off. The system unit must be plugged into a live AC outlet
for wake up events to function. Using an AC power strip to control system unit power
will disable wake-up event functionality.
The wake up sequence for each event occurs as follows:
Wake-On-LAN
The network interface controller (NIC) can be configured for detection of a “Magic Packet” and
wake the system up from sleep mode through the assertion of the PME- signal on the PCI bus.
Refer to Chapter 5, section 5.9, “Network Interface Controller” for more information.
Power Management Event
A power management event that asserts the PME- signal on the PCI bus can be enabled to cause
the power control logic to generate the PS On. Note that the PCI card must be PCI ver. 2.2
compliant to support this function.

Chapter 8 System BIOS
8.2
ROM FLASHING/UPGRADING
The system BIOS firmware is contained in a flash ROM device that can be re-written with BIOS
code (using the ROMPaq utility or a remote flash program) allowing easy upgrading, including
changing the splash screen displayed during the POST routine.
Upgrading the BIOS is not normally required but may be necessary if changes are made to the
unit’s operating system, hard drive, or processor. All BIOS ROM upgrades are available directly
from Hewlett-Packard. Flashing is done either locally with the CPQFLASH or HPQFlash
Windows program, a ROMPaq diskette, or remotely using the network boot function (described in
the section 8.3.2).
This system includes 64 KB of write-protected boot block ROM that provides a way to recover
from a failed flashing of the system BIOS ROM. If the BIOS ROM fails the flash check, the boot
block code provides the minimum amount of support necessary to allow booting the system from
the diskette drive and re-flashing the system ROM with a ROMPaq diskette. Note that if an
administrator password has been set in the system the boot block will prompt for this password by
illuminating the caps lock keyboard LED and displaying a message if video support is available.
A PS/2 keyboard must be used during bootblock operation.
Since video may not be available during the initial boot sequence the boot block routine uses the
Num Lock, Caps Lock, and Scroll Lock LEDs of the PS/2 keyboard to communicate the status of
the ROM flash as follows:

BOOT FUNCTIONS
The BIOS supports various functions related to the boot process, including those that occur during
the Power On Self-Test (POST) routine.
8.3.1 BOOT DEVICE ORDER
The default boot device order is as follows:
1. IDE CD-ROM drive (EL Torito CD images)
2. Diskette drive (A)
3. MultiBay device (A: or CD-ROM) if applicable
4. USB device
5. Hard drive (C)
6. Network interface controller
The order can be changed in the ROM-based Setup utility (accessed by pressing F10 when so
prompted during POST). Entries are displayed only if the actual device is attached, with the
exception of the USB device, which is always displayed even if a USB storage device is not
present. The hot IPL option is available through F9 during the POST routine. The order defined
by the Setup (F10) can be overridden once by pressing the F9 key during the boot process.
8.3.2 NETWORK BOOT (F12) SUPPORT
The BIOS supports booting the system to a network server. The function is accessed by pressing
the F12 key when prompted at the lower right hand corner of the display during POST. Booting to
a network server allows for such functions as:
♦
♦
♦
Flashing a ROM on a system without a functional operating system (OS).
Installing an OS.
Installing an application.

Chapter 8 System BIOS
8.3.3 MEMORY DETECTION AND CONFIGURATION
This system uses the Serial Presence Detect (SPD) method of determining the installed DIMM
configuration. The BIOS communicates with an EEPROM on each DIMM through the SMBus to
obtain data on the following DIMM parameters:
♦
♦
♦
♦
♦
Presence
Size
Type
Timing/CAS latency
Memory speed
NOTE: Refer to Chapter 3, “Processor/Memory Subsystem” for the SPD format and
DIMM data specific to this system.
The BIOS performs memory detection and configuration with the following steps:
1. Program the buffer strength control registers based on SPD data and the DIMM slots that are
populated.
2. Determine the common CAS latency that can be supported by the DIMMs.
3. Determine the memory size for each DIMM and program the graphics controller accordingly.
4. Enable refresh
5. Determine if the memory configuration will allow for double-clocked 133-MHz memory
operation and program the memory clock and IGP (see note below)
NOTE: The BIOS must read a value of 07h (indicating DDR) from SPD byte 02h of
each DIMM in order to validate the memory.
8.3.4 BOOT ERROR CODES
The BIOS provides visual and audible indications of a failed system boot by using the keyboard
LEDs and the system speaker. The error conditions are listed in the following table.

Allows user to enable or disable Master Boot
Record (MBR) Security. When enabled, the BIOS
rejects all requests to write to the MBR on the
current bootable disk. Each time the computer is
powered on or rebooted, the BIOS compares the
MBR of the current bootable disk to the previously-
saved MBR. If changes are detected, you are given
the option of saving the MBR on the current
bootable disk, restoring the previously-saved MBR,
or disabling MBR Security. You must know the
setup password, if one is set.
Master Boot Record Security
Note: Disable MBR Security before intentionally
changing the formatting or partitioning of the
current bootable disk. Several disk utilities (such as
FDISK and FORMAT) attempt to update the MBR.
If MBR Security is enabled and disk accesses are
being serviced by the BIOS, write requests to the
MBR are rejected, causing the utilities to report
errors. If MBR Security is enabled and disk

[1] Industry standard function.
All 32-bit protected-mode functions are accessed by using the industry-standard BIOS32 Service
Directory. Using the service directory involves three steps:
1. Locating the service directory.
2. Using the service directory to obtain the entry point for the client management functions.
3. Calling the client management service to perform the desired function.
The BIOS32 Service Directory is a 16-byte block that begins on a 16-byte boundary between the
physical address range of 0E0000h-0FFFFFh. The format is as follows:

Chapter 8 System BIOS
To support Windows NT an additional table to the BIOS32 table has been defined to contain 32-
bit pointers for the DDC locations. The Windows NT extension table is as follows:
; Extension to BIOS SERVICE directory table (next paragraph)
db
db

; 32-bit pointer
; byte size
; ESCD sig
; 32-bit pointer
; bytes size
?
“$ERB”

?
The service identifier for client management functions is “$CLM.” Once the service identifier is
found and the checksum verified, a FAR call is invoked using the value specified at offset 04h to
retrieve the CM services entry point. The following entry conditions are used for calling the
Desktop Management service directory:
INPUT:

8.5.1 SYSTEM ID AND ROM TYPE
Applications can use the INT 15, AX=E800h BIOS function to identify the type of system. This
function will return the system ID in the BX register. These systems have the following IDs and
ROM family types:
System
System ID
07D0h

The ROM family and version numbers can be verified with the Setup utility or the Compaq
Insight Manager or Diagnostics applications.
8.5.2 EDID RETRIEVE
The BIOS function INT 15, AX=E813h is a tri-modal call that retrieves the VESA extended
display identification data (EDID). Two subfunctions are provided: AX=E813h BH=00h retrieves
the EDID information while AX=E813h BX=01h determines the level of DDC support.
Input:

Chapter 8 System BIOS
8.5.3 TEMPERATURE STATUS
The BIOS includes a function (INT15, AX=E816h) to retrieve the status of a system’s interior
temperature. This function allows an application to check whether the temperature situation is at a
Normal, Caution, or Critical condition.
8.5.4 DRIVE FAULT PREDICTION
The Compaq BIOS directly supports Drive Fault Prediction for IDE-type hard drives. This feature
is provided through two Client Management BIOS calls. Function INT 15, AX=E817h is used to
retrieve a 512-byte block of drive attribute data while the INT 15, AX=E81Bh is used to retrieve
the drive’s warranty threshold data. If data is returned indicating possible failure then the
following message is displayed:
“1720-SMART Hard Drive detects imminent failure”
8.6
POWER MANAGEMENT FUNCTIONS
The BIOS provides two types of power management support: independent PM support ACPI
support.
NOTE: The D315 models support both the independent PM (aka “APM”) and the ACPI
Modes. The d325 models support only the ACPI mode.
8.6.1 INDEPENDENT PM SUPPORT (D315 only)
The BIOS can provide power management (PM) of the system independently from an operating
system that doesn’t support APM (including DOS, Unix, NT & older versions of OS/2). In the
Independent PM environment the BIOS and hardware timers determine when to switch the system
to a different power state. State switching is not reported to the OS.
8.6.1.1 Staying Awake In Independent PM
There are two "Time-out to Standy" timers used in independent PM: the System Timer
and the IDE Hard Drive Timer.

Technical Reference Guide
System Timer
In POST, the BIOS enables a timer in the south bridge component that generates an SMI once per
minute. When the BIOS detects the SMI it checks status bits in the south bridge for device
activity. If any of the device activity status bits are set at the time of the 1-minute SMI, BIOS
resets the time-out minute countdown. The system timer can be configured through the Setup
utility for counting down 0, 5, 10, 15, 20, 30, 40, 50, 60, 120, 180, or 240 minutes. The following
devices are checked for activity:
♦
♦
♦
♦
♦
Keyboard
Mouse
Serial port(s)
Parallel port
IDE primary controller
NOTE: The secondary controller is NOT included. This is done to support
auto-sense of a CD-ROM insertion (auto-run) in case Windows or NT is
running. ote also that SCSI drive management is the responsibility of the SCSI
river. Any IDE hard drive access resets the hard drive timer.
IDE Hard Drive Timer
During POST, an inactivity timer each IDE hard drive is set to control hard drive spin down.
Although this activity is independent of the system timer, the system will not go to sleep until the
primary IDE controller has been inactive for the system time-out time. The hard drive timer can
be configured through the Setup utility for being disabled or counting down 10, 15, 20, 30, 60,
120, 180, or 240 minutes, after which time the hard drive will spin down.
8.6.1.2 Going to Sleep in Independent PM
When a time-out timer expires, Standby for that timer occurs.
System Standby
When the system acquires the Standby mode the BIOS blanks the screen. Since the hard
drive inactivity timer is in the drive and triggered by drive access, the system can be in
Standby with the hard drives still spinning (awake).
NOTE: The BIOS does not turn the fan(s) off (as on previous products).
IDE Hard Drive Standby
During hard drive standby the platters stop spinning. Depending on drive type, some hard drives
will also cut power to some of the drive electronics that are not needed. The drives can be in this
state with the system still awake.

Chapter 8 System BIOS
8.6.1.3 Suspend
Suspend is not supported in the Independent PM mode.
8.6.1.4 System OFF
When the system is turned Off but still plugged into a live AC outlet the NIC, ICH2, and I/O
components continue to receive auxiliary power in order to power-up as the result of a Magic
Packet™ being received over a network. Some NICs are able to wake up a system from Standby
in PM, most require their Windows/NT driver to reset them after one wake-up.
8.6.1.5 Waking Up in Independent PM
Activity of either of the following devices will cause the system to wake up with the screen
restored:
♦
♦
Keyboard
Mouse (if driver installed)
The hard drive will not spin up until it is accessed. Any hard drive access will cause it to wake up
and resume spinning. Since the BIOS returns to the currently running software, it is possible for
the drive to spin up while the system is in Standby with the screen blanked.
8.6.2 ACPI SUPPORT
These systems meet the hardware and firmware requirements for being ACPI compliant.
This system supports the following ACPI functions:
♦
♦
♦
♦
♦
♦
♦
PM timer
Power button
Power button override
RTC alarm
Sleep/Wake logic (S1,S3, S4 (Windows 2000), S5)
C1 state (Halt)
PCI Power Management Event (PME)
8.7
USB LEGACY SUPPORT
The BIOS ROM checks the USB port, during POST, for the presence of a USB keyboard. This
allows a system with only a USB keyboard to be used during ROM-based setup and also on a
system with an OS that does not include a USB driver.
On such a system a keystroke will generate an SMI and the SMI handler will retrieve the data
from the device and convert it to PS/2 data. The data will be passed to the keyboard controller and
processed as in the PS/2 interface. Changing the delay and/or typematic rate of a USB keyboard
though BIOS function INT 16 is not supported.

ASCII CHARACTER SET
B.1 INTRODUCTION
This appendix lists, in Table B-1, the 256-character ASCII code set including the decimal and
hexadecimal values. All ASCII symbols may be called while in DOS or using standard text-mode
editors by using the combination keystroke of holding the Alt key and using the Numeric Keypad
to enter the decimal value of the symbol. The extended ASCII characters (decimals 128-255) can
only be called using the Alt + Numeric Keypad keys.
NOTE: Regarding keystrokes, refer to notes at the end of the table. Applications may interpret
multiple keystroke accesses differently or ignore them completely.

KEYBOARD
C.1 INTRODUCTION
This appendix describes the HP/Compaq keyboard that is included as standard with the system
unit. The keyboard complies with the industry-standard classification of an “enhanced keyboard”
and includes a separate cursor control key cluster, twelve “function” keys, and enhanced
programmability for additional functions.
This appendix covers the following keyboard types:
♦
♦
Standard enhanced keyboard.
Space-Saver Windows-version keyboard featuring additional keys for specific support of the
Windows operating system.
♦
Easy Access keyboard with additional buttons for internet accessibility functions.
Only one type of keyboard is supplied with each system. Other types may be available as an
option.
NOTE: This appendix discusses only the keyboard unit. The keyboard interface is a
function of the system unit and is discussed in Chapter 5, Input/Output Interfaces.
Topics covered in this appendix include the following:

Appendix C Keyboard
C.2 KEYSTROKE PROCESSING
A functional block diagram of the keystroke processing elements is shown in Figure C-1. Power
(+5 VDC) is obtained from the system through the PS/2-type interface. The keyboard uses a
Z86C14 (or equivalent) microprocessor. The Z86C14 scans the key matrix drivers every 10 ms for
pressed keys while at the same time monitoring communications with the keyboard interface of
the system unit. When a key is pressed, a Make code is generated. A Break code is generated
when the key is released. The Make and Break codes are collectively referred to as scan codes. All
keys generate Make and Break codes with the exception of the Pause key, which generates a
Make code only.

Figure C–1. Keystroke Processing Elements, Block Diagram
When the system is turned on, the keyboard processor generates a Power-On Reset (POR) signal
after a period of 150 ms to 2 seconds. The keyboard undergoes a Basic Assurance Test (BAT)
that checks for shorted keys and basic operation of the keyboard processor. The BAT takes from
300 to 500 ms to complete.
If the keyboard fails the BAT, an error code is sent to the CPU and the keyboard is disabled until
an input command is received. After successful completion of the POR and BAT, a completion
code (AAh) is sent to the CPU and the scanning process begins.
The keyboard processor includes a 16-byte FIFO buffer for holding scan codes until the system is
ready to receive them. Response and typematic codes are not buffered. If the buffer is full (16
bytes held) a 17th byte of a successive scan code results in an overrun condition and the overrun
code replaces the scan code byte and any additional scan code data (and the respective key
strokes) are lost. Multi-byte sequences must fit entirely into the buffer before the respective
keystroke can be registered.

C.2.1 PS/2-TYPE KEYBOARD TRANSMISSIONS
The PS/2-type keyboard sends two main types of data to the system; commands (or responses to
system commands) and keystroke scan codes. Before the keyboard sends data to the system
(specifically, to the 8042-type logic within the system), the keyboard verifies the clock and data
lines to the system. If the clock signal is low (0), the keyboard recognizes the inhibited state and
loads the data into a buffer. Once the inhibited state is removed, the data is sent to the system.
Keyboard-to-system transfers (in the default mode) consist of 11 bits as shown in Figure C-2.

Figure C–2. PS/2 Keyboard-To-System Transmission, Timing Diagram
The system can halt keyboard transmission by setting the clock signal low. The keyboard checks
the clock line every 60 µs to verify the state of the signal. If a low is detected, the keyboard will
finish the current transmission if the rising edge of the clock pulse for the parity bit has not
occurred. The system uses the same timing relationships during reads (typically with slightly
reduced time periods).
The enhanced keyboard has three operating modes:
♦
♦
♦
Mode 1 - PC-XT compatible
Mode 2 - PC-AT compatible (default)
Mode 3 - Select mode (keys are programmable as to make-only, break-only, typematic)
Modes can be selected by the user or set by the system. Mode 2 is the default mode. Each mode
produces a different set of scan codes. When a key is pressed, the keyboard processor sends that
key’s make code to the 8042 logic of the system unit. The When the key is released, a release
code is transmitted as well (except for the Pause key, which produces only a make code). The
8042-type logic of the system unit responds to scan code reception by asserting IRQ1, which is
processed by the interrupt logic and serviced by the CPU with an interrupt service routine. The
service routine takes the appropriate action based on which key was pressed.

Appendix C Keyboard
C.2.2 USB-TYPE KEYBOARD TRANSMISSIONS
The USB-type keyboard sends essentially the same information to the system that the PS/2
keyboard does except that the data receives additional NRZI encoding and formatting (prior to
leaving the keyboard) to comply with the USB I/F specification (discussed in chapter 5 of this
guide).
Packets received at the system’s USB I/F and decoded as originating from the keyboard result in
an SMI being generated. An SMI handler routine is invoked that decodes the data and transfers
the information to the 8042 keyboard controller where normal (legacy) keyboard processing takes
place.

C.2.4 KEYS
All keys generate a Make code (when pressed) and a Break code (when released) with the
exception of the Pause key (pos. 16), which produces a Make code only. All keys with the
exception of the Pause and Easy Access keys are also typematic, although the typematic action
of the Shift, Ctrl, Alt, Num Lock, Scroll Lock, Caps Lock, and Ins keys is suppressed by the
BIOS. Typematic keys, when held down longer than 500 ms, send the Make code repetitively at a
10-12 Hz rate until the key is released. If more than one key is held down, the last key pressed
will be typematic.
C.2.4.1 Special Single-Keystroke Functions
The following keys provide the intended function in most applications and environments.
Caps Lock - The Caps Lock key (pos. 59), when pressed and released, invokes a BIOS
routine that turns on the caps lock LED and shifts into upper case key positions 40-49, 60-68,
and 76-82. When pressed and released again, these keys revert to the lower case state and the
LED is turned off. Use of the Shift key will reverse which state these keys are in based on the
Caps Lock key.
Num Lock - The Num Lock key (pos. 32), when pressed and released, invokes a BIOS routine
that turns on the num lock LED and shifts into upper case key positions 55-57, 72-74, 88-90,
100, and 101. When pressed and released again, these keys revert to the lower case state and the
LED is turned off.
The following keys provide special functions that require specific support by the application.
Print Scrn - The Print Scrn (pos. 14) key can, when pressed, generate an interrupt that initiates
a print routine. This function may be inhibited by the application.
Scroll Lock - The Scroll Lock key (pos. 15) when pressed and released, invokes a BIOS
routine that turns on the scroll lock LED and inhibits movement of the cursor. When pressed and
released again, the LED is turned off and the function is removed. This keystroke is always
serviced by the BIOS (as indicated by the LED) but may be inhibited or ignored by the
application.
Pause - The Pause (pos. 16) key, when pressed, can be used to cause the keyboard interrupt to
loop, i.e., wait for another key to be pressed. This can be used to momentarily suspend an
operation. The key that is pressed to resume operation is discarded. This function may be ignored
by the application.
The Esc, Fn (function), Insert, Home, Page Up/Down, Delete, and End keys operate at the
discretion of the application software.

C.2.4.2
Multi-Keystroke Functions
Shift - The Shift key (pos. 75/86), when held down, produces a shift state (upper case) for keys in
positions 17-29, 30, 39-51, 60-70, and 76-85 as long as the Caps Lock key (pos. 59) is toggled
off. If the Caps Lock key is toggled on, then a held Shift key produces the lower (normal) case
for the identified pressed keys. The Shift key also reverses the Num Lock state of key positions
55-57, 72, 74, 88-90, 100, and 101.
Ctrl - The Ctrl keys (pos. 92/96) can be used in conjunction with keys in positions 1-13, 16, 17-
34, 39-54, 60-71, and 76-84. The application determines the actual function. Both Ctrl key
positions provide identical functionality. The pressed combination of Ctrl and Break (pos. 16)
results in the generation of BIOS function INT 1Bh. This software interrupt provides a method of
exiting an application and generally halts execution of the current program.
Alt - The Alt keys (pos. 93/95) can be used in conjunction with the same keys available for use
with the Ctrl keys with the exception that position 14 (SysRq) is available instead of position 16
(Break). The Alt key can also be used in conjunction with the numeric keypad keys (pos. 55-57,
72-74, and 88-90) to enter the decimal value of an ASCII character code from 1-255. The
application determines the actual function of the keystrokes. Both Alt key positions provide
identical functionality. The combination keystroke of Alt and SysRq results in software interrupt
15h, AX=8500h being executed. It is up to the application to use or not use this BIOS function.
The Ctrl and Alt keys can be used together in conjunction with keys in positions 1-13, 17-34, 39-
54, 60-71, and 76-84. The Ctrl and Alt key positions used and the sequence in which they are
pressed make no difference as long as they are held down at the time the third key is pressed. The
Ctrl, Alt, and Delete keystroke combination (required twice if in the Windows environment)
initiates a system reset (warm boot) that is handled by the BIOS.
C.2.4.3 Windows Keystrokes
Windows-enhanced keyboards include three additional key positions. Key positions 110 and 111
(marked with the Windows logo
) have the same functionality and are used by themselves or
in combination with other keys to perform specific “hot-key” type functions for the Windows
operating system. The defined functions of the Windows logo keys are listed as follows:

C.2.6 SCAN CODES
The scan codes generated by the keyboard processor are determined by the mode the keyboard is
operating in.
♦
♦
Mode 1:
In Mode 1 operation, the keyboard generates scan codes compatible with 8088-
/8086-based systems. To enter Mode 1, the scan code translation function of the keyboard
controller must be disabled. Since translation is not performed, the scan codes generated in
Mode 1 are identical to the codes required by BIOS. Mode 1 is initiated by sending command
F0h with the 01h option byte. Applications can obtain system codes and status information by
using BIOS function INT 16h with AH=00h, 01h, and 02h.
Mode 2:
Mode 2 is the default mode for keyboard operation. In this mode, the 8042 logic
translates the make codes from the keyboard processor into the codes required by the BIOS.
This mode was made necessary with the development of the Enhanced III keyboard, which
includes additional functions over earlier standard keyboards. Applications should use BIOS
function INT 16h, with AH=10h, 11h, and 12h for obtaining codes and status data. In Mode
2, the keyboard generates the Break code, a two-byte sequence that consists of a Make code
immediately preceded by F0h (i.e., Break code for 0Eh is “F0h 0Eh”).
♦
Mode 3:
Mode 3 generates a different scan code set from Modes 1 and 2. Code
translation must be disabled since translation for this mode cannot be done.

D.2 FUNCTIONAL DESCRIPTION
The Intel PRO/100+ and the PRO/100 S Management Adapters are based on the Intel 82559 and
82550 Ethernet Controllers (respectively) supported by firmware in flash ROM (see figure
below). Each adapter can operate in half- or full-duplex modes and provides auto-negotiation of
both mode and speed. Half-duplex operation features an Intel-proprietary collision reduction
mechanism while full-duplex operation follows the IEEE 802.3x flow control specification.
Transmit and receive FIFOs of three kilobytes each reduce the chance of overrun while waiting
for bus access. Each card includes an on-board 5/3.3 VDC regulator circuit and WOL connector
in support of Wake-On-LAN functionality.

Key features of these adapters include:
♦
♦
♦
♦
♦
♦
3-KB transmit and 3-KB receive FIFOs
PCI ver. 2.2 compliant (PME- support)
Dual-mode support with auto-switching between 10BASE-T and 100BASE-TX
Both APM and ACPI power management compliant
D0-D3 power state wake event support
Boot ROM with PXE and RPL support
The 82559 and 82550 controllers feature high and low priority queues and provides priority-
packet processing for networks that support that feature. The controller’s micro-machine
processes transmit and receive frames independently and concurrently. Receive runt (undersized)
frames are not passed on as faulty data but discarded by the controller, which also directly handles
such errors as collision detection or data under-run. An EEPROM is used to store identification,
configuration, and connection parameters.
The 82550 controller provides all the functionality of the 82559 plus IP security (IPSEC) support
through a hardware accelerator engine.

D.2.1 AOL FUNCTION
The adapter’s Alert-On-LAN (AOL) function provides a AOL-compliant system unit with the
ability to communicate system status to a management console, even while the system is powered
down. When installed in an AOL-compliant system, the adapter receives alert messages from the
system’s south bridge over the PCI bus. Each alert message decoded by the adapter results in a
pre-constructed status message being transmitted over the network to a management console.
Alert-On-LAN functionality occurs independent of software, driver, or even processor
intervention. The adapter can report following conditions:
♦
♦
♦
♦
♦
♦
System tampering – Removal of the chassis cover
BIOS failure – System fails to boot successfully
OS problem – System fails to load operating system after boot
Missing/faulty processor – Processor fails to fetch first instruction
Thermal condition – High temperature detected in system
Heartbeat – Indication of system’s presence on the network (sent approximately every 30
seconds)
NOTE: The system unit must be plugged into a live AC outlet for the AOL function to
be operative. Controlling a system unit’s power through an AC outlet strip will,
when the strip is turned off, disable AOL functionality.
The AOL implementation requirements are as follows:
1. System unit featuring the 810, 810e, 820, or 850 (or later) chipset.
2. Intel PRO/100+ Management Adapter Driver 3.1 or later (available from HP/Compaq).
3. Client-side utility agent software (available from HP/Compaq).
4. Management console running one of the following:
a. HP OpenView Network Node Manager 6.x.
b. Intel LANDesk Client Manager.
c. Compaq Insight Manager.
D.2.2 WAKE UP FUNCTIONS
The adapter provides two types of wake-up signaling: the PME- signal and the WOL signal.
The adapter provides PME- signal support for systems compliant with PCI ver. 2.2. The detection
of any wake event results in the adapter’s assertion of the PME- signal, which can be used by the
system unit to initiate the power-up sequence. System software is responsible for the clearing the
PME- signal.
The adapter also includes a WOL interface for systems supporting that method of wake-up. The
adapter asserts the WOL signal for 50 milliseconds upon detection of a Magic Packet. The WOL
signal is routed to the system unit (through a three-conductor cable connection) for initializing a
power-up sequence.

Appendix D Compaq/Intel Network Interface Controller Adapters
D.2.3 IPSEC FUNCTION
The 82550 controller used on the Intel PRO/100 S Management Adapter includes an encryption
engine that provides on-the-fly encryption and/or authentication of transmit data without
additional use of system memory and software. This function, referred to as IP security (IPSEC),
uses a configurable algorithm and established Data Encryption Standards (DES) to provide high
performance (full transmission rate) encryption. Received IPSEC data frames are re-submitted to
the controller for processing and then returned to the driver.
Key features of IPSEC support include:
♦
♦
♦
Encryption capability of 56-bit DES to 168-bit 3DES
Out-of-order processing of non-security transmit frames during security mode
SHA-1 and MD-5 authentication with optional HMAC cryptographic hashing

D.3 POWER MANAGEMENT SUPPORT
These adapters support APM and ACPI power management environments as well as the Wired-
for-Management (WfM) and Wake-On-LAN (WOL) standards. The adapter is designed to be
powered up as long as the system unit is plugged into a live AC outlet to provide system “wake-
up” functionality. Power is provided by either the auxiliary 3.3 VDC power rail of the PCI bus
(when installed in systems compliant with PCI ver. 2.2) or by auxiliary 5 VDC through the WOL
connector.
NOTE: Controlling a system unit’s power through an AC outlet strip will, with the
strip turned off, disable wake-up functionality.
D.3.1 APM ENVIRONMENT
The Advanced Power Management (APM) functionality of system wake up is implemented
through the system’s APM-compliant BIOS and Magic Packet-compliant hardware. This
environment is not dependent on operating system (OS) intervention allowing a unit plugged into
a live AC outlet to be turned on remotely over the network (i.e., “remote wake-up”) even if the OS
has not been installed. In APM mode the controller will respond upon receiving a Magic Packet,
which is a packet where the node’s address is repeated 16 times. Upon Magic Packet reception,
the adapter asserts the PME- signal (on the PCI bus) resulting in the system unit’s power control
logic turning on the system and initiating the boot sequence. After the boot sequence the BIOS
clears the PME- signal so that subsequent wake up events will be detected.
D.3.2 ACPI ENVIRONMENT
The Advanced Configuration and Power Interface (ACPI) functionality of system wake up is
implemented through an ACPI-compliant OS (such as Windows NT 5.0) and is the default power
management mode. The following wake up events may be individually enabled/disabled through
the software driver supplied with the adapter:
♦
♦
♦
♦
♦
♦
♦
♦
♦
Magic Packet – Packet with node address repeated 16 times in data portion.
Individual address match – Directed acket with matching user-defined byte mask.
Multicast address match – Directed packet with matching user-defined sample frame.
ARP (address resolution protocol) packet
Flexible packet filtering – Packets that match defined CRC signature.
NBT query (under Ipv4)
IPX Diagnostic
TCO packet
VLAN Type
When an enabled event is received the controller asserts the PME- signal that is used to initiate the
wakeup sequence.
