3. Processor and Chipset
The Server Works* ServerSet III HE-SL chipset provides the 36-bit address, 72-bit data (64-bit
data + 8-bit ECC) processor host bus interface, operating at 133 MHz in the AGTL signaling
environment. The HE-SL North Bridge provides an integrated memory controller, the interface to
32-bit, 33-MHz Rev 2.2 compliant PCI bus, and two Inter-Module Bus interfaces. The Inter-
Module Bus (IMB) provides the interface to two 64-bit, 66-MHz Rev 2.2 compliant PCI buses via
the CIOB20.
The SDS2 DP Server Board directly supports up to 6 GB of ECC memory, using six PC-133-
compliant registered SDRAM DIMMs. The ECC implementation in the HE-SL can detect and
correct single-bit errors, and it can detect multiple-bit errors.
3.1 Processors
The SDS2 Server Board supports two Intel® Pentium® III processors in the Socket 370 FCPGA2
package. If two processors are installed, both processors must be of identical revisions with the
same core voltage and speed for the bus and core. If one processor is installed, an AGTL
terminator module must be installed in the other socket. The support circuitry on the Server
Board consists of the following:
·

Notes:
·
All processor sockets must be populated with either a processor or a terminator module.
The BMC will not allow DC power to be applied to the system unless both processor
sockets contain a properly seated processor or terminator module.
·
·
Processors should be populated in the sequential order. In other words, processor
socket #1 should be populated before processor socket #2.
BIO 50 (released on FAB 5) supports the tB1 stepping, CPUID 06B4. These processors
are being evaluated for addition to supported processor list. The current Intel support
web site has the latest supported processor list for SDS2:

3.1.1
Processor Voltage Regulator Module (VRM)
The SDS2 Server Board has dual, on board, RMcircuitry to support the two processors. The
circuit is compliant with the VRM8.5 specification and provides a maximum of 60A, which will
support the currently available processors and future releases of the Pentium III processors.
The board hardware and the BMC read the processor VID (Voltage Identification) bits for each
processor before turning on the power to the processors (VRMs). If the VIDs of the two
processors are not identical, then the BMC will not turn on the VRMs and a beep code is
generated. Table 30. BMC Beep Codes lists all of the error codes.
3.2 Memory Subsystem
The SDS2 Server Board supports up to six DIMM sockets for a maximum memory capacity of 6
GB using 1 GB DIMMs. The DIMM organization is x72, which includes 8 ECC check bits. ECC
from the DIMMs is passed through to the processor front side bus.
The SDRAM interface runs at the same frequency as the processor bus. The memory controller
supports 2-way interleaved SDRAM, memory scrubbing, single-bit error correction, and multiple-
bit error detection. Memory can be implemented with either single-sided (one row) or double-
sided (two row) DIMMs.
·
·
·
·
·
Only registered PC-133 compliant memory is supported
Support is 2-way interleaved SDRAM and requires two DIMMs to be installed per bank.
ECC single-bit error correction and multiple-bit error detection
Maximum memory capacity of 6 GB
Minimum memory capacity of 128 MB
Note:Memory interleaving is a way to increase memory performance by allowing the system to
access multiple memory modules simultaneously, rather than sequentially, in a similar fashion to
Hard Drive striping. Interleaving can only take place between identical memory modules.

3.3 Chipset
The Server Works* ServerSet III HE-SL chipset provides an integrated I/O bridge and memory
controller and a flexible I/O subsystem core (PCI), targeted for multiprocessor systems and
standard high-volume servers. The Server Works* ServerSet III chipset consists of the three
components listed below:
·
CNB20HE-SL: Champion North Bridge. The HE-SL North Bridge is responsible for
accepting access requests from the host (processor) bus and for directing those
accesses to memory or to one of the PCI buses. The HE-SL monitors the host bus,
examining addresses for each request. Accesses may be directed to a memory request
queue, for subsequent forwarding to the memory subsystem, or to an outbound request
queue, for subsequent forwarding to one of the PCI buses. The HE-SL also accepts
inbound requests from the CIOB20 and the legacy PCI bus. The HE-SL is also
responsible for generating the appropriate controls to control data transfer to and from
the memory.
·
·
CIOB20: Champion I/O Bridge. The CIOB20 provides the interface for two 64-bit, 66-
MHz Rev. 2.2 compliant PCI bus. The CIOB is both master and target on both PCI
buses.
CSB5: South Bridge. The CSB5 controller has several components. It provides the
interface for a 32-bit, 33-MHz Rev. 2.2-compliant PCI bus. The CSB5 can be both a
master and a target on that PCI bus. The CSB5 also includes a USB controller and an
IDE controller. The CSB5 is also responsible for much of the power management
functions, with ACPI control registers built in. The CSB5 also provides a number of GPIO
pins and has the LPC bus to support low-speed legacy I/O.

CNB20HE-SL Champion North Bridge
The Champion North Bridge Rev 2.0 High End Super Lite (CNB20HE-SL) is the third generation
product in the Server Works Champion North Bridge Technology. The HE-SL is a 644-pin ball-
grid array (BGA) device and uses the proven components of previous generations like the
Pentium Pro Bus interface unit, the PCI interface unit, and the SDRAM memory interface unit. In
addition, the HE-SL incorporates a proprietary Intra Module Bus (IMBus) Interface. The IMBus
interface enables the HE-SL to directly interface with the CIOB20 through its two unidirectional
16-bit wide data busses with parity support. The HE-SL also increases the main memory
interface bandwidth and maximum memory configuration with a 144-bit wide memory interface.
The HE-SL integrates three main functions:
·
·
An integrated high-performance main memory subsystem
An IMBus interface that provides a high-performance data flow path between the Pentium
Pro bus and the I/O subsystem
·
A PCI interface which provides an interface to the compatibility PCI bus segment and the
CSB5 (South Bridge).
Other features provided by the HE-SL include the following:
·
·
·
·
·

CIOB20 Champion I/O Bridge
The Champion I/O Bridge (CIOB) is a 352-pin ball-grid array device and provides an integrated
I/O bridge that provides a high-performance data flow path between the IMBus and the 64-bit I/O
subsystem. This subsystem supports peer 64-bit PCI segments. Because it has multiple PCI
interfaces, the CIOB can provide large and efficient I/O configurations. The CIOB functions as
the bridge between the IMBus and the multiple 64-bit PCI I/O segments.
The IMBus interface can support 512 MB/s of data bandwidth in both the upstream and
downstream direction simultaneously.
The internal PCI arbiter implements the Least Recently used algorithm to grant access to
requesting masters.

4.1.2.4
Zero Channel RAID (ZCR) Capable PCI Slot 6
The SDS2 Server Board supports zero-channel RAID controller on PCI Slot 6. This add-in card
leverages the on-board SCSI controller along with its own built-in intelligence to provide a
complete RAID controller subsystem on-board. If a specified zero-channel RAID card is
installed, then SCSI interrupts are routed to the RAID card instead of PCI interrupt controller and
the host-based I/O device is effectively hidden from the system. The SDS2 Server Board uses
an implementation commonly referred to as “RAIDIOS” to support this feature.
Note: Zero Channel Raid Cards (ZCR) cards are only supported on PCI slot 6.
Note: Intel zero channel raid cards SRCMR and SRCMRU are not supported on SDS2.
4.2 Ultra160 SCSI
The SDS2 Server Board provides an embedded dual-channel SCSI bus through the use of the
Adaptec*’s AIC-7899W SCSI controller. The AIC-7899W controller contains two independent
SCSI controllers that share a single 64-bit, 66-MHz PCI bus master interface as a multifunction
device, packaged in a 456-pin BGA. Internally, each controller is identical, capable of operations
using either 16-bit SE or LVD SCSI providing 40 MBps (Ultra-wide SE), 80 MBps (Ultra 2), or 160
MBps (Ultra160). Each controller has its own set of PCI configuration registers and SCSI I/O
registers. The SDS2 Server Board supports disabling of the on-board SCSI controller through
the BIOS setup menu.
The SDS2 Server Board provides active terminators, termination voltage, re-settable fuse, and
protection diode for both SCSI channels. The SCSI BIOS setup menu (CNTRL-A) provides the
ability to enable or disable the on-board terminators for both channels A and B.
4.3 Video Controller
The SDS2 Server Board provides an ATI* RAGE XL PCI graphics accelerator, along with video
SDRAM and support circuitry for an embedded SVGA video subsystem. The ATI* RAGE XL chip
contains a SVGA video controller, clock generator, 2D and 3D engine, and RAMDAC in a 272-pin
PBGA. Two 2 MB SDRAM chips provide 4 MB of video memory. The SVGA subsystem supports
a variety of modes, up to 1024 x 768 resolution in 8/16/24/32 bpp modes under 2D and up to 800
x 600 resolution in 8/16/24/32 bpp modes under 3D. It also supports both CRT and LCD
monitors at up to 100 Hz vertical refresh rate. The SDS2 Server Board provides a standard 15-
pin VGA connector.

4.5 CSB5 South Bridge (PCI-to-LPC Bridge, IDE, USB)
The CSB5 is a multi-function PCI device, housed in a 256-pin BGA device, providing PCI-to-LPC
bridge, PCI IDE interface, PCI USB controller, and power management controller. Each function
within the CSB5 has its own set of configuration registers. Once configured, each appears to the
system as a distinct hardware controller sharing the same PCI bus interface.
In the SDS2 Server Board implementation, the primary role of the CSB5’ is to provide the
gateway to all PC-compatible I/O devices and features. The SDS2 uses the following CSB5
features:
·
·
·
·
·
·
·
·
PCI bus interface
LPC bus interface
IDE interface, with Ultra DMA 100 capability
Universal Serial Bus (USB) interface
PC-compatible timer/counter and DMA controllers
APIC and 8259 interrupt controller
Power management
General purpose I/O
Following are descriptions of how each supported feature is implemented in SDS2.
4.5.1 PCI Bus Interface
The CSB5 fully implements a 32-bit PCI master/slave interface, in accordance with the PCI
Local Bus Specification, Revision 2.2. On the SDS2 Server Board, the PCI interface operates at
33 MHz, using the 5 V signaling environment.
4.5.2
PCI Bus Master IDE Interface
The CSB5 acts as a PCI-based Fast IDE controller that supports programmed I/O transfers and
bus master IDE transfers. The CSB5 supports two IDE channels, supporting two drives each
(drives 0 and 1). The FAB 5 (PBA A58285-502) SDS2 Server Board supports two IDE channels
through the standard 40-pin (2x20) connector. Note FAB 4 boards (PBA A58285-402 and –403)
supported only one IDE channel.
The SDS2 IDE interface supports the following features:

4.5.3
USB Interface
The CSB5 contains a USB controller and four USB hubs. The USB controller moves data
between main memory and the four USB connectors.
The SDS2 Server Board provides a three external USB connector interface on the rear I/O. One
additional USB is supported internally through a 10-pin header (2 X 5) that can be cabled to a
front panel board. All four ports function identically and with the same bandwidth. The USB
Specification, Revision 1.1, defines the external connector. Table 68. 10-pin USB Connection
Header (2 x 5) Pin-out.
4.5.4
Compatibility Interrupt Control
The CSB5 provides the functionality of two 82C59 PIC devices for ISA-compatible interrupt
handling.
4.5.5
APIC
The CSB5 integrates a 32-entry I/O APIC that is used to distribute 32 PCI interrupts. It also
includes an additional 16-entry I/O APIC for the distribution of legacy ISA interrupts.
4.5.6
Power Management
One of the embedded functions of CSB5 is a power management controller. The SDS2 Server
Board uses this to implement ACPI-compliant power management features. The SDS2 supports
sleep states S0, S1, S4, and S5.
4.5.7
General Purpose Input and Output Pins
The CSB5 provides a number of general purpose input and output pins. Many of these pins have

BIOS Flash
The SDS2 Server Board incorporates a Fairchild* 29LV008B 8Mbit Flash ROM. The flash device
is connected through the X-bus of the CSB5.
4.7 Interrupt Routing
The SDS2 Server Board interrupt architecture implements both PC-compatible PIC mode and
APIC mode interrupts through the use of the integrated I/O APICs in the CSB5.
4.7.1
Legacy Interrupt Routing
For PC-compatible mode, the CSB5 provides two 82C59-compatible interrupt controllers. The
two controllers are cascaded with interrupt levels 8-15 entering on level 2 of the primary interrupt
controller (standard PC configuration). A single interrupt signal is presented to the processors, to
which only one processor will respond for servicing. The CSB5 contains configuration registers
that define which interrupt source logically maps to I/O APIC INTx pins.
Interrupts, both PCI and IRQ types, are handled by the CSB5. The CSB5 then translates these to
the APIC bus. The numbers in the table below indicate the CSB5 PCI interrupt input pin to which
the associated device interrupt (INTA, INTB, INTC, INTD) is connected. The CSB5’s I/O APIC
exists on the I/O APIC bus with the processors.

4.7.2
APIC Interrupt Routing
For APIC mode, the SDS2 interrupt architecture incorporates three Intel I/O APIC devices to
manage and broadcast interrupts to local APICs in each processor. The I/O APICs monitor each
interrupt on each PCI device including PCI slots in addition to the ISA compatibility interrupts IRQ
(0-15). When an interrupt occurs, a message corresponding to the interrupt is sent across a
three-wire serial interface to the local APICs. The APIC bus minimizes interrupt latency time for
compatibility interrupt sources. The I/O APICs can also supply greater than 16 interrupt levels to
the processor(s).
4.7.3
Serialized IRQ Support
The SDS2 Server Board supports a serialized interrupt delivery mechanism. Serialized IRQs
(SERIRQ) consists of a start frame, a minimum of 17 IRQ / data channels, and a stop frame.
Any slave device in the quiet mode may initiate the start frame. While in the continuous mode,
the start frame is initiated by the host controller.
4.7.4
IRQ Scan for PCIIRQ
The IRQ / data frame structure includes the ability to handle up to 32 sampling channels with the
standard implementation using the minimum 17 sampling channels. The SDS2 Server Board
has an external PCI interrupt serializer for PCIIRQ scan mechanism of CSB5 to support 16
PCIIRQs.

5.1 Sahalee Baseboard Management Controller
The Sahalee BMC contains a 32-bit RISC processor core and associated peripherals used to
monitor the system for critical events. The Sahalee BMC, packaged in a 156-pin BGA, monitors
all power supplies, including those generated by the external power supplies and those regulated
locally on the Server Board.
The Sahalee BMC also monitors SCSI termination voltage, fan tachometers for detecting a fan
failure, and system temperature. Temperature is measured on each of the processors and at
locations on the Server Board away from the fans. When any monitored parameter is outside the
defined thresholds, the Sahalee BMC logs an event in the System Event Log (SEL).
Management controllers and sensors communicate on the I2C-based Intelligent Platform
Management Bus. Attached to one of its private I2C bus is Hecetas, which is an ADM1026. The
ADM1026 is a versatile Systems Monitor ASIC. Some of its features include:

5.2 System Reset Control
Reset circuitry on the SDS2 Server Board looks at resets from the front panel, CSB5, ITP, and
processor subsystem to determine proper reset sequencing for all types of reset. The reset logic
is designed to accommodate a variety of ways to reset the system, which can be divided into the
following categories:
·
·
·
Power-up reset
Hard reset
Soft (programmed) reset
The following subsections describe each category of reset.
5.2.1 Power-up Reset
When the system is disconnected from AC power, all logic on the Server Board is powered off.
When a valid input (AC) voltage level is provided to the power supply, 3.3 V standby power is
applied to the Server Board. A power monitor circuit on 3.3 V standby asserts
N_RST_BMCRST_L, causing the BMC to reset. The BMC is powered by 3.3 V standby and
monitors and controls key events in the system related to reset and power control.
After the system is turned on, the power supply asserts the N_PWRGD+00 signal after all
voltage levels in the system have reached valid levels. The BMC receives N_PWRGD+00 and
after approximately 500 ms it asserts N_RST_P6_PWRGOOD, which indicates to the
processors and CSB5 that the power is stable. Upon N_RST_P6_PWRGOOD assertion, the
CSB5 will toggle PCI reset.
5.2.2
Hard Reset
A hard reset can be initiated by resetting the system through the front panel switch. During the
reset, the Sahalee BMC de-asserts the N_RST_P6_PWRGOOD signal. After approximately 500
ms, it is reasserted, and the Power-up Reset sequence is done.
The Sahalee BMC is not reset by a hard reset. It may be reset at power-up.
5.2.3
Soft Reset
A soft reset causes the processors to begin execution in a known state without flushing the
caches or internal buffers. The keyboard controller located in the SIO or by the CSB5 can
generate soft resets. The output of the SIO (N_KBD_PINITL) is input to the CSB5.
5.3 Intelligent Platform Management Buses
Management controllers and sensors communicate on the I2C-based Intelligent Platform
Management Bus. A bit protocol defined by the I2C Bus Specification, and a byte-level protocol
defined by the Intelligent Platform Management Bus Communications Protocol Specification,
provide an independent interconnect for all devices operating on this I2C bus. The IPMB extends
throughout the Server Board and system chassis. An added layer in the protocol supports
transactions between multiple servers on inter-chassis I2C bus segments.

5.4 Error Reporting
This section documents the types of system bus error conditions monitored by the SDS2 Server
Board.
5.4.1
Error Sources and Types
One of the major requirements of server management is to correctly and consistently handles
system errors. System errors on the SDS2, which can be disabled and enabled individually, can
be categorized as follows:
·
·
·
·
PCI bus
Processor bus errors
Memory single- and multi-bit errors
General server management sensors, managed by the Sahalee BMC
5.4.2
PCI Bus Errors
The PCI bus defines two error pins, PERR# and SERR#, for reporting PCI parity errors and
system errors, respectively. In the case of PERR#, the PCI bus master has the option to retry
the offending transaction, or to report it using SERR#. All other PCI-related errors are reported by
SERR#. SERR# is routed to NMI if enabled by BIOS.
5.4.3
Intel® Pentium® III Processor Bus Errors
The HE-SL supports all the data integrity features supported by the Pentium Pro bus including
Address, Request and Response parity. The HE-SL always generates ECC data while it is driving
the processor data bus although data bus ECC can be disabled or enabled by BIOS (enabled by
default). The HE-SL generates MIRQ# on SBEs (Single-bit errors) and generates SALERT# on
32

Intel® Server Board SDS2
Server Management
uncorrectable errors. In addition, the HE-SL can generate BERR# on unrecoverable ECC errors
detected on the processor bus. Unrecoverable errors are routed to NMI by BIOS.
5.4.4
Memory Bus Errors
The HE-SL is programmed to generate an SMI on single-bit data errors in the memory array if
ECC memory is installed. The HE-SL performs the scrubbing. The SMI handler simply records the
error and the DIMM location to the System Event Log. Double-bit errors in the memory array are
mapped to SMI because the Sahalee BMC cannot determine the location of the bad DIMM.
5.4.5
ID LED
The blue “ID LED”, located at the back edge of the Server Board near NIC2, is used to help locate
a given server platform requiring service when installed in a multi-system rack. The LED is lit when
the front panel ID button is pressed and is turned off when the button is pressed again.
5.5 ACPI
The Advance Configuration and Power Interface (ACPI)-aware operating system can place the
system into a state where the hard drive spin down, the system fans stop, and all processing is
halted. In this state, the power supply is still on and the processors still dissipate some power,
such that the power supply fan and processor fans continue to run.
Note:ACPI requires an operating system that supports this feature.
The sleep states discussed below are defined as:
·
·
S0: Normal running state
S1: Processor sleep state. No content is lost in this state and the processor caches
maintain coherency
·
S4: Hibernate or Save to Disk. The memory and machine state are saved to disk.
Pressing the power button or another wakeup event restores the system state from disk
and resumes normal operation. This assumes that no hardware changes were made to
the system while it was off
·
S5: Soft off. Only the RTC section of the chip set and the BMC are running in this state
The SDS2 Server Board supports sleep states s0, s1, s4, and s5. When the Server Board is
operating in ACPI mode, the operating system retains control of the system and the operating
system policy determines the entry methods and wake up sources for each sleep state. Sleep
entry and wake-up event capabilities are provided by the hardware but are enabled by the OS.
5.6 AC Link Mode
The AC link mode allows the system to monitor its AC input power so that if AC input power is lost
and then restored, the system returns to one of the following pre-selected settings:
·
·
·
Power On
Last State (Factory Default Setting)

BIOS
6. BIOS
This section describes the BIOS-embedded software for the SDS2 server board. The BIOS
contains standard PC-compatible basic input/output (I/O) services, system-specific hardware
configuration routines and register default settings that are embedded in Flash read-only
memory (ROM). This document also describes BIOS support utilities (not ROM-resident) that
are required for system configuration and flash ROMupdate. The BIOS is implemented as
firmware that resides in the flash ROM.
The term BIOS, as used in the context of this document, refers to the system BIOS, the BIOS
Setup, and option ROMs for on-board peripheral devices that are contained in the system flash.
The system BIOS controls basic system functionality using stored configuration values. The
terms flash ROM, system flash, and BIOS flash may be used interchangeably in this document.
BIOS Setup is a Flash ROM-resident setup utility that provides the user with control of
configuration values stored in battery-backed CMOS configuration RAM. BIOS options can also
be set utilizing the System Setup Utility (SSU). Operation of the SSU is discussed in a separate
document. BIOS Setup is closely tied with the system BIOS and is considered a part of BIOS.
Phoenix* Phlash (PHLASH.EXE) is used to load areas of flash ROMwith Setup, BIOS, and other
code/data.
The following is the breakdown of the SDS2 product ID string.
·
·
·
·
·
4-byte board ID, ‘SDS2’
1-byte board revision, starting from ‘0’
3-byte OEM ID, ‘86B’ for standard BIOS
4-byte build number
1-3 bytes describing build type (D for development, A for Alpha, B for Beta, Pxx for
production version xx)
·
·
6-byte build date in yymmdd format

6.1 System BIOS
The system BIOS is the core of the flash ROM-resident portion of the BIOS. The system BIOS
provides standard PC-BIOS services and support for industry standards, such as the Advanced
Configuration and Power Interface Specification, Revision 1.0b and Wired for Management
Baseline Specification, Revision 2.0.
In addition, the system BIOS supports the following features.

6.2 BIOS Error Handling
This section defines how errors are handled by the system BIOS on the SDS2 server board.
Also discussed are the role of BIOS in error handling, and the interaction between the BIOS,
platform hardware, and server management firmware with regard to error handling. In addition,
error-logging techniques are described and beep codes for errors are defined.
6.2.1
Error Sources and Types
One of the major requirements of server management is to correctly and consistently handles
system errors. System errors, which can be disabled and enabled individually or as a group, can
be categorized as follows:
·
·
·
·
PCI bus
Memory correctable- and uncorrectable errors
Sensors
Processor internal error, bus/address error, thermal trip error, temperatures and
voltages, and GTL voltage levels
The BMC manages the sensors. It is capable of receiving event messages from individual
sensors and logging system events.
6.2.2
Handling and Logging System Errors
This section describes actions taken by the SMI handler with respect to the various categories of
system errors. It covers the events logged by the BIOS and the format of data bytes associated
with those events. The BIOS is responsible for monitoring and logging certain system events.
The BIOS sends a platform event message to BMC to log the event. Some of the errors, such
as processor failure, are logged during early POST and not through the SMI handler.
6.2.2.1
Logging Format Conventions
The BIOS complies with the Intelligent Platform Management Interface Specification, Revision
1.5. The BIOS always uses system software ID within the range 00h-1Fh to log errors. As a
result, the Generator ID byte is an odd number in the range 01h-3fh. OEM user binary should use
software IDs of 1. The Software ID allows external software to find the origin of the event
message.

6.2.3
SMI Handler
The SMI handler handles and logs system level events that are not visible to the server
management firmware. The SMI handler, even those that are normally considered to generate an
NMI, preprocesses all system errors. The SMI handler sends a command to the BMC to log the
event and provides the data to be logged, a Set NMI Source command to indicate BIOS as the
source of the NMI, and a BIOS LCD command to display the LCD and LED message(s). A
correctable memory error does not generate an SMI. Correctable and uncorrectable memory
errors are handled and logged by the BMC.
6.2.3.1
PCI Bus Error
The PCI bus defines two error pins, PERR# and SERR#, for reporting PCI parity errors and
system errors, respectively.
6.2.3.2
Intel® Pentium® III Processor Bus Error
In the case of irrecoverable errors on the host processor bus, proper execution of SMI handler
cannot be guaranteed and SMI handler cannot be relied upon to log such conditions. The BIOS
SMI handler records the error to the System Event Log only if the system has not experienced a
catastrophic failure that compromises the integrity of the SMI handler. The BIOS always enables
the error correction and detection capabilities of the processors by setting appropriate bits in
processor model specific register (MSR).

BIOS
6.2.3.3
Memory Bus Error
The BMC monitors and logs memory errors. The BIOS will configure the hardware to notify the
BMC on correctable and uncorrectable memory errors. Uncorrectable errors generate an SMI to
stop the system and prevent propagation of the error. The BMC will query the hardware for error
information when notified.
6.2.3.4
System Limit Error
The BMC monitors system operational limits. It manages the A/D converter, defining voltage and
temperature limits as well as fan sensors and chassis intrusion. Any sensor values outside of
specified limits are handled by the BMC and there is no need to generate an SMI to the host
processor.
6.2.3.5
Processor Failure
The BIOS detects processor BIST failure and logs this event. The first OEM data byte field in the
log can identify the failed processor. For example, if processor 0 fails, the first OEM data byte is
0. The BIOS depends upon BMC to log the watchdog timer reset event.
6.2.3.6
Boot Event
The BIOS downloads the system date and time to the BMC during POST and logs a boot event.
This does not indicate an error, and software that parses the event log should treat it as such.
6.2.3.7
Chipset Failure
The BIOS detects the chipset (CNB2.0HE-SL and CIOB20) failure and logs this event. The
chipset error generates an SMI.
6.2.4
Firmware (BMC)
The BMC implements the logical System Event Log (SEL) device as specified in the Intelligent
Platform Management Interface Specification, Version 1.5. The SEL is accessible via all BMC
transports. This allows the System Event Log information to be accessed while the system is
down via out-of-band interfaces.
6.2.4.1
Sensor Number and Types Codes
The BIOS generates a POST error message when the System Event Log is full. This warning
will not inhibit the system from booting if halt on Post Error code is disabled in the BIOS Setup in
the Advanced menu.
Sensor Name, Sensor number and Sensor type for the SDS2 platform are listed in the following

Timestamp Clock
The BMC maintains a four-byte internal timestamp clock used by the System Event Log and
Sensor Data Record subsystems. This clock is incremented once per second and is read and
set using the Get SEL Time and Set SEL Time commands, respectively. The Get SDR Time
command can also be used to read the timestamp clock.
The BMC has direct access the system real-time clock. This allows the BMC to automatically
synchronize the SEL/SDR timestamp clock to the real-time clock time on BMC startup. The
BMC periodically reads the real-time clock to maintain synchronization even when software
asynchronously changes the value. In addition to this, the BIOS send a timestamp to the BMC
using Set SEL Time command during POST.

The following table contains the POST codes displayed during the boot process. A beep code is
a series of individual beeps on the PC speaker, each of equal length. The following table
describes the error conditions associated with each beep code and the corresponding POST
checks point code as seen by a ‘port 80h’ card and LCD. For example, if an error occurs at
checkpoint 22h, a beep code of 1-3-1-1 is generated. The “-“ indicates a pause within the
sequence.
Some POST codes occur before the video display is initialized. To assist in determining the
fault, a unique beep-code is derived from these checkpoints as follows:
·
·
·
The 8-bit test point is broken down to four 2-bit groups.
Each group is made one-based (1 through 4)
One to four beeps are generated based on each group’s 2-bit pattern.
Note: Not all POST codes generate a Beep Code.
Example:
Checkpoint 4Bh is divided into:
The beep code is:

6.3 Setup Utility
This section describes the ROM resident Setup utility that provides the means to configure the
platform. The Setup utility is part of the system BIOS and allows limited control over on-board
resources such as parallel port and mouse. The following topics are covered here:
·
·
·
Setup utility operation.
Configuration CMOS RAM definition.
Function of CMOS clear jumper.
6.3.1
Configuration Utilities Overview
On-board devices are configured through the Setup utility that is embedded in flash ROM. Setup
provides enough configuration functionality to boot a system diskette or CD-ROM. Setup is
always provided in flash for basic system configuration.
The configuration utilities modify the CMOS and NVRAM under direction of the user. The actual
hardware configuration is accomplished by the BIOS POST routines and the BIOS Plug-N-Play
Auto-configuration Manager. The configuration utilities always update a checksum for both areas,
so that any potential data corruption is detectable by the BIOS before actual hardware
configuration takes place. If the data is corrupted, the BIOS load the default configuration and
requests that the user reconfigure the system and reboot.
6.3.2
Setup Utility Operation
The ROM-resident Setup utility configures only on-board devices.
The Setup utility screen is divided into four functional areas. Table 31 describes each area:
Table 31. Setup Utility Screen

6.3.2.1
Entering Setup Utility
During POST operation, the user is prompted to enter Setup using the F2 function key as
follows:
Press <F2> to enter Setup
Note that a few seconds might pass before Setup is entered. This is the result of POST
completing test and initialization functions that must be completed before Setup can be entered.
When Setup is entered, the Main Menu options page is displayed.
6.3.2.2
Keyboard Command Bar
The bottom portion of the Setup screen provides a list of commands that are used for navigating
the Setup utility. These commands are displayed at all times, for every menu and submenu.
Each Setup menu page contains a number of features. Except those used for informative
purposes, each feature is associated with a value field. This field contains user-selectable
parameters. Depending on the security option chosen and in effect via password, a menu
feature’s value can be changeable or not. If a value is not changeable due to insufficient security
privileges (or other reasons), the feature’s value field is inaccessible. The Keyboard Command
Bar supports the following:

CMOS Memory Definition
The CMOS map is available in the NVRAM.LST file generated for every BIOS release. The
CMOS map is subject to change without notice.
6.3.4
Clearing CMOS
The BIOS detects the state of the CMOS jumper. If the jumper is set to “CMOS Clear” prior to
power-on or a hard reset, the BIOS changes the CMOS and NVRAM settings to a default state.
This guarantees the system’s ability to boot from floppy.
Password settings are unaffected through CMOS clear. The BIOS clears the ESCD parameter
block and loads a null ESCD image. The boot order information is also cleared when CMOS is
cleared via jumper. The configuration data for the on-board SCSI controllers is not cleared during
a clear CMOS event as each device controls its own default settings
If the Reset Configuration Data option is enabled in Setup, ESCD data and BIOS Boot
specification data is cleared and reinitialized in next boot.
6.4 Flash Update Utility
Note:The Phoenix* PHLASH utility must be run without the presence of a 386 protected mode

uses the processor’s flat addressing mode to update the flash ROM.

The BIOS update utility (PHLASH) loads a new copy of the BIOS into Flash ROM. The loaded

·
·
·
On-board Video BIOS and SCSI BIOS
BIOS Setup Utility
Quiet Boot Logo Area
When running PHLASH in interactive mode, the user may choose to update a particular Flash
area. Updating a flash area takes a file or series of files from a hard or floppy disk, and loads it in
the specified area of Flash ROM.
To manually load a portion of the BIOS, the user must specify which data file(s) to load. The
choices include PLATCBLU.BIN, PLATCXLU.BIN, PLATCXXX.BIN, PLATCXLX.BIN or
PLATCXXU.BIN. The last three letters specify the functions to perform during the flash process:
C = Rewrite BIOS
B = Rewrite Boot block
L = Clear LOGO area
U = Clear user binary
X = place hold

The disk created by the BIOS.EXE program automatically runs “PHLASH /s /b=PLATCXLU.BIN
command” in non-interactive mode. For a complete list of PHLASH options, run “PHLASH /h”.
Once an update of the system BIOS is complete, the user is prompted for a reboot. The user
binary area is also updated during a system BIOS update. User binary can be updated
independently of the system BIOS. CMOS is cleared when the system BIOS is updated.
6.4.2

The BIOS flash ROMincludes a 16 KB area in flash for implementation-specific OEM add-ons.
The user binary area can be saved and updated. The valid extension for user files is *.ROM.

The system BIOS language area can be updated only by updating the entire BIOS. The BIOS
supports English, Spanish, French, German, and Italian. These languages are selectable using
Setup.
6.4.4
OEM Logo Screen
A 128 KB region of Flash ROMis available to store the OEM logo in compressed format. The
BIOS contains the standard Intel logo. Using the Phoenix* PHLASH utility, this region can be
updated with an OEM supplied logo image. The OEM logo must fit within 640 X 384 size. If an
OEM logo is flashed into the system, it overrides the built in Intel logo.
6.4.5
Recovery Mode
The SDS2 baseboard supports a method for performing a BIOS recovery in order to restore the
system from a failed flash. This utilizes a jumper on the baseboard. The system beeps through
out the process. The recovery BIOS boots only from a 1.44 MB floppy diskette inserted into a
1.44 MB floppy drive or LS-120/240 drive. Nothing is displayed to the video screen during the
recovery process.
Note:The user must make the Recovery floppy diskette following the instructions included in the
release notes. Failure to do so will cause the process to fail.
6.4.5.1
Performing BIOS Recovery
The follow procedure boots the recovery BIOS and flashes the normal BIOS.
1. Prepare a BIOS recovery diskette by following the instructions included with the BIOS
release.
2. Turn off system power.
3. Move the BIOS recovery jumper to the recovery position.
4. Insert the BIOS recovery diskette.

5. Turn on system power.
The system boots from the recovery diskette. The BIOS will beep twice when the update
process starts. The system will continue to beep while updating the BIOS. If BIOS update
completes successfully, the system will stop beeping. If the update fails, the system will sound
an alternating pattern of a buzz and a beep.
When the flash update completes:
1. Turn off system power.
2. Remove the recovery diskette.
3. Restore the recovery jumper to its original position.
4. Turn on system power.
5. Flash any custom blocks such as user binary.
The system should now boot normally using the updated system BIOS.

Fixed. This issue is fixed in SDS2 BIOS Production Release 2.5 (Build 48) and
later versions.
15. SDS2 Build Your Own (BYO) Platform Confidence Test (PCT)
v. 1.00 fails on the first run
Problem:
The first time the SDS2 BYO PCT v. 1.00 is run on an SDS2 system following a
cold boot, the following error message will be encountered:
***ERROR BMC.CHECKCHASSISSTATUS V4.11.1.0107
Chassis Status miscompared with known values.
EXP: 210101h, RCVD: 210001h, MASK: FFFFFFFFh
Standard Error Code = 0BE1501F
BMC.CHECKCHASSISSTATUS FAILED
This issue is not seen if the SDS2 BYO PCT v. 1.00 is re-run a second time
without restarting the system, or after restarting the system with a Ctrl-Alt-Del
warm boot.
Implication:
The SDS2 PCT v. 1.00 will fail with the BMC Check Chassis Status test when
the test is run following a cold boot.
Workaround:
Status:
None.
Fixed. This issue is due to the SDS2 BYO PCT v. 1.00 incorrectly identifying an
error condition. This issue has been fixed in SDS2 BYO PCT v. 1.01. SDS2
BYO PCT v. 1.01 will be added to the SDS2 system resource CD-ROM in
future engineering change order (ECO).

In addition to this message, the SC5100 front panel system status LED will light
solid amber, indicating a system temperature fault.
This condition will continue to appear during POST each time the SDS2 system
is rebooted, until AC power is removed from the system by disconnecting the
AC power cord.
Implication:
The described condition will appear if the SC5100 front panel cable is
disconnected from the SDS2 server board and then reconnected while 5V
standby voltage is applied to the system.
Workaround:
Status:
Disconnecting the AC power cord from the system will clear this condition.
NoFix. Disconnecting and reconnecting the SC5100 front panel cable from the
SDS2 server board while 5V standby voltage is applied to the system is not a
supported action. This action causes the SC5100 front panel temperature
sensor to report an invalid temperature reading. Customers must disconnect
the AC power cord from the SDS2/SC5100 system before disconnecting or
reconnecting the SC5100 front panel cable to the server board.
17. SDS2 0B75: System Voltage out of the range POST message
Problem:
The following message may be encountered during POST when SDS2
FRU/SDR files v. 5.0.B and previous versions are programmed on the SDS2
server board:
System Monitoring Check
0B75: System Voltage out of the range
(Press <F1> to override boot suppression, or <F2> to enter Setup)
This issue
Implication:
The described condition may appear if SDS2 FRU/SDR files v. 5.0.B or
previous versions are programmed on the SDS2 server board.
Workaround:
Status:
Disconnecting the AC power cord from the system will clear this condition.
Fixed. SDS2 FRU/SDR files v. 5.0.B and previous versions contain slightly
incorrect SDR values for the Vbat voltage (battery backup voltage). The Vbat
voltage sensor values have been corrected in SDS2 FRU/SDR files v. 5.0.D
and later versions.
18. Miscellaneous numeric keys entered during POST enable PXE
boot
Problem:
Entering various numeric key sequences during POST will cause the SDS2
system BIOS to enter the PXE boot sequence. The BIOS should only enter the
PXE boot sequence when the F12 key is pressed during POST.

19. SDS2 board level operating temperature and power supply
voltage tolerance modification
Problem:
In Table 73 of the Intel® Server Board SDS2 Technical Product Specification
(TPS) Rev. 1.0, the board level operating temperature is specified as 0°C to
55°C. In Table 75 of the SDS2 TPS Rev. 1.0, the power supply tolerance is
specified as ±5% for the 3.3V rail. Intel has induced a failure condition during
board level temperature and voltage margin testing at 55°C and ±5% voltage on
the 3.3V rail in SDS2 Server Boards configured with PCI adapters in the
64bit/66MHz PCI slots under extreme workloads during final validation testing.
As a result, the SDS2 Server Board board level operating temperature
specification has been modified to 0°C to 45°C, and the power supply tolerance
specification for the 3.3V rail has been modified to ±3%. The SDS2 Server
Board passes board level temperature and voltage margin testing performed
according to these modified specifications.
Implication:
The SDS2 Server Board’s operating environment should be maintained within
the modified board level operating temperature specification of 0°C to 45°C and
the modified power supply tolerance specification of ±3% for the 3.3V rail. The
power supply tolerance specification for the 5V, 12V, and 5V standby rails is still
±5%. The system level operating temperature specification of the Intel® Server
Board SDS2 integrated into the Intel® SC5100 Server Chassis is still 0°C to
35°C. The Intel SC5100 Server Chassis’ cooling system is capable of
maintaining a SDS2 board level temperature below 45°C at a 35°C system
ambient temperature.
Workaround:
Status:
None.
Fix. Intel has identified a fix for this issue, which will be incorporated in the
SDS2 FAB 5 server board.
20. Recommendation for SDS2 rubber bumper installation
Problem:
A rubber bumper is included with the Intel® Server Board SDS2. Intel
recommends installing this bumper on the chassis before integrating the board
into the chassis, in order to improve the board’s tolerance to vibration that may
occur during shipment of the integrated system product.

Implication:
If you are installing the Intel Server Board SDS2 into the Intel SC5100 Server
Chassis, Intel recommends installing the rubber bumper included with the
server board. If you are installing the Intel Server Board SDS2 into a chassis
other than the Intel SC5100 Server Chassis, compare the rubber bumper height
to the chassi standoff height. If the bumper is the same height as the standoffs
in the chasis, install the rubber bumper included with the SDS2 Server Board. If
the suport is not the same height, procure a bumper that matches the height of
the standoffs used in your chassis. The rubber bumper should be installed on
the chassis as follows:
For the Intel SC5100 chassis:
1.Remove the backing from one of the rubber bumpers included with your
chassis.
2.Press the rubber bumper firmly into place approximately ½ inch (2 cm) to the
right of the chassis baseboard hole marked “9.” See location Abelow.
For other chassis:
1.Remove the backing from one of the rubber bumpers included with your
chassis.
2.Locate the chassis standoff labeled “1” in your chassis.
3.Place the rubber bumper at a location 6.25 inches (16 cm) toward the front of
the chassis and 7.75 inches (19 cm) toward the center of the chassis from
standoff 1. See location B below.
4.Press the rubber firmly into place.

23. Boot to service partition via modem fails
Problem:
When utilizing the direct platform control (DPC) feature of Intel Server Control
(ISC) v. 3.5.2 software to boot a SDS2 server board to the service partition via
modem, the server board will hang during ROM-DOS load.
Implication:
The DPC feature of ISC v. 3.5.2 software cannot be used to remotely boot the

26. Bootable CD will not boot if inserted during OPTION ROM scan
Problem:
During POST while the OPTION ROM scan for the on board (OB) devices and
add in PCI adapters is in process, if an bootable CD-ROM is inserted in to he
CD-ROM, the system will not attempt to boot to the CD-ROM. An attempt to
boot to the floppy was made and then the OS on the hard drive booted. No
attempt was made to boot to the bootable CDROM.
Implication:
Bootable CD-ROM must be inserted before POST begins or the system is
reset.
Workaround:
Status:

Will not fix.
27. Swapping bootable for non-bootable CDROM during POST
causes hang at boot.
Problem:
Powered on the system with a bootable Win2k AS CD in the CDROM drive. As
soon as the BIOS began to POST add-in cards with OPTION ROMS the
Bootable CD was ejected and a non-bootable CD was inserted. When the
system completed POST and attempted to boot, the floppy drive showed an
access attempt. The system then hanged with a blinking cursor on a black
background. The boot order was set with 1)Floppy 2) CDROM 3) Hard Drive.
Workaround:
Status:
Reset the system. BIOS does not rescan status of boot devices upon
completion of POST.

28. OB P100 NICs do not show at POST but attempt PXE boot and
appear in Boot Menu
Problem:
On board NIC are not displayed during post but do appear in Boot Device menu.
These controllers will also attempt to do a PXE boot if no other bootable devices
are found.
Implication:
Not all boot devices displayed during POST when diagnostic display is enabled.
Workaround:
None. This is by design. The system BIOS builds the on-board network
controller Option ROM with an option that always makes the OPROM “quiet”. It
therefore does not display any text messages and does not allowing the CTRL-
S option.
Status:
Will not fix.
29. Dodson: Adaptec 39160 in slots 5 & 6 causes Expansion ROM
error
Problem:
Add in Adaptec 39160 Ultra 160 controller installed in slots 5 & 6 causes an
Expansion ROM error after last system POST. No other adapters are present.
Implication:
Workaround:
Error message: Expansion ROM not initialized - PCI Mass Storage controller in
slot 06. Bus: 02, Device: 09, Function: 01
Adaptec's single image Option ROM requires one 'master' controlling channel
that is set using the <Ctrl-A> SCSI Select utility. Each channel loads the Option
ROM, determines whether it is the 'master' channel, and if not it unloads
completely. If it is the 'master', it proceeds to scan all devices and list all
possible drives. Only one channel does this scanning, but ALL channels load
the Option ROM initially if the Option ROM is enabled on the slot.
The error is coming from the second channel on the Adaptec 39160, even
though the first channel has already completed the 'master' scan. The reason it
is only happening in Slots 5 and 6 and when the NIC Option ROMs are all
loaded is because that is when the available Option ROM space is at a
minimum. The NIC Option ROM's are small, but apparently they make enough
difference. The onboard 7899 Option ROM loads after Slots 1-4, but before
Slots 5 & 6.
The solution here is to enable channel B of the ASC39160 as the 'master'
channel. When this is done, channel A loads the Option ROM, sees that it is not
the 'master', and unloads. Then channel B loads the Option ROM, does the full
scan of all devices, and remains in memory. At this point no other channels are
found, so no other devices error. The key here is that the LAST available
Adaptec channel should be listed as the Master - unfortunately, this is opposite
from their default - they default to the first available channel.

33. 3COM* 3C980C-TX NIC causes Microsoft* Windows* 2000 blue
screen when greater than 4GB of system memory is installed
Problem:
Intel has induced blue screens under Microsoft* Windows* 2000 in SDS2
sytems configured with a 3COM* 3C980C-TX NIC with driver el98xn5.sys
v3.48.0.0, and greater than 4GB of system memory installed, under extreme
workloads during network validation testing. This issue is not seen when up to
4GB of system memory is installed in the SDS2 system.
Implication:
Blue screens may be encountered under Microsoft* Windows* 2000 when
using a 3COM* 3C980C-TX NIC in an SDS2 system with greater than 4GB of
system memory installed.
Workaround:
This issue results because the 3COM 3C980C-TX NIC does not physically
support dual address cycles (DAC), therefore, the NIC is not able to access
physical addresses above 4GB. Due to negative performance impact, Intel
does not recommend using a NIC adapter that does not support DAC or 64-bit
PCI on a system with greater than 4GB of system memory installed. Intel
recommends installing a maximum of 4GB of system memory in the SDS2
system when utilizing the 3COM* 3C980C-TX NIC.
This issue does not occur when 3COM driver el98xn5.sys v4.0.0.15, which is
available on the Microsoft* Windows.NET* CDROM, is used, instead of 3COM
driver el98xn5.sys v3.48.0.0. This is another possible workaround for this
issue.
