Motherboard Description  
1.5 Microprocessor  
The AP440FX motherboard operates with 2.1 V to 3.5 V Pentium Pro processors. An onboard  
voltage regulator circuit provides the required voltages from the 5 V and 3.3 V taps off the power  
supply. The onboard voltage regulator makes use of the VID capabilities to automatically adjust  
its voltage output to match that of the installed processor. Pentium Pro processors running at 150,  
166, 180, and 200 MHz are supported.  
The Pentium Pro processor integrates the second level cache and cache controller that were  
previously implemented on the motherboard. The internal, non-blocking L2 cache on the 150, 180  
and 200 MHz processors is 256 KB, while second versions of the 166 and 200 MHz processors  
integrate a 512 KB cache. The Pentium Pro processor has an advanced numeric coprocessor that  
significantly increases the speed of floating point operations, while maintaining backward  
compatibility with math coprocessors that comply with ANSI/IEEE standard 754-1985.  
NOTE  
If you are installing a 3.5 V processor, a jumper must be installed on the jumper block located at  
J8A2. See Section 1.13 for more information.  
NOTE  
The 200 MHz Pentium Pro processor with 512 KB of cache memory is not supported on the  
AP440FX motherboard.  
1.5.1 Microprocessor Upgrade  
Socket 8 is a 387-pin, modified staggered pin grid array (SPGA) zero insertion force (ZIF) socket,  
along with a programmable voltage regulator for the microprocessor core. It provides users with a  
performance upgrade path to OverDrive processors. The voltage regulator programming is  
automatic and controlled by the VID pins of the processor.  
1.5.2 Microprocessor Heatsink and Clips  
An approved Pentium Pro processor heatsink is necessary for proper thermal dissipation in an LPX  
compliant chassis. The processor/heatsink assembly must be securely fastened to the Socket 8 ZIF  
socket by two clips. These clips fit over the heatsink assembly and attach to the outer wide tabs of  
the Socket 8 assembly.  
CAUTION  
Do not use the older style of bail-wire clips for securing the heatsink assembly. These clips have  
been found to damage the motherboard when installed or removed incorrectly.

AP440FX Motherboard Technical Product Specification  
1.6 Main System Memory  
The motherboard has four 72-pin tin-lead SIMM sockets that make it possible to install up to  
128 MB of RAM. The sockets support 1M x 32 (4 MB) single-sided modules, 2M x 32 (8 MB),  
4M x 32 (16 MB), and 8M x 32 (32 MB) single- or double-sided modules. Minimum memory size  
is 8 MB and maximum memory size, using four 8M x 32 SIMM modules, is 128 MB. Memory  
timing requires 60 ns fast page devices or, for optimum performance, 60 ns EDO DRAM. Both  
parity and non-parity memory modules are supported. With parity SIMMs, the board can be  
configured to support ECC operation.  
The four sockets are arranged in two banks of two sockets each. The sockets are designated  
Bank 0 and Bank 1. Each bank provides a 64/72-bit wide data path. Both SIMMs in a bank must  
be of the same memory size and type, although the types and sizes of memory may differ between  
banks. Bank 0 only, Bank 1 only, or both of the banks may be populated. There are no jumper  
settings required for the memory size or type, which is automatically detected by the BIOS. Use  
only tin lead SIMMs when adding DRAM.  
1.6.1 DRAM  
EDO (or Hyper Page) DRAM is designed to improve the DRAM read performance. EDO DRAM  
holds the memory data valid until the next memory access cycle, unlike standard fast page mode  
DRAM that tri-states the memory data when the precharge cycle occurs, prior to the next memory  
access cycle.  
1.6.2 Parity and ECC DRAM  
Memory error checking and correction is supported by parity SIMMs. With parity SIMMs, the  
board can be configured to support ECC memory operation. Parity SIMMs are automatically  
detected, but the user must enter Setup to configure the SIMMs for either Parity or ECC operation.  
Parity memory detects single bit errors. ECC memory detects double bit errors and corrects single  
bit errors. Errors may be generated by a defective memory module, by different speeds of memory  
modules, or by DMA or memory conflicts.  
1.7 Chipset  
The Intel 82440FX PCIset consists of the 82441FX PCI Bridge and Memory controller (PMC) and  
the 82442FX Data Bus Accelerator (DBX). The Intel 82371SB PCI ISA/IDE Xccelerator (PIIX3)  
bridge, provides the connection between the ISA and PCI buses.  
1.7.1 82441FX PCI Bridge and Memory Controller (PMC)  
The 82441FX comes in a 208 pin QFP package and provides the following features:  
Microprocessor interface control  
Pentium Pro processor host bus up to 66 MHz  
32-bit addressing

and the 16 bit PMC private data bus. The DBX works in parallel with the PMC to provide a high  
performance memory subsystem for Pentium Pro processor based computers. The DBX comes in  
a 208 pin PQF package.  
1.7.3 82371SB PCI/ISA IDE Xccelerator (PIIX3)

AP440FX Motherboard Technical Product Specification  
1.7.4 IDE Support  
The motherboard provides two independent high performance bus-mastering PCI IDE interfaces  
capable of supporting PIO Mode 3 and Mode 4 devices. The BIOS supports Logical Block  
Addressing (LBA) and Extended Cylinder Sector Head (ECHS) translation modes as well as ATAPI  
(e.g., CD-ROM) devices on both IDE interfaces. Detection of IDE device transfer rate and  
translation mode capability is automatically determined by the BIOS.  
Normally, programmed I/O operations require a substantial amount of microprocessor bandwidth.  
In true multi-tasking operating systems like Windows95, the microprocessor bandwidth freed up  
by using PCI bus mastering IDE can be used to complete other tasks while disk transfers are  
occurring. When used in conjunction with the appropriate driver for the Windows 95 environment,  
the IDE interface can operate as a PCI bus master capable of supporting PIO Mode 4 devices with  
transfer rates of up to 16 MB/sec.  
Detailed information on the PCIset is available in the Intel 82440FX PCISet data sheet.  
1.7.5 Secure Flash Support  
The AP440FX motherboard uses both onboard hardware and BIOS code support to protect the  
onboard flash memory device from accidentally or intentionally being corrupted. A general  
purpose I/O (GPIO) port of the I/O controller is used to control the write enable line of the flash  
device. By putting the microprocessor in System Management Mode (SMM) whenever the flash  
write is enabled, the BIOS can ensure that the SMM code is not corrupted and that flash can only  
be written from within SMM.  
1.7.6 USB Support  
The AP440FX motherboard has two USB ports. This permits connection of two USB peripheral  
devices directly to the computer without an external hub. If more devices are required, an external  
hub can be connected to either of the built-in ports. The motherboard completely supports the  
standard universal host controller interface (UHCI) and takes advantage of the standard software

Motherboard Description  
1.8 PC87307 Super I/O Controller  
Control for the integrated serial ports, parallel port, floppy drive, real-time clock, and keyboard  
controller is incorporated into a single component, the National Semiconductor PC87307. The  
PC87307 is a fully Plug and Play compatible device which provides:  
Two NS16C550-compatible UARTs with send/receive 16 byte FIFO  
Support for an IrDA and Consumer IR compliant Infrared interface  
Multi-mode bi-directional parallel port  
Standard mode; IBMand Centronicscompatible  
Enhanced Parallel Port (EPP) with BIOS/Driver support  
High Speed mode; Extended Capabilities Port (ECP) compatible  
Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)  
Integrated Real Time Clock with Century calendar functionality  
Integrated 8042 compatible keyboard controller  
The PC87307 is normally configured automatically by the BIOS, but configuration of these  
interfaces also is possible using the CMOS Setup utility that can be invoked during boot. The  
serial ports can be enabled as COM1, COM2, COM2 as IrDA, or disabled. The parallel port can  
be configured as compatible, bi-directional, EPP/ECP, or disabled. The floppy interface can be  
configured for 360 KB or 1.2 MB 5¼" media or for 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB  
3½" media.  
1.8.1 Floppy Controller  
The PC87307 is software compatible with the DP8473 and 82077 floppy disk controllers. The  
floppy interface can be configured for 360 KB or 1.2 MB 5¼" media or for 720 KB, 1.2 MB,  
1.44 MB, or 2.88 MB 3½" media in the BIOS setup. By default, the Floppy A interface is  
configured for 1.44 MB and Floppy B is disabled. Configuring the floppy interface for 1.2 MB  
3½" (3-mode floppy) requires the use of a driver to operate correctly.  
1.8.2 Keyboard and Mouse Interface  
PS/2 keyboard/mouse connectors are located on the back panel side of the motherboard. The 5V  
lines to these connectors are protected with a PolySwitchcircuit which acts much like a self-  
healing fuse, re-establishing the connection after an over-current condition is removed. While this  
device eliminates the possibility of having to replace a fuse, care should be taken to turn off the  
power before installing or removing a keyboard or mouse.  
The integrated 8042 microcontroller contains the AMI Megakey keyboard/mouse controller code  
which, besides providing traditional keyboard and mouse control functions, supports Power-  
On/Reset (POR) password protection. The POR password can be defined by the user in the Setup  
program. The keyboard controller also provides for the following “hot-key” sequences:  
<CTRL> <ALT> <DEL>: System software reset. This sequence performs a software reset of  
the computer by jumping to the beginning of the BIOS code and running the POST operation.

AP440FX Motherboard Technical Product Specification  
<CTRL> <ALT> <defined in Setup>: Power down and coffee-break key sequences take  
advantage of the SMM features of the Pentium Pro processor to greatly reduce the computer’s  
power consumption while maintaining the responsiveness necessary to service external  
interrupts.  
<CTRL> <ALT> <defined in Setup>: Keyboard secure hot keys lock the keyboard until user  
specified password is given.  
1.8.3 Real-Time Clock, CMOS RAM and Battery  
The integrated real-time clock is compatible with DS1287 and MC146818 components. It  
provides a time of day clock, a 100-year calendar with alarm features, and a century register. The  
real-time clock can be set in the Setup program. The real-time clock also supports 242-byte  
battery-backed CMOS RAM in two banks which is reserved for BIOS use. The CMOS RAM can  
be set to specific values or cleared to the default values using the Setup program. Also, the CMOS  
RAM values can be cleared to the defaults by using a configuration jumper on the motherboard.  
An external coin-cell style battery provides power to the real-time clock and CMOS memory. The  
battery used is a long-life version that is socketed for easy replacement. When the computer is on,  
the life of the battery is extended by a trickle current from the power supply.  
1.8.4 Infrared Support  
A 5-pin interface on the front panel I/O connector allows connection to a Hewlett PackardHSDL-  
1000 compatible infrared (IrDA) transmitter/receiver. Once the module is connected to the front  
panel I/O header, Serial port 2 can be redirected to the IrDA module. When configured for IrDA,  
the user can transfer files to or from portable devices such as laptops, PDAs and printers using  
application software such as LapLink. The IrDA specification provides for data transfers at  
115kbps from a distance of 1 meter. Support for Consumer Infrared (ASK-IR and DASK-IR  
options for SHARP-IR) is also included. Consumer infrared is supported at both slow and medium  
speeds.  
1.8.5 Parallel Port  
A 25-pin D-Sub header is provided on the back panel for a multi-mode bi-directional parallel port.  
The parallel port operates in standard mode, Enhanced Parallel Port (EPP) version 1.7 mode, with  
BIOS and Driver support, and a high speed Extended Capabilities Port (ECP) compatible mode.  
EPP Mode requires a driver provided by the peripheral manufacturer to operate correctly.  
1.9 Graphics Subsystem  
The AP440FX motherboard is available with a factory option of an S3 ViRGEor ViRGE/DX  
SVGA graphics controller. Both options are supported by 2 MB of 50 ns EDO SOJ DRAM  
soldered to the motherboard. The AP440FX motherboard also supports the S3 media channel, also  
known as the Local Peripheral Bus (LBP) or Scenic Highway.

Motherboard Description  
1.9.1 S3 ViRGE Graphics Subsystem  
The AP440FX motherboard is available with a factory option of an S3 ViRGE SVGA graphics  
controller with 2 MB of 50 ns EDO SOJ DRAM. The S3 ViRGE has a high performance 64-bit  
2D/3D graphics engine and incorporates the S3 Streams Processor that enables the device to  
convert YUV formatted video data to RGB and provides acceleration for scaling the video display  
without compromising picture quality or frame rate. The on-chip RAMDAC/clock synthesizer is  
capable of output pixel data rates of 135 MHz providing non-interlaced screen resolutions of up to  
1280x1024x256 colors at 75 Hz. The 64-bit S3d Engine incorporates the key Windows and other  
GUI accelerator functions of BitBLT, line draw and polygon fill. 3D features include flat shading,  
Gouraud shading and texture mapping support. Advanced texture mapping features include  
perspective correction, bi-linear and tri-linear filtering, MIP-mapping, and Z-buffering. These  
features provide the most realistic user experience for interactive 3D applications. In addition, a  
fast linear addressing scheme based upon DCI reduces software overhead by mapping the display  
memory into the microprocessor’s upper memory address space and permitting direct  
microprocessor access to the display memory.

Motherboard Description  
1.12.1.1 SW_ON  
This 2-pin header connects to a front panel power switch. When the switch is closed, the power  
supply turns on. If a mechanical switch is connected to this header, it must apply a momentary  
ground to the SW_ON header pin in order to signal the supply to turn on or off. Because of the  
motherboard’s internal debounce circuitry, the ground must be applied for at least 50ms. At least  
two seconds must pass before the power supply will recognize another on/off signal (to prevent  
“double clicking”).  
1.12.1.2 Sleep/Resume  
When Advanced Power Management (APM) is activated in the BIOS and the Operating System’s  
APM driver is loaded, Sleep mode (Standby) can be entered in one of three ways:  
An optional front panel “Sleep/Resume” button  
A user defined keyboard hot key  
Prolonged computer inactivity  
The Sleep/Resume button is supported by a 2-pin header located on the front panel I/O connector.  
Closing the “Sleep” switch generates an SMI (System Management Interrupt) to the processor  
which immediately goes into System Management Mode (SMM).  
The front panel “Sleep mode” switch must be a momentary two pin SPST type that is normally  
open. The function of the Sleep/Resume button can also be achieved by using a keyboard hot-key  
sequence, or by a time-out of the inactivity timer. Both the keyboard hot key and the inactivity  
timer are programmable in the BIOS Setup (timer is set to 10 minutes by default). To reactivate  
the computer, or “Resume”, the user must simply press the sleep/resume button again, or use the  
keyboard or PS/2 mouse. Mouse activity only “wakes up” the computer if a mouse driver is  
loaded. While the computer is in Standby or “sleep” mode, it is fully capable of responding to and  
servicing external interrupts (such as in-coming FAX) even though the monitor only turns on if a  
user interrupt (keyboard/mouse) occurs as mentioned above.  
1.12.1.3 Infrared Connector  
Serial port 2 can be configured to support an IrDA module with a 5 pin header connector. Once  
configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDAs  
and printers using application software such as LapLink. The IrDA specification provides for data  
transfers at 115 Kbps from a distance of 1 meter. Consumer IR is also supported by the same  
connector.  
1.12.1.4 Hard Drive LED  
This 3-pin, keyed header can be connected to a front panel LED to indicate when hard drive  
activity is taking place. When the hard drive is being accessed, the HDACTIVE pin (J2A1-15)  
goes low.  
1.12.1.5 Power-ON LED  
This 2-pin header can be connected to a front panel LED to indicate when power is applied to the  
motherboard. When the motherboard is powered up, power is applied to the PWRDRV pin  
(J2A1-20) to light the front panel LED.

AP440FX Motherboard Technical Product Specification  
1.12.1.6 Reset  
This 2-pin header can be connected to a momentary SPST type switch that is normally open.  
When the switch is closed, the computer performs a hard reset and runs POST.  
1.12.1.7 Speaker  
The speaker provides error beep code information during the POST, if the computer cannot use the  
video interface. Jumpering pins 26-27 (the last two pins of J2A1) engage the onboard speaker. To  
disable the onboard speaker (and allow use of the chassis speaker), remove the jumper from these  
pins.

Motherboard Description  
1.12.2 Memory/Expansion Connectors  
The AP440FX motherboard has four 72-pin SIMM sockets for main memory. These sockets  
accept standard SIMM 72-pin modules, as long as they satisfy the requirements described in the  
“Main System Memory” section of this specification, starting on page 12.  
The AP440FX motherboard uses a PCI/ISA riser connector (J6J2) to provide for expansion PCI or  
ISA boards. The associated riser board can support either two or three PCI slots. A pair of  
jumpers on the AP440FX motherboard must be set to define the number of PCI slots on the riser  
board. Refer to Figure 8 on page 35 for jumper block details. Table 7 shows the pinout listing for  
the PCI/ISA riser connector.

Motherboard Description  
1.12.6 Power Supply Connectors  
The AP440FX motherboard must be used with a power supply that supports remote power on/off,  
so the motherboard can turn off the power under software control. The Powerman utility supplied  
for Windows 3.1x allows for soft-off as does the shutdown icon in Windows 95 Start menu. The  
BIOS turns the power off when it receives the proper APM command from the operating system.  
For example, Windows 95 issues this APM command after the user selects “Shutdown the  
computer” option. APM must be enabled in the BIOS and operating system in order for the soft-  
off feature to work correctly. The user has the ability to determine the state of the power supply, so  
if the computer was turned on when power was disconnected, the computer turns back on when  
power is reapplied or it remains off, depending on the user setup configuration in CMOS.  
Table 13 provides the pinout listing for the primary power supply connector of the AP440FX  
motherboard.

Motherboard Description  
1.13 Jumper Settings  
There are three jumper blocks on the AP440FX motherboard. The jumper block at J1J1 defines the  
number of PCI slots (two or three slots) available on the riser board used with the motherboard.  
The jumper block at J4L2 defines a range of microprocessor and motherboard configuration  
parameters. The jumper block at J8A2 is used to provide 3.5 V for processors that require that  
voltage. Figure 8 shows the jumper block locations on the motherboard, and indicates how jumper  
placement corresponds to the value defined by the motherboard silk-screening.

The jumpers for sections D, E, F, G, and H of J4L2 allow the selection of various motherboard  
features. A second jumper block (J1J1) allows selection of a riser board with either two or three  
PCI board connectors. A third jumper (J8A2) is used to provide 3.5 V for processors that require  
that voltage.  
CAUTION  
Do not install a jumper on the J8A2 header if you are using a processor that does not require  
3.5V. The increased voltage could damage the processor.

2.3 Soft-Off Control  
The motherboard design uses Soft-off control implemented under the SMM code in the BIOS.  
Any power supply used with the AP440FX motherboard must support the Soft-off feature. The  
ONCTL# pin of the I/O controller is connected to the Soft-off control line in the power supply  
circuit. The registers in the I/O controller that set the I/O address and control the ONCTL# pin are  
not setup until the SMM code is activated.

3 Motherboard BIOS and Setup Utility  
3.1 Introduction  
The AP440FX motherboard uses an Intel BIOS, which is stored in flash memory and easily  
upgraded using a floppy disk-based program. In addition to the Intel BIOS, the flash memory also  
contains the Setup utility, Power-On Self Tests (POST), APM 1.2, the PCI auto-configuration  
utility, and Windows 95 ready Plug and Play 1.0a. This motherboard also supports BIOS  
shadowing, allowing the BIOS to execute from 64-bit onboard write-protected DRAM.  
The BIOS displays a sign-on message during POST identifying the type of BIOS and a five-digit  
revision code. The initial production BIOS in the motherboard is identified as 1.00.01.CT1.  
3.2 BIOS Flash Memory Organization  
The Intel PA28FB002BX 2 MB flash component is organized as 256K x 8 (256 KB). The flash  
device is divided into seven areas, as described in Table 33.

3.3 BIOS Upgrades  
Flash memory makes distributing BIOS upgrades easy. A new version of the BIOS can be  
installed from a diskette. BIOS upgrades are available to be down loaded from the Intel  
Applications Support web site at http://www-cs.intel.com/oem_developer/motherbd/, or from  
Intel’s FTP site at ftp://ftp.intel.com/pub/bios/. Be sure to have the BIOS identification that applies  
to this motherboard.

Download from Www.Somanuals.com. All Manuals Search And Download.  
AP440FX Motherboard Technical Product Specification  
The disk-based Flash upgrade utility, FMUP.EXE, has three options for BIOS upgrades:  
The Flash BIOS can be updated from a file on a disk.  
The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the  
event that an upgrade cannot be successfully completed.  
The BIOS in the Flash device can be compared with a file to ensure the computer has the  
correct version.  
The upgrade utility ensures the upgrade BIOS extension matches the target computer to prevent  
accidentally installing a BIOS for a different type of computer.  
3.4 PCI IDE Support  
The two local bus IDE connectors with independent I/O channel support are setup up automatically  
by the BIOS if the user selects “Autoconfiguration” in Setup. The IDE interface supports PIO  
Mode 3, and Mode 4 hard drives and recognition of ATAPI CD-ROMs, tape drives, and any other  
ATAPI devices. The BIOS determines the capabilities of each drive and configures them to  
optimize capacity and performance. For the high capacity hard drives typically available, the drive  
is automatically configured for Logical Block Addressing (LBA) for maximum capacity and to  
PIO Mode 3 or 4 depending on the capability of the drive. The user can override the auto-  
configuration options by using the manual mode setting. The ATAPI Specification Revision 2.5  
recommends that an ATAPI device be configured as shown in Table 34.

3.5 PCI Auto-Configuration  
The PCI auto-configuration utility operates in conjunction with the Setup utility to allow the  
insertion and removal of PCI cards without user intervention (Plug and Play). When the computer  
is turned on after adding a PCI add-in card, the BIOS automatically configures interrupts, I/O  
space, and other parameters. PCI interrupts are distributed to available ISA interrupts that have not  
been assigned to an ISA card, or other resources. Those interrupts left set to “available” in Setup  
are considered free for PCI add-in card use.  
The PCI Auto-Configuration function complies with version 2.10 of the PCI BIOS specification.  
Configuration information is stored in ESCD format. The ESCD data may be cleared (i.e., “write  
protection” is removed) by setting the CMOS clear jumper to the DOWN (CLR) position.  
46

Motherboard BIOS and Setup Utility  
PCI specification 2.1 for add-in card auto-configuration is also a part of the Plug and Play BIOS.  
Peer-to-peer hierarchical PCI Bridge 1.0 is supported, and by using an OEM supplied option ROM  
or TSR, a PCI-to-PCMCIA bridge capability is possible as well.  
3.6 ISA Plug and Play  
The BIOS incorporates ISA Plug and Play capabilities as delivered by Plug and Play Release 1.0A  
(Plug and Play BIOS V.. 1.0A, ESCD V.. 1.03). When used in conjunction with the ISA  
Configuration Utility (ICU) for DOS or Windows 3.x, the computer allows auto-configuration of  
Plug and Play ISA cards, PCI cards, and resource management for legacy ISA cards. Because the  
BIOS supports configuring devices across PCI bridges, release 1.41 or greater of the ICU must be  
used with the motherboard to properly view and change settings. Configuration information is  
stored in ESCD format. The ESCD data may be cleared (i.e., “write protection” is removed) by  
setting the CMOS clear jumper to the DOWN (CLR) position.  
The BIOS also has a setup option to support the Windows 95 run time Plug and Play utilities.  
When this option is selected, only devices critical to booting are assigned resources by the BIOS.  
Device Node information is available for all devices to ensure compatibility with Windows 95.  
Copies of the Intel Architecture Laboratory (IAL) Plug and Play specification may be obtained  
from the Intel World Wide Web site at http://www.intel.com/IAL/plugplay/.  
3.7 Desktop Management Interface (DMI)  
DMI is a method of managing computers in an enterprise. The main component of DMI is the  
Management Information Format Database (MIF), which contains information about the computer  
and its components. Using DMI, a system administrator can obtain the types, capabilities,  
operational status, installation date and other information about the computer’s components. The  
DMI specification requires that certain information about the motherboard be made available to an  
applications program. This user-defined information is located in a series of data structures which  
are accessed in various ways by means of the DMI service layer. Component instrumentation  
allows the service layer to gain access to the information stored in the GPNV. The included MIF  
database defines the data and provides the method for accessing the information.  
The AP440FX BIOS provides the first stage of DMI v. 2.0 support, including static system  
configuration information, including motherboard and peripheral data. Future AP440FX product  
releases will provide event detection and error logging, achieving the maximum benefit of DMI  
with applications such as LANDesk Client Manager from Intel.

AP440FX Motherboard Technical Product Specification  
3.8 Advanced Power Management (APM)  
This section describes the use of System Management Mode (SMM) by the BIOS. The BIOS  
supports APM version 1.2. APM is enabled in BIOS by default; however, the computer must be  
configured with an APM driver to utilize the system power saving features. Windows 95 enables  
APM automatically upon detecting the presence of the APM BIOS.  
The energy saving Standby mode can be initiated by one of the following:  
a keyboard hot-key sequence set by the user  
a time-out period set by the user  
a suspend/resume button tied to the front panel sleep connector.  
When in Standby mode, the motherboard reduces power consumption by utilizing the Pentium Pro  
processor’s SMM capabilities and also spinning down hard drives and turning off VESA DPMS  
compliant monitors. The user may select which DPMS mode (Standby, Suspend, or Off) to send  
to the monitor in Setup. The ability to respond to external interrupts is fully maintained while in  
Standby mode allowing the system to service requests such as an in-coming fax or network  
message while unattended. Any keyboard or mouse activity brings the system out of the energy  
saving Standby mode. When this occurs the monitor and IDE drives are turned back on  
immediately.  
Because SMM uses its own address space, the pointers to interrupt service routines in protected  
mode do not necessarily point to the executable interrupt service routines when the processor goes  
into SMM. Interrupts are disabled upon entry into SMM. Any program that wants to use  
interrupts during SMM must provide a valid interrupt service routine and place a pointer to it in an  
interrupt descriptor table before renabling interrupts.  
Windows 95 places an Energy Star compliant monitor in video standby mode after a period of  
system inactivity. Windows 95 uses the motherboard BIOS to put the processor into SMM. The  
motherboard BIOS in turn invokes the video BIOS to place the monitor into standby mode. Some  
video BIOSes reenable interrupts when they are called but do not ensure that a valid interrupt  
service routine is available. If the video BIOS then generates a hardware or software interrupt  
while the system is in SMM, in most cases the system will lock up.  
3.9 Advanced Power Control (APC)  
The BIOS supports APC through the National 87307 Super I/O controller. Two features that have  
been implemented are Auto Start On AC Loss and Power-On COM1 Ring. Auto Start On AC  
Loss sets the control for returning to the last known state of the computer, or powering down upon  
AC power loss to the motherboard. Power-On COM1 Ring sets the control for allowing the  
computer to be powered on upon an incoming POTS call to a telephony device configured for  
operation on COM1.

Motherboard BIOS and Setup Utility  
3.10 Language Support  
The BIOS setup screen and help messages are supported in 32 languages. There are 5 languages  
available at this time: American English, German, Italian, French, and Spanish. Translation to  
other languages may become available at a later date.  
3.11 Boot Options  
Booting from CD-ROM is supported in adherence to the “El Torito” v. 1.0 bootable CD-ROM  
format specification developed by Phoenix Technologies and IBM. Under the Boot Options field  
in Setup, CD-ROM is one of four possible boot devices which are defined in priority order. The  
default setting is for floppy to be the primary boot device and hard drive to be the secondary boot  
device. If CD-ROM is selected, it must be the first device. The third and fourth devices are set to  
disabled in the default configuration. The user can add also select network as a boot device. The  
network option allows booting from a network add-in card with a remote boot ROM installed.  
NOTE  
A copy of “El Torito” v. 1.0 is available on the Phoenix Web page  
(http://www.ptltd.com/techs/specs.html).  
3.12 Flash LOGO Area  
The motherboard supports a 4 KB programmable flash user area located at E8000-E8FFF. An  
OEM may use this area to display a custom logo. The BIOS accesses the user area just after  
completing POST. A utility is available from Intel to assist with installing a logo into flash for  
display during POST. Contact your local Intel Sales office or authorized distributor for further  
information.  
3.13 Setup Enable Jumper  
A motherboard configuration jumper controls access to the BIOS Setup utility. By setting the  
jumper to the disable position, the user is prevented from accessing the Setup utility during the  
POST or at any other time. The message prompting the user to press <F1> to enter Setup is also  
disabled.  
3.14 Overview of the Setup Menu Screens  
The Setup program initially displays the Main menu screen. In each screen there are options for  
modifying the computer’s configuration. Select a menu screen by pressing the left <> or right  
<> arrow keys. Use the up <> or down <> arrow keys to select items in a screen. Use the  
<Enter> key to select an item for modification. For certain items, pressing <Enter> brings up a  
subscreen. After you have selected an item, use the arrow keys to modify the setting.

Sets a range of memory addresses that will be directed to the ISA bus rather than on-board  
memory. The options are:  
Disabled (default)  
16 KB  
32 KB  
48 KB  
64 KB  
80 KB  
96 KB  
If this is set to Disabled, the ISA Shared Memory Base Address (described below) will not be  
visible.  
This field should be set to Enabled only when a non Plug and Play ISA card (legacy card) that  
requires non-ROM memory space is used. LAN cards that have on-board memory buffers are one  
example of this; video capture cards that have video buffer memory are another.  
By default, allocation of upper memory is as follows: memory from C0000-C7FFF is  
automatically shadowed. (This memory range is typically reserved for video BIOS.) Memory  
from C8000-DFFFFh is initially unshadowed. The BIOS scans this range for any ISA expansion  
card BIOS that may be present and notes the location and size. The BIOS will then autoconfigure  
the PCI and Plug and Play devices, shadowing the ROM requirements (other than video) into the  
area above E0000h until that area is full. It will then assign additional PCI and Plug and Play  
expansion cards to the area between C8000h and DFFFFh. If an ISA legacy card has non-ROM  
memory requirements, the autoconfigure routine may write into an area that is needed by the ISA  
expansion card. The ISA Shared Memory Size parameter signifies the autoconfigure routine that  
this block of memory is reserved and should not be shadowed.  
Shadowing is a technique that copies a block of memory from an add-in card’s ROM to the same  
address in system memory. This provides faster access and achieves higher performance. By  
default, all upper memory is shadowed.  
3.14.10.4 ISA Shared Memory Base Address  
Sets the base address for the ISA Shared Memory. The options are:  
C8000h (default)  
CC000h  
D0000h  
D4000h  
D8000h  
DC000h  
This setting could affect the ISA Shared Memory Size item. The value entered in the ISA Shared  
Memory Size item cannot extend to the E0000h address.  
For example, if a size of 64K is selected, options D4000h, D8000h, and DC000h are not available.  
If the ISA Shared Memory Size is set to Disabled, this field will not appear.

3.14.10.5 IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15  
Sets the status of the IRQ. The options are:  
Available (default)  
Used By ISA Card  
The PCI auto-configuration code looks here to see if these interrupts are available for use by a PCI  
or Plug and Play device.  
If an interrupt is available, the PCI auto-configuration code or the PnP configuration agent can  
assign the interrupt to be used by the PCI or PnP device.  
If your computer contains a legacy ISA agent that uses one of these interrupts, select Used By ISA  
Card for that interrupt. This lets PCI and PnP cards know that the marked interrupts are not  
available for their use.  
NOTE  
IRQ 3, 4, 5, and 7 may not be available in this option, depending on the setting chosen for the  
COM1, COM2 and parallel ports in the Peripheral Configuration Subscreen. IRQ 14 and 15 may  
not be available if the Primary and Secondary IDE ports are enabled.

3.14.12 Security Screen  
This section describes the two access modes that can be set using the options found on the Security  
screen, and then describes the Security screen options themselves.  
3.14.12.1 Administrative and User Access Modes  
The options on the Security screen menu enable you to restrict access to the Setup program by  
enabling you to set passwords for two different access modes: Administrative mode and User  
mode.  
In general, Administrative mode has full access to the Setup fields, whereas User mode has  
restricted access to the options. Thus, by setting separate Administrative and User passwords, a  
system administrator can limit who can change critical Setup values. The actual limitations depend  
on whether either the Administrative or User passwords or both are set.  
To limit access to who can boot the computer, set the User password. This is the password that the  
computer asks for before booting. If only the Administrative password is set, the computer boots  
up without asking for a password. If both passwords are set, you can enter either password to boot  
the computer.  
Table 40 shows the effects of setting the Administrative and User passwords. (The table is for  
reference only, and is not shown on the Security screen.) In the table, the statement “Can change a  
limited number of options” means you can change the date and time, the power management hot  
key, the User password, the security hot key, and unattended start.

3.14.13.4 Set Administrative Password  
Sets the Administrative password. The password can be up to seven alphanumeric characters.  
3.14.14 Exit Screen  
This section describes the different ways to exit and save or not save changes made in the Setup  
program.  
3.14.14.1 Exit Saving Changes  
Saves the changes to CMOS RAM and exits the Setup program. You can also press the <F10> key  
anywhere in the Setup program to initiate this.  
3.14.14.2 Exit Discarding Changes  
Exits the Setup program without saving any changes. This means that any changes made while in  
the Setup program are discarded and NOT SAVED. Pressing the <Esc> key in any of the four  
main screens initiates this activity.  
3.14.14.3 Load Setup Defaults  
Resets all of the Setup options to their defaults. You can also press the <F5> key anywhere in the  
Setup program to initiate this.  
This selection loads the default Setup values from the ROM table.  
3.14.14.4 Discard Changes  
Discards any changes you made during the current Setup session without exiting the program. You  
can also press the <F6> key anywhere in the Setup program to initiate this.  
This selection loads the CMOS RAM values that were present when the computer was turned on.
