Motherboard Description
1.5 I/O Shield
The back panel I/O shield for the PD440FX motherboard must meet specific dimensional and
material requirements. Systems based on this motherboard need the back panel I/O shield in order
to pass certification testing. Figure 3 shows the critical dimensions of the chassis-dependent I/O
shield. Figure 4 shows the critical dimensions of the chassis-independent I/O shield. Both figures
indicate the position of each cutout. Additional design considerations for I/O shields relative to
chassis requirements are described in the ATX specification. See Section 6.2 for information about
the ATX specification.
NOTE
✏
An I/O shield specifically designed for the Intel ATX chassis is available from Intel.

Motherboard Description
1.6 Microprocessor
The motherboard supports a single Pentium II processor operating at 2.1 V to 3.5 V. The
motherboard’s voltage regulator is automatically programmed by the processor’s VID pins to
provide the required voltage. The motherboard operates with processors that run internally at
233 or 266 MHz and have either a 256 KB or 512 KB second-level cache.
The processor implements the MMX technology and maintains full backward compatibility with
the 8086, 80286, Intel386, Intel486, Pentium processor, and Pentium Pro processors. The
processor’s numeric coprocessor significantly increases the speed of floating-point operations and
complies with ANSI/IEEE standard 754-1985.
1.6.1 Microprocessor Packaging
The processor is packaged in an S.E.C. cartridge. The S.E.C. cartridge includes the processor core,
the second-level cache, a thermal plate, and a back cover.
The processor connects to the motherboard through the Slot 1 processor connector, a 242-pin edge
connector. When the processor is mounted in Slot 1, it is secured by a retention mechanism
attached to the motherboard. The processor’s heat sink is stabilized by a heat-sink support that is
attached to the motherboard.
1.6.2 Second Level Cache
The second-level cache is located on the substrate of the S.E.C. cartridge. The cache includes burst
pipelined synchronous static RAM (BSRAM) and tag RAM. There can be two or four BSRAM
components totaling 256 KB or 512 KB in size. All supported onboard memory can be cached.
15
PD440FX Technical Product Specification
1.7 Main Memory
The motherboard has four SIMM sockets arranged in two banks: bank 0 and bank 1. Each bank
has two sockets and provides a 64/72-bit wide data path. SIMMs in the same bank must be the
same type (EDO, nonparity, parity, ECC), size, and speed; SIMMs in different banks may differ in
type, size, and speed. SIMMs must be installed in both sockets of a bank, and at least one bank
must be filled for the motherboard to work. The minimum memory size is 8 MB, and the
maximum size is 256 MB. The BIOS automatically detects memory type and size, so no jumper
settings are required.
The motherboard supports the following:
• 72-pin SIMM modules with tin-plated contacts only
• 50 ns or 60 ns DRAM speed only
• EDO SIMMs only
• Nonparity, parity, or ECC SIMMs
• 5 V-memory only
• Single- or double-sided SIMMs
The motherboard supports SIMMs in the following sizes:
Table 1. SIMM Sizes and Configurations
SIMM Size Nonparity Configuration Parity and ECC Configuration
4 MB 1 x 32 1 x 36
8 MB 2 x 32 2 x 36
16 MB 4 x 32 4 x 36
32 MB 8 x 32 8 x 36
64 MB 16 x 32 16 x 36
1.7.1 EDO DRAM
EDO DRAM improves memory-read performance by holding the memory data valid until the next
falling edge of the CAS# signal. With EDO DRAM, the CAS# precharge overlaps the data-valid
time, which allows the CAS# signal to negate earlier while still satisfying the memory data-valid
window.

Motherboard Description
1.7.2 Parity/ECC DRAM
Memory error checking and correction supports the following operations:
• Parity memory operationdetects single-bit errors but does not correct the errors.
• Error checking and correcting (ECC) operationdetects single-bit and double-bit errors, and
corrects single-bit errors.
Use parity and ECC memory as follows:
• Parity and ECC SIMMs must not be mixed in the same bank.
• The 82441FX (PMC) memory controller automatically detects the presence of parity and ECC
SIMMs (36-bit modules) and treats them identically.
• Parity and ECC operations are supported with parity or ECC SIMMs.
• Use the Setup program to enable parity or ECC support. See Section 4.2.32 for information
about enabling parity or ECC support.
• If any nonparity SIMMs are installed, the memory operates in nonparity mode only. The Setup
options for selecting parity or ECC mode do not appear.
The following table describes the effect of using Setup to put each memory type in each supported
mode. Whenever ECC mode is selected in Setup, some loss in memory performance occurs.

PD440FX Technical Product Specification
The keyboard controller also supports the following hot-key sequences:
• <Ctrl><Alt><Del>: Software reset. This key sequence resets the computer’s software by
jumping to the beginning of the BIOS code and running the power-on self test (POST).
• <Ctrl><Alt><defined in Setup>: Power management. This key sequence invokes powermanaged mode, which reduces the computer’s power consumption while maintaining its ability
to service external interrupts.
• <Ctrl><Alt><defined in Setup>: Keyboard lock. This key sequence is a security feature that
locks the keyboard until the user password is entered. When keyboard lock is invoked, the
keyboard LEDs flash. To enable the keyboard-lock feature, a user password must be specified

Motherboard Description
1.12.1 Power Supply Connector
When used with a power supply that supports remote power on/off, the motherboard can turn off
the system power through software control.
To enable soft-off control in software, advanced power management must be enabled in the Setup
program and in the operating system. When the system BIOS receives the correct APM command
from the operating system, the BIOS turns off power to the computer. For example, in the
Windows 95 Start menu, select Shutdown to turn off the power.
With Auto Start On AC loss enabled in the Setup program and soft-off enabled, if power to the
computer is interrupted by a power outage or a disconnected power cord, when power resumes, the
computer returns to the on or off state it was in before power was interrupted.

pin to ground for at least 50 ms to signal the power supply to switch on or off. (The time
requirement is due to the motherboard’s internal debounce circuitry.) At least two seconds must
pass before the motherboard will recognize another on/off signal.
1.12.2.2 Sleep/Resume Header
When APM is enabled in the system BIOS and the operating system’s APM driver is loaded, the
system can enter sleep (standby) mode in one of three ways:
• Optional front panel sleep/resume button
• Hot-key defined in the Setup program
• System inactivity timeout
Default timeout is 10 minutes
Can be changed in the Setup program
A sleep/resume switch is supported by the 2-pin header located on the front panel I/O connector.
The front panel sleep/resume switch must be a momentary SPST type that is normally open.
Closing the sleep/resume switch generates a system management interrupt (SMI) to the processor;
the processor immediately goes into system management mode (SMM). While in sleep mode, the
system is fully capable of responding to and servicing external interrupts (such as an incoming fax)
even though the monitor turns on only if a keyboard or mouse interrupt occurs. To resume system
activity, press the sleep/resume button again, use the keyboard, or use the mouse.
1.12.2.3 Infrared Connector
The Serial Port 2 can be configured to support an IrDA module connected to this 6-pin header.
After configuring the IrDA interface, files can be transferred to or from portable devices such as
laptops, PDAs, and printers using application software.
1.12.2.4 Onboard IDE Hard Disk LED (HD LED) Header
This header can be connected to an LED to provide a visual indicator that data is being read from
or written to an IDE hard drive. For the LED to function properly, the IDE drive must be
connected to the onboard IDE controller on the motherboard. See Section 1.12.3 for information
about the header for an add-in hard-drive controller card.
1.12.2.5 Sleep/Power LED Header
You can connect this header to an LED that will light when the computer is powered on. This
LED will also blink when the computer is in a power-managed state.
1.12.2.6 Reset Header
You can connect this header to a momentary SPST type switch that is normally open. When the
switch is closed, the board resets and runs the POST.
34
Motherboard Description
1.12.2.7 Speaker Header
A speaker may be installed on the motherboard as a manufacturing option. The speaker option
includes a jumper on pins 26-27 of the front panel connector. You can disable the onboard speaker
by removing the jumper, and you can connect an offboard speaker in its place. The speaker
(onboard or offboard) provides error beep code information during the POST in the event that the
computer cannot use the video interface. The speaker is not connected to the audio subsystem and
does not receive output from the audio subsystem.
1.12.3 Hard Drive LED (HDD LED) Header
The hard drive LED header is a 1 x 2-pin header (J6F1) that allows add-in controller applications
(i.e., a SCSI controller for additional drive capacity) to use the same LED as the onboard frontpanel LED. This header can be connected to the LED output of the add-in controller card. The
LED will indicate when data is being read or written using the add-in controller. See
Section 1.12.2.4 for information about the onboard IDE hard disk LED header.

1.14 Reliability
The Mean-Time-Between-Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction
Procedure, TR-NWT-000332, Issue 4, September 1991.
The MTBF prediction is for:
• Early identification of redesign or alternate component selection if cumulative failure rates
exceed reliability expectations.
• Reliability information for field service personnel to estimate repair rates and spares
requirements.
MTBF data is calculated from predicted data @ 55 °C.
The MTBF prediction for the PD440FX motherboard is 55,763 hours.

Windows 95 desktop, APM enabled, in SMM 28.0 W
1.16.1 Power Supply Considerations
For typical configurations, the motherboard is designed to operate with at least a 200 W power
supply (see Section 6.2 for the specification). A higher-wattage power supply should be used for
heavily-loaded configurations. The power supply must meet the following requirements:
• Rise time for power supply: 2 ms to 20 ms
• Minimum delay for reset to Power Good: 100 ms
• Minimum Powerdown warning: 1 ms
• 3.3 V output must reach its minimum regulation level within ± 20 ms of the +5 V output
reaching its minimum regulation level

The following table provides maximum component case temperatures for motherboard components
that may be sensitive to thermal changes. Case temperatures may be affected by the motherboard’s
operating temperature, current load, or operating frequency. Maximum case temperatures are
important when considering proper airflow to cool the motherboard.
CAUTION
An ambient temperature that exceeds the motherboard’s maximum operating temperature by 5 oC
o
C may cause components to exceed their maximum case temperature. For information about

2.6 PCI Interrupt Routing Map
This section describes interrupt sharing and how the interrupt signals are connected between the
motherboard’s PCI expansion slots and onboard PCI devices. The PCI specification specifies how
interrupts can be shared between devices attached to the PCI bus. In most cases, the small amount
of latency added by interrupt sharing does not affect the operation or throughput of the devices. In
some special cases where maximum performance is needed from a device, a PCI device should not
share an interrupt with other PCI devices. Use the following information to avoid sharing an
interrupt with a PCI add-in card.
PCI devices are categorized as follows to specify their interrupt grouping:
• INTA: By default, all add-in cards that require only one interrupt are in this category. For
almost all cards that require more than one interrupt, the first interrupt on the card is also
classified as INTA.
• INTB: Generally, the second interrupt on add-in cards that require two or more interrupts is
classified as INTB. (This is not an absolute requirement.)
• INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC and a
fourth interrupt is classified as INTD.
The PIIX3 PCI-to-ISA bridge has four programmable interrupt request (PIRQ) input signals. Any
PCI interrupt source (either onboard or from a PCI add-in card) connects to one of these PIRQ
signals. Because there are only four signals, some PCI interrupt sources are mechanically tied
together on the motherboard and therefore share the same interrupt. Table 40 lists the PIRQ
signals and shows how the signals are connected to the PCI expansion slots and to onboard PCI
interrupt sources.
Table 40. PCI Interrupt Routing Map

For example, assume that you plug an add-in card that has one interrupt (group INTA) into the
fourth PCI slot. In this slot, an interrupt source from group INTA connects to the PIRQD signal
that is already connected to the onboard USB PCI sources. The add-in card shares an interrupt
with these onboard interrupt sources.
55
PD440FX Technical Product Specification
Now, however, plug an add-in card that has one interrupt (group INTA) into the first PCI slot.
Plug a second add-in card that has two interrupts (groups INTA and INTB) into the second PCI
slot. INTA in the first slot is connected to signal PIRQA. INTA in the second slot is connected to
signal PIRQB, and INTB is connected to signal PIRQC. With no other cards added, the three
interrupt sources on the first two cards each have a PIRQ signal to themselves. Typically, they will
not share an interrupt.
NOTE
✏
The PIIX3 can connect each PIRQ line internally to one of the IRQ signals (3,4,5,7,9,11,14,15).
Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in
certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be
connected to the same IRQ signal.

3 Overview of BIOS Features
3.1 Introduction
The motherboard uses an Intel/AMI BIOS, which is stored in flash memory and can be upgraded
using a disk-based program. In addition to the BIOS, the flash memory contains the Setup
program, POST, APM, the PCI autoconfiguration utility, and Windows 95-ready Plug and Play.
See Section 6.2 for the supported versions of the APM, PCI, and Plug and Play specifications.
This motherboard supports system BIOS shadowing, which allows 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 on the motherboard is identified as 1.00.XX.DT0_.
Information on BIOS functions can be found in the IBM PS/2 and Personal Computer BIOS
Technical Reference published by IBM, and the ISA and EISA Hi-Flex AMIBIOS Technical
Reference published by AMI. Both manuals are available at most technical bookstores.
3.1.1 BIOS Upgrades
Flash memory simplifies distributing BIOS upgrades. You can install a new version of the BIOS
from a disk. BIOS upgrades can be downloaded from the Intel World Wide Web site. See
Section 6.1 for information about this site.
There are two disk-based utilities available from Intel for upgrading the BIOS in flash memory:
FMUP.EXE and iFLASH.EXE. These utilities can do the following during BIOS upgrades:
• Update the flash BIOS from a file on a disk
• Copy the current BIOS code from the flash EEPROM to a disk file as a backup in the event
that an upgrade cannot be successfully completed
• Compare the BIOS in the flash memory with a file to make sure the system has the correct
version
The upgrade utility makes sure that the upgrade BIOS matches the target system to prevent
accidentally installing a BIOS for a different type of system.
NOTE
✏
Before attempting a BIOS upgrade, please review the instructions distributed with the upgrade
utility.
57
PD440FX Technical Product Specification
3.1.2 Autoconfiguration of PCI Devices and Plug and Play Devices
The BIOS automatically configures PCI devices and Plug and Play devices. PCI devices may be
onboard or add-in cards. Plug and Play devices are ISA add-in cards built to meet the Plug and
Play specification. Autoconfiguration lets a user insert or remove PCI or Plug and Play cards
without having to configure the system. When a user turns on the system after adding a PCI or
Plug and Play card, the BIOS automatically configures interrupts, the I/O space, and other system
resources. Any interrupts set to Available in Setup are considered to be available for use by the
add-in card.
PCI interrupts are distributed to available ISA interrupts that have not been assigned to an ISA card
or to system resources. The assignment of PCI interrupts to ISA IRQs is nondeterministic. PCI
devices can share an interrupt, but an ISA device cannot share an interrupt allocated to PCI or to
another ISA device.
Autoconfiguration information is stored in the extended system configuration data (ESCD) format.
See Section 1.13.3 for information about clearing the ESCD area using the CMOS Clear jumper.
For information about the versions of PCI and Plug and Play supported by this BIOS, see
Section 6.2. You can obtain copies of the specifications from the Intel World Wide Web site (see
Section 6.1).
3.1.3 PCI IDE Support
If you select Autoconfiguration in Setup, the BIOS automatically sets up the two local-bus IDE
connectors with independent I/O channel support. The IDE interface supports hard drives up to
PIO Mode 4 and recognizes any ATAPI devices, including CD-ROM drives and tape drives (see
Section 6.2 for the supported version of ATAPI). The BIOS determines the capabilities of each
drive and configures them so as to optimize capacity and performance. To take advantage of the
high capacities typically available today, hard drives are automatically configured for logical block
addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can
override the autoconfiguration options by specifying manual configuration in Setup. The ATAPI
specification recommends that ATAPI devices be configured as shown in Table 41.
Table 41. Recommendations for Configuring an ATAPI Device
Primary Cable Secondary Cable
Configuration Drive 0 Drive 1 Drive 0 Drive 1
Normal, no ATAPI ATA
Disk and CD-ROM for enhanced IDE systems ATA ATAPI
Legacy IDE System with only one cable ATA ATAPI
Enhanced IDE with CD-ROM and a tape or two CD-ROMs ATA ATAPI ATAPI
3.1.4 ISA Plug and Play
If you select in Setup to boot with a Plug and Play operating system (see Section 4.2.42), the BIOS
autoconfigures only ISA Plug and Play cards that are required for booting (IPL devices). If you
select to not boot with a Plug and Play operating system, the BIOS autoconfigures all Plug and
Play ISA cards.
58
Overview of BIOS Features
3.1.5 ISA Legacy Devices
Since ISA legacy devices are not autoconfigurable, the resources for them must be reserved. You
can reserve resources in the Setup program or with an ISA configuration utility. The ISA
configuration utility can be downloaded from the Intel World Wide Web site (see Section 6.1).
System configuration information is stored in ESCD format. See Section 1.13.3 for information
about clearing the ESCD area using the Clear CMOS jumper.
3.1.6 Desktop Management Interface (DMI)
Desktop Management Interface (DMI) is a system management interface for managing computers
in an enterprise environment. The main component of DMI is the management information
format (MIF) database, which contains information about the computing system and its
components. Using DMI, a system administrator can obtain the system types, capabilities,
operational status, installation date and other information about the system components. The DMI
specification requires that certain information about the motherboard be made available to an
application’s program. This information is located in a series of data structures that are accessed in
various ways by the DMI service layer. Component instrumentation allows the service layer to
gain access to information stored in the general-purpose area of nonvolatile memory. The MIF
database defines the data and provides the method for accessing the information.
The BIOS support for DMI enables the maximum benefit from applications such as Intel
LANDesk
Client Manager. The BIOS stores and can report on the following types of DMI
information:
• BIOS data, such as the BIOS revision level
• Fixed-system information, such as data about the motherboard, peripherals, serial numbers, and
asset tags
• Information about the computer discovered during bootup, such as memory size, cache size,
and processor speed
• Dynamic information, such as event detection and error logging
OEMs can use a utility that programs flash memory so the BIOS can report on system and chassis
information. This utility is available through Intel sales offices. See Section 6.1 for information
about contacting your local Intel sales office. See Section 6.2 for information about the latest DMI
specification.
DMI does not work directly under non-Plug and Play operating systems (e.g., Windows NT).
However, the BIOS supports a DMI table interface for such operating systems. Using this support,
a DMI service-level application running on a non-Plug and Play OS can access the DMI BIOS
information.
59
PD440FX Technical Product Specification
3.1.7 Advanced Power Management (APM)
The BIOS supports advanced power management (APM) and standby mode. See Section 6.2 for
the version of the APM specification that is supported. The energy saving standby mode can be
initiated in the following ways:
• Keyboard hot-key sequence specified in Setup
• Time-out period specified in Setup
• Suspend/resume switch connected to the front panel sleep connector
• From the operating system, such as the Suspend menu item in Windows 95
In standby mode, the motherboard reduces power consumption by using the processor’s SMM
capabilities, by spinning down hard drives, and reducing power to or turning off VESA
compliant monitors. In Setup, you can select one of the DPMS modes to use for the monitor:
Standby, Suspend, Sleep, or Disabled (see Section 4.2.37).
While in standby mode, the system retains the ability to respond to external interrupts and service
requests such as incoming faxes or network messages. Any keyboard or mouse activity brings the
system out of standby mode and immediately restores power to the monitor.
APM is enabled in the BIOS by default; however, the system must be configured with an
operating-system-dependent APM driver for the power-saving features to take effect. For example,
Windows 95 enables APM automatically upon detecting the presence of the APM BIOS.
3.1.8 Advanced Power Control (APC)
The BIOS supports advanced power control (APC) with the National Semiconductor PC87307
Super I/O Controller. Two APC features include:
• Auto Start On AC Losssets control for returning to the last known power state of the system.
If AC power is lost while the system is powered up, the system will return to a powered-up
state when AC power is recovered. If AC power is lost while the system is powered off, the
system will remain powered off when AC power is recovered.
• Power-On COM1 Ringsets control that allows the system to be powered on when an
incoming plain old telephone system (POTS) call is received on a telephony device configured
for operation on COM1.
†
DPMS-
3.1.9 Language Support
The Setup program and help messages can be supported in 32 languages. Five languages are
available at this time: American English, German, Italian, French, and Spanish. The BIOS
includes extensions to support the Kanji character set and other non-ASCII character sets.
Translations of other languages may become available at a later date.
The default language is American English, which is always present unless another language is
programmed into the BIOS using the flash memory update utilities. See Section 3.1.1 for
information about the flash memory update utilities.
60
Overview of BIOS Features
3.1.10 Boot Options
In the Setup program, you can choose to boot from a floppy drive, hard drive, CD-ROM, or the
network. The default setting is for the floppy drive to be the primary boot device and the hard
drive to be the secondary boot device. By default the third and fourth devices are disabled.
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format
specification developed by Phoenix Technologies and IBM. See Section 6.2 for information about
the El Torito specification. Under the Boot Options field in the Setup program, CD-ROM is one of
the possible boot devices, which are defined in priority order. If you select CD-ROM as the boot
device, it must be the first device.
You can also select the network as a boot device, which allows booting from a network add-in card
with a remote boot ROM installed.
3.1.11 OEM Logo or Scan Area
The motherboard supports a 4 KB flash-memory user area at memory location E8000-E8FFFh.
You can use this area to display a custom OEM logo during POST, or you can insert an executable
binary image that runs at certain times during the POST. A utility is available from Intel to assist
with installing a logo into flash for display during POST. Contact Intel customer support for
further information. See Section 6.1 for information on contacting Intel customer support.
3.1.12 USB Support
The USB connector on the motherboard allows you to attach any of several USB devices as they
become available. Typically, the device driver for USB devices is managed by the operating
system. However, because keyboard and mouse support may be needed in the Setup program
before the operating system boots, the BIOS supports USB keyboards and mice.
3.1.13 BIOS Setup Access Jumper
You can move the Setup access jumper on the motherboard to enable or disable access to the Setup
utility. The default is for access to be enabled. See Section 1.13.5 for the specific pins on which to
place the jumper.
3.1.14 Recovering the BIOS
Some types of failure can destroy the BIOS. For example, the data can be lost if a power outage
occurs while you are updating the BIOS in flash memory. You can recover the BIOS from a
diskette by changing the setting of the BIOS recovery jumper (see Section 1.13.2).
To create a BIOS recovery diskette, you must make a bootable DOS diskette and place the
recovery files on it. The recovery files are available from Intel, contact Intel customer support for
further information. See Section 6.1 for information on contacting Intel customer support.
61
PD440FX Technical Product Specification
To recover the BIOS, turn off the computer and move the jumper to the BIOS recovery setting.
Insert the bootable BIOS recovery diskette in drive A:. Boot the computer to recover the BIOS.
Two beeps and the end of floppy access to drive A: indicate a successful BIOS recovery. A series
of continuous beeps indicates that the recovery operation failed.
NOTE
✏
No video is displayed during the recovery process.
After a successful recovery, turn off the computer and return the jumper to the original pins to
restore normal operation.
62
4 BIOS Setup Program
The Setup program lets you make basic configuration changes without opening the system chassis.
Setup is accessible only during the POST. To enter the Setup program, press the <F1> key after
the POST memory test has begun and before booting begins. By default, there is a prompt to press
the <F1> key to access Setup, but this prompt may be disabled. See Section 1.13.5 for information
on placing the jumper that prevents user access to the Setup program.
The Setup screens are Main, Advanced, Security, and Exit. The Setup program initially displays
the Main screen. Each screen has options for modifying the system configuration. The following
keys are for navigating the screens:
• The left <←> or right <→> arrow keys select a screen from the menu at the top of the screen.
• The up <↑> and down <↓> arrow keys highlight an item in a screen.
• The <Enter> key selects an item for modification.
• After selecting an item, the left <←> or right <→> arrow keys modify the setting.
• The <Esc> key backs up to the previous screen.
• The <Esc> key at the highest screen exits while discarding changes.
• The <F5> function key resets the options to the BIOS defaults.
• The <F6> function key discards any changes entered during the current setup session.
• The <F10> function key saves all changes and exits.
• For certain items, the <Enter> key brings up a subscreen with its own options. For example,
pressing <Enter> on Floppy Options in the Main screen brings up the subscreen options.
Table 42 lists the screens displayed by the Setup program and lists the section numbers where each
item is described in this document. The final column of the table tells whether you can modify
each option within the Setup program. Fields that cannot be modified are report fields that may
change depending on the system configuration.

78
BIOS Setup Program
4.2.41 Configuration Mode
Sets how the BIOS gets information about ISA cards that do not have Plug and Play capabilities.
The options are:
• Use BIOS Setup (displays options for reserving resources for ISA legacy devices)
• Use PnP OS (displays a choice of operating systems as listed in the following section)
(default)
4.2.42 PnP OS
This option applies only to Plug and Play ISA cards; the BIOS always autoconfigures PCI devices.
The option lets the computer boot with an operating system capable of managing Plug and Play
add-in cards. If you choose either the option Other or Windows 95, the BIOS assigns resources to
ISA Plug and Play initial program load (IPL) devices. The operating system is then responsible to
enable devices and assign resources (i.e., I/O addresses, interrupts) for all remaining devices.
The options are:
• Disabled (for DOS; BIOS configures and enables all devices at boot time, whether or not they
are Plug and Play)
• Other PnP OS (BIOS autoconfigures PCI devices before onboard motherboard devices)
• Windows 95 (BIOS autoconfigures onboard motherboard devices before PCI devices)
(default)
4.2.43 ISA Shared Memory Size
Lets you specify a range of memory addresses that ISA add-in cards can use for shared memory.
These addresses will not be used for shadowing ROM memory from other devices. The options
are:
• Disabled (the ISA Shared Memory Base Address field does not appear) (default)
• 16 KB
• 32 KB
• 48 KB
• 64 KB
• 80 KB
• 96 KB
Enable this field when using a legacy ISA add-in card without Plug and Play capabilities only and
when the card requires memory space that is not in ROM. For example, this could include LAN
cards that have onboard memory buffers or video capture cards that have video-buffer memory.
By default, upper memory is allocated as follows:
• Memory from C0000-C7FFFh is automatically shadowed (this memory range is typically
reserved for video BIOS).
• Memory from C8000-DFFFFh is initially unshadowed.
79
PD440FX Technical Product Specification
The BIOS scans this range for any ISA add-in cards that may be present and notes their location
and size. The BIOS then autoconfigures the PCI devices and Plug and Play devices, shadowing
their ROM requirements (other than video) into the area above E0000h. If that area becomes full,
it continues shadowing to the area between C8000h and DFFFFh. If an ISA legacy card has
memory requirements that are not in ROM, the autoconfigure routine might write into an area that
is needed by the ISA card. Use the ISA Shared Memory Size and ISA Shared Memory Base
Address fields to reserve a block of memory that will not be used for shadowing.
4.2.44 ISA Shared Memory Base Address
Sets the base address for the ISA Shared Memory. The options are:
• C8000h (default)
• CC000h
• D0000h
• D4000h
• D8000h
• DC000h
The options that appear depend on the ISA Shared Memory Size field. The total amount of ISA
shared memory cannot extend to the E0000h address. For example, if you specify a size of 64 KB,
options D4000h, D8000h, and DC000h will not be available.
4.2.45 IRQ 3, 4, 5, 7, 9, 10, 11, 14, 15
Sets the status of the IRQ. The options are:
• Available (default)
• Used By ISA Card
The PCI autoconfiguration code uses these settings to determine whether these interrupts are
available for use by PCI add-in cards. If an interrupt is marked available, the autoconfiguration
code can assign the interrupt to be used by the system. If your computer has an ISA add-in card
that requires an interrupt, select Used By ISA Card for that interrupt.
NOTE
✏
IRQs 5, 9, 10, and 11 are the default user-available IRQs. Depending on the configuration of your
computer, other IRQs may be listed (for example, if you disable the parallel port and/or serial
ports).
4.2.46 Event Log Capacity

Sets a flag that marks all events in the log as having been read the next time the POST runs. The
options are:
• Do Not Mark (events will not be marked as read) (default)
• Mark (all events will be marked as read)
4.2.52 Event Log Subscreens
The bottom of the Event Log screen includes several information fields. These fields display
information about the last event of a specific type and a count of how many events of that type are
logged. Selecting a field and pressing the <Enter> key displays a subscreen that shows information
specific to that type of event. Table 43 lists the event types for which subscreens are available.

An expansion card failed. If the address can be determined, it is displayed as
xxxxx. If not, the message is I/O Card Parity Error ????.
5.5 Port 80h POST Codes
During POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. If the
POST fails, execution stops and the last POST code generated is left at port 80h. This code is
useful for determining the point where an error occurred.
Displaying the POST codes requires the use of an add-in card (often called a POST card). The
POST card can decode the port and display the contents on a medium such as a seven-segment
display. These cards can be purchased from JDR Microdevices or other sources.
The following table provides the POST codes that can be generated by the motherboard’s BIOS.
Some codes are repeated in the table because that code applies to more than one operation.

Code Description of POST Operation Currently In Progress
