Product Description
1.5.4 IDE Support
The board provides six IDE interface connectors:
• Two parallel ATA IDE connector that supports two devices
• Four serial ATA IDE connectors that support one device per connector
1.5.4.1 Parallel ATE IDE Interface
The IXP 450’s Parallel ATA IDE controller has two bus-mastering Parallel ATA IDE interfaces.
The Parallel ATA IDE interfaces support the following modes:
• Programmed I/O (PIO): processor controls data transfer.
• 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec.
• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates
of up to 33 MB/sec.
• ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of
up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The IXP 450’s
ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to
88 MB/sec.
NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections,
noise, and inductive coupling.
The Parallel ATA IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA
devices using the transfer modes.
For information about Refer to
The location of the Parallel ATA IDE connectors Figure 7, page 38
1.5.4.2 Serial ATA Interfaces
The IXP 450’s Serial ATA controller offers four independent Serial ATA ports with a theoretical
maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a
maximum of four Serial ATA devices. A point-to-point interface is used for host to device
connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices
per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the operating system.
The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard
IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI
Conventional bus resource steering is used. Native mode is the preferred mode for configurations
using the Windows* XP and Windows 2000 operating systems.
Many Serial ATA drives use new low-voltage power connectors and require adaptors or power
supplies equipped with low-voltage power connectors.
For more information, see: http://www.serialata.org/
For information about Refer to
The location of the Serial ATA IDE connectors Figure 7, page 38
1.5.5 Real-Time Clock, CMOS SRAM, and Battery
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When the
computer is plugged in, the standby current from the power supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS
RAM at power-on.
1.6 PCI Express* Connectors

1.11 Power Management
Power management is implemented at several levels, including:
• Software support through Advanced Configuration and Power Interface (ACPI)
• Hardware support:
⎯ Power connector
⎯ Fan connectors
⎯ LAN wake capabilities
⎯ Instantly Available PC technology
⎯ Resume on Ring
⎯ Wake from USB
⎯ Wake from PS/2 devices
⎯ Power Management Event signal (PME#) wake-up support
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. The use of ACPI with this board requires an operating system that
provides full ACPI support. ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices, add-in boards (some add-in boards may
require an ACPI-aware driver), video displays, and hard disk drives
• Methods for achieving less than 15-watt system operation in the power-on/standby
sleeping state
• A Soft-off feature that enables the operating system to power-off the computer
• Support for multiple wake-up events (see Table 8 on page 25)
• Support for a front panel power and sleep mode switch
Table 6 lists the system states based on how long the power switch is pressed, depending on how
ACPI is configured with an ACPI-aware operating system.

1.11.1.1 System States and Power States
Under ACPI, the operating system directs all system and device power state transitions. The
operating system puts devices in and out of low-power states based on user preferences and
knowledge of how devices are being used by applications. Devices that are not being used can be
turned off. The operating system uses information from applications and user settings to put the
system as a whole into a low-power state.
Table 7 lists the power states supported by the board along with the associated system power
targets. See the ACPI specification for a complete description of the various system and power
states.

ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake
events.
1.11.2 Hardware Support
CAUTION
Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and
Instantly Available PC technology features are used. Failure to do so can damage the power
supply. The total amount of standby current required depends on the wake devices supported and
manufacturing options.
The board provides several power management hardware features, including:
• Power connector
• Fan connectors
• LAN wake capabilities
• Instantly Available PC technology
• Resume on Ring
• Wake from USB
• Wake from PS/2 keyboard
• PME# signal wake-up support
• WAKE# signal wake-up support
LAN wake capabilities and Instantly Available PC technology require power from the +5 V
standby line.
Resume on Ring enables telephony devices to access the computer when it is in a power-managed
state. The method used depends on the type of telephony device (external or internal).
NOTE
The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an
operating system that provides full ACPI support.

Product Description
1.11.2.1 Power Connector
ATX12V-compliant power supplies can turn off the system power through system control. When
an ACPI-enabled system receives the correct command, the power supply removes all non-standby
voltages.
When resuming from an AC power failure, the computer returns to the power state it was in before
power was interrupted (on or off). The computer’s response can be set using the Last Power State
feature in the BIOS Setup program’s Boot menu.

1.11.2.2 Fan Connectors
The function/operation of the fan connectors is as follows:
• The fans are on when the board is in the S0 or S1 state.
• The fans are off when the board is off or in the S3, S4, or S5 state.
• Each fan connector is wired to a fan tachometer input of the SMSC SCH5017 I/O controller.
• All fan connectors support closed-loop fan control that can adjust the fan speed or switch the
fan on or off as needed.
• All fan connectors have a +12 V DC connection.

1.11.2.3 LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line for the power supply must be capable of
providing adequate +5 V standby current. Failure to provide adequate standby current when
implementing LAN wake capabilities can damage the power supply.
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN
network adapter monitors network traffic at the Media Independent Interface. Upon detecting a
Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer.
Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in
the following ways:
• The PCI Express WAKE# signal
• The PCI Conventional bus PME# signal for PCI 2.2 compliant LAN designs
1.11.2.4 Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line for the power supply must be capable
of providing adequate +5 V standby current. Failure to provide adequate standby current when
implementing Instantly Available PC technology can damage the power supply.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM)
sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off,
and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a
wake-up device or event, the system quickly returns to its last known wake state. Table 8 on
page 25 lists the devices and events that can wake the computer from the S3 state.
The board supports the PCI Bus Power Management Interface Specification. Add-in boards that
also support this specification can participate in power management and can be used to wake the
computer.
The use of Instantly Available PC technology requires operating system support and PCI 2.2
compliant add-in cards, PCI Express add-in cards, and drivers.
1.11.2.5 Resume on Ring
The operation of Resume on Ring can be summarized as follows:
• Resumes operation from ACPI S1 or S3 states
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation
1.11.2.6 Wake from USB
USB bus activity wakes the computer from ACPI S1 or S3 states.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.11.2.7 Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S1 or S3 state.
1.11.2.8 PME# Signal Wake-up Support
When the PME# signal on the PCI Conventional bus is asserted, the computer wakes from an ACPI
S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).
1.11.2.9 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI
S1, S3, S4, or S5 state.

Only the following connectors have overcurrent protection: back panel USB, front panel USB, and
PS/2.
The other internal connectors are not overcurrent protected and should connect only to devices
inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors
to power devices external to the computer’s chassis. A fault in the load presented by the external
devices could cause damage to the computer, the power cable, and the external devices themselves.
This section describes the board’s connectors. The connectors can be divided into these groups:
• Back panel I/O connectors (see page 37)
• Component-side I/O connectors (see page 38)

•Main power – a 2 x 12 connector. This connector is compatible with 2 x 10 connectors
previously used on Intel Desktop boards. The board supports the use of ATX12V power
supplies with either 2 x 10 or 2 x 12 main power cables. When using a power supply with a
2 x 10 main power cable, attach that cable on the rightmost pins of the main power connector,
leaving pins 11, 12, 23, and 24 unconnected.
•ATX12V power – a 2 x 2 connector. This connector provides power directly to the processor
voltage regulator and must always be used. Failure to do so will prevent the board from
booting.

The board has the following add-in card connectors:
• PCI Express x16: one connector supporting simultaneous transfer speeds up to 8 GBytes/sec.
• PCI Express x1: one PCI Express x1 connector. The x1 interface supports simultaneous
transfer speeds up to 500 MBytes/sec.
• PCI Conventional (rev 2.3 compliant) bus: two PCI Conventional bus add-in card connectors.
The SMBus is routed to PCI Conventional bus connector 2 only (ATX expansion slot 6). PCI
Conventional bus add-in cards with SMBus support can access sensor data and other
information residing on the board.
Note the following considerations for the PCI Conventional bus connectors:
• All of the PCI Conventional bus connectors are bus master capable.
• SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI
Conventional bus add-in boards with SMBus support to access sensor data on the board. The
specific SMBus signals are as follows:
⎯ The SMBus clock line is connected to pin A40.

2.8 Jumper Block
CAUTION
Do not move the jumper with the power on. Always turn off the power and unplug the power cord
from the computer before changing a jumper setting. Otherwise, the board could be damaged.
Figure 10 shows the location of the jumper block. The jumper block determines the BIOS Setup
program’s mode. Table 28 describes the jumper settings for the three modes: normal, configure, and
recovery. When the jumper is set to configure mode and the computer is powered-up, the BIOS
compares the processor version and the microcode version in the BIOS and reports if the two match.
The board is designed to fit into either a microATX or an ATX-form-factor chassis. Figure 11
illustrates the mechanical form factor of the board. Dimensions are given in inches [millimeters].
The outer dimensions are 9.60 inches by 8.60 inches [243.84 millimeters by 218.44 millimeters].

2.9.2 I/O Shield
The back panel I/O shield for the board must meet specific dimension and material requirements.
Systems based on this board need the back panel I/O shield to pass certification testing.
Figure 12 shows the I/O shield. Dimensions are given in millimeters [inches].
The figure also indicates the position of each cutout. Additional design considerations for I/O
shields relative to chassis requirements are described in the ATX specification.
NOTE
The I/O shield drawing in this document is for reference only. An I/O shield compliant with the
ATX chassis specification 2.03 is available from Intel.
Table 29 lists the DC loading characteristics of the board. This data is based on a DC analysis of
all active components within the board that impact its power delivery subsystems. The analysis
does not include PCI add-in cards. Minimum values assume a light load placed on the board that is
similar to an environment with no applications running and no USB current draw. Maximum
values assume a load placed on the board that is similar to a heavy gaming environment with a
500 mA current draw per USB port. These calculations are not based on specific processor values
or memory configurations but are based on the minimum and maximum current draw possible from
the board’s power delivery subsystems to the processor, memory, and USB ports.
Use the datasheets for add-in cards, such as PCI, to determine the overall system power
requirements. The selection of a power supply at the system level is dependent on the system’s
usage model and not necessarily tied to a particular processor speed.

Maximum loading 480 W 20.1 A 19.3 A 25 A 0.1 A 2.3 A
2.10.2 Add-in Board Considerations
The board is designed to provide 2 A (average) of +5 V current for each add-in board. The total
+5 V current draw for the board is as follows: a fully loaded D101GGC board (all three expansion
slots and the PCI Express x16 add-in card connector filled) must not exceed 8 A.

2.10.3 Fan Connector Current Capability
CAUTION
The processor fan must be connected to the processor fan connector, not to a chassis fan
connector. Connecting the processor fan to a chassis fan connector may result in onboard
component damage that will halt fan operation.
Table 30 lists the current capability of the fan connectors.

Processor fan 3000 mA
Front chassis fan 1500 mA
Rear chassis fan 1500 mA
2.10.4 Power Supply Considerations
Technical Reference
CAUTION
The +5 V standby line for the power supply must be capable of providing adequate +5 V standby
current. Failure to do so can damage the power supply. The total amount of standby current
required depends on the wake devices supported and manufacturing options.
System integrators should refer to the power usage values listed in Table 29 when selecting a power
supply for use with the board.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the following recommendations found in the indicated
sections of the ATX form factor specification.
• The potential relation between 3.3 VDC and +5 VDC power rails
A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a
requirement. Use a processor heatsink that provides omni-directional airflow (similar to the type
shown in Figure 13) to maintain required airflow across the processor voltage regulator area.
OM16996
Figure 13. Processor Heatsink for Omni-directional Airflow
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the processor
and/or voltage regulator or, in some instances, damage to the board. For a list of chassis that have
been tested with Intel desktop boards please refer to the following website:
All responsibility for determining the adequacy of any thermal or system design remains solely with
the reader. Intel makes no warranties or representations that merely following the instructions
presented in this document will result in a system with adequate thermal performance.
CAUTION
Ensure that the ambient temperature does not exceed the board’s maximum operating temperature.
Failure to do so could cause components to exceed their maximum case temperature and
malfunction. For information about the maximum operating temperature, see the environmental
specifications in Section 2.13.

3.9 BIOS Security Features ...............................................................................................67
3.1 Introduction
The boards use an Intel BIOS that is stored in the Firmware Hub (FWH) and can be updated using a
disk-based program. The FWH contains the BIOS Setup program, POST, the PCI autoconfiguration utility, and Plug and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision code. The
initial production BIOSs are identified as GC11010N.86A.
When the BIOS Setup configuration jumper is set to configure mode and the computer is poweredup, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the
two match.
The BIOS Setup program can be used to view and change the BIOS settings for the computer. The
BIOS Setup program is accessed by pressing the <Del> key after the Power-On Self-Test (POST)
memory test begins and before the operating system boot begins. The menu bar is shown below.
Maintenance Main Advanced Security Power Boot Exit
NOTE
The maintenance menu is displayed only when the Desktop Board is in configure mode. Section 2.8
on page 45 shows how to put the Desktop Board in configure mode.

3.2 BIOS Flash Memory Organization
The Firmware Hub (FWH) includes a 4 Mbit (512 KB) flash memory device.
3.3 Resource Configuration
3.3.1 PCI Autoconfiguration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards.
Autoconfiguration lets a user insert or remove PCI cards without having to configure the system.
When a user turns on the system after adding a PCI 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.
3.3.2 PCI IDE Support
If you select Auto in the BIOS Setup program, the BIOS automatically sets up the
PCI IDE connector with independent I/O channel support. The IDE interface supports hard drives
up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape
drives, and Ultra DMA drives. The interface also supports second-generation SATA drives. The
BIOS determines the capabilities of each drive and configures them 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
62
Page 63
Overview of BIOS Features
on the capability of the drive. You can override the auto-configuration options by specifying
manual configuration in the BIOS Setup program.
To use ATA-66/100 features the following items are required:
• An ATA-66/100 peripheral device
• An ATA-66/100 compatible cable
• ATA-66/100 operating system device drivers
NOTE
Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For
example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.
3.4 System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in
a managed network.
The main component of SMBIOS is the Management Information Format (MIF) database, which
contains information about the computing system and its components. Using SMBIOS, a system
administrator can obtain the system types, capabilities, operational status, and installation dates for
system components. The MIF database defines the data and provides the method for accessing this
information. The BIOS enables applications such as third-party management software to use
SMBIOS. The BIOS stores and reports the following SMBIOS information:
• BIOS data, such as the BIOS revision level
• Fixed-system data, such as peripherals, serial numbers, and asset tags
• Resource data, such as memory size, cache size, and processor speed
• Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems, such as Windows NT*, require an additional interface for
obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such
operating systems. Using this support, an SMBIOS service-level application running on a
non-Plug and Play operating system can obtain the SMBIOS information.
3.5 Legacy USB Support
Legacy USB support enables USB devices to be used even when the operating system’s USB
drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and
to install an operating system that supports USB.
Legacy USB support operates as follows:
1. When you apply power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and
configure the BIOS Setup program and the maintenance menu.
5. The operating system loads. While the operating system is loading, USB keyboards and mice
are recognized and may be used to configure the operating system.
6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are
recognized by the operating system, and Legacy USB support from the BIOS is no longer used.
To install an operating system that supports USB, follow the operating system’s installation
instructions.
3.6 BIOS Updates
The BIOS can be updated using the AwardBIOS for Intel® Flash Utility that is available on the
Intel World Wide Web site. The AwardBIOS for Intel Flash Utility requires creation of a boot
diskette and manual rebooting of the system. Using this utility, the BIOS can be updated from a
file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM.
The utility verifies that the updated BIOS matches the target system to prevent accidentally
installing an incompatible BIOS.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS update.
For information about Refer to
The Intel World Wide Web site Section 1.2, page 14
3.6.1 Language Support
The BIOS Setup program and help messages are supported in US English. Check the Intel website
for additional languages as they become available.
3.6.2 Custom Splash Screen
During POST, an Intel® splash screen is displayed by default. This splash screen can be augmented
with a custom splash screen. A tool is available at the Intel website than can be used to create a
custom splash screen.
NOTE
If you add a custom splash screen, it will share space with the Intel branded logo.
For information about Refer to
The Intel World Wide Web site Section 1.2, page 14

Page 65
Overview of BIOS Features
3.7 Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives,
CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device,
the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled.
3.7.1 CD-ROM Boot
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format
specification. Under the Boot menu in the BIOS Setup program, ATAPI CD-ROM is listed as a
boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD
in the CD-ROM drive, the system will attempt to boot from the next defined drive.
3.7.2 Network Boot
The network can be selected as a boot device. This selection allows booting from the onboard LAN
or a network add-in card with a remote boot ROM installed.
3.7.3 Booting Without Attached Devices
For use in embedded applications, the BIOS has been designed so that after passing the POST, the
operating system loader is invoked even if the following devices are not present:
• Video adapter
• Keyboard
• Mouse
3.7.4 Changing the Default Boot Device During POST
Pressing the <F8> key during POST causes a boot device menu to be displayed. This menu
displays the list of available boot devices (as set in the BIOS setup program’s Boot Device Priority
Submenu). Table 39 lists the boot device menu options.
Table 39. Boot Device Menu Options
Boot Device Menu Function Keys Description
<↑> or <↓>
<Enter> Exits the menu, saves changes, and boots from the selected device
<Esc> Exits the menu without saving changes
The following techniques help improve system boot speed:
• Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds,
that minimize hard drive startup delays.
• Select a CD-ROM drive with a fast initialization rate. This rate can influence POST
execution time.
• Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode
changes in POST. These features may add time to the boot process.
• Try different monitors. Some monitors initialize and communicate with the BIOS more
quickly, which enables the system to boot more quickly.
3.8.2 BIOS Boot Optimizations
Use of the following BIOS Setup program settings reduces the POST execution time.
In the Boot Menu:
• Set the hard disk drive as the first boot device. As a result, the POST does not first seek a
diskette drive, which saves about one second from the POST execution time.
• Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several
seconds of painting complex graphic images and changing video modes.
In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can
reduce up to four seconds of option ROM boot time.
NOTE
It is possible to optimize the boot process to the point where the system boots so quickly that the
Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives
with minimum initialization times can also contribute to a boot time that might be so fast that
necessary logo screens and POST messages cannot be seen.
This boot time may be so fast that some drives might be not be initialized at all. If this condition
should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds
(using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu
of the BIOS Setup program).

Overview of BIOS Features
3.9 BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program and who can
boot the computer. A supervisor password and a user password can be set for the BIOS Setup
program and for booting the computer, with the following restrictions:
• The supervisor password gives unrestricted access to view and change all the Setup options in
the BIOS Setup program. This is the supervisor mode.
• The user password gives restricted access to view and change Setup options in the BIOS Setup
program. This is the user mode.
• If both the supervisor and user passwords are set, users can enter either the supervisor password
or the user password to access Setup. Users have access to Setup respective to which password
is entered.
• Both the supervisor and user passwords can be set to boot the system or enter the BIOS setup
menu.
• For enhanced security, use different passwords for the supervisor and user passwords.
• Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 8 characters in
length.
Table 40 shows the effects of setting the supervisor password and user password. This table is for
reference only and is not displayed on the screen.
Table 40. Supervisor and User Password Functions
Password Set Supervisor Mode User Mode
Neither Can change all options
Supervisor only Can change all options Can change a limited number of options
Supervisor and user set Can change all options Can change a limited number of options
Note: If no password is set, any user can change all Setup options.
During the 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 a PCI bus 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.
Table 42 lists the Port 80h POST codes.
NOTE
The POST card must be installed in PCI bus connector 1.
