CAUTION
1.5 V is the recommended and default setting for DDR3 memory voltage. The other
memory voltage settings in the BIOS Setup program are provided for performance
tuning purposes only. Altering the memory voltage may (i) reduce system stability
and the useful life of the system, memory, and processor; (ii) cause the processor and
other system components to fail; (iii) cause reductions in system performance; (iv )
cause additional heat o r other damage; and (v) a ffect system data i ntegrity.
Intel has not tested and does not warranty the operation of the processor beyond its
specifications. For information on the processor warranty, refer to
http://www.intel.com/support/processors/sb/CS-
020033.htm?wapkw=(processor+warranty).
Intel assumes no r esponsibility that the memory installed on the desktop board, if used
with altered clock frequencies and/or voltages, will be fit for any particular purpose.
Check with the memory manufacturer for warranty terms and additional details.
Table 4 lists the supported DIMM configurations.

Note: “DS” refers to double-sided memo ry modules (containing tw o rows of SDR A M) and “SS” refer s to
single-sided memor y modules (containing o ne r ow of SDRAM).
The Intel Core i7 and Intel Xeon processors support the following types of memory
organization:
•Quad channel (Interleaved) mode. This mode offers the highest throughput fo r
real world applicat ions.
•Tri channel (Interleaved) mode. Tri channel mode is enabled when the installed
memory capacities of any three DIMM channels are equal.
•Dual channel (Interleaved) mode. Dual channel mod e is enabled when the
installed memory capacities of both DIMM channels are equal. Technology and
device width can vary from one channel to the other but the installed memory
capacity for each channel must be equal. If different speed DIMMs are used
between channels, the slowest memory timing will be used.
•Single channel (Asy mme tr ic) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed DIMMs are
used between channels, the slowest memory timing will be used.
Intel Desktop Board DX79TO T echnical Product Spec ification
Figure 3 illustrates the memory channel and DIMM configuration.

22
Product Description
1.7 Real-Time Clock Subsystem
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 via the power supply 5V STBY rail.
NOTE
If the battery and AC po w er fail, date and time values will be reset and the user will be
notified during POST.
When the voltage drops b elow a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 13 shows the location of the battery.
1.8 Legacy I/O Controller
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• Intelligent power management, including a programmable wake-up event interface
• PCI power management support
The BIOS Setup program provides configuration options for the I/O controller.
1.8.1 Consumer Infrared (CIR)
The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer
Infrared usage models. Microsoft Windows Vista and Microsoft Windows 7 are the
supported operating systems.
The CIR feature is made up of two separate pieces: the receiving (receiver) header,
and the output (emitter) header. The receiving header consists of a filtered translated
infrared input compliant with Microsoft CI R specifications, and also a “learning”
infrared input. This learning input is simply a high pass input which the computer can
use to “learn” to speak the infrared communication language of other user remotes.
The emitter header consists of two output ports which the PC can use to emulate
“learned” infrared commands in order to control external electronic hardware.
Customers are required to buy or create their own interface modules to p lug into I ntel
Desktop Boards for this feature to work.

Product Description
1.12.1.1 System States and Power States
Under ACPI, the operating system directs all system and device power state
transitions. The opera ting sy stem 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 8 lists the power states supported by the board along with the assoc iate d system
power targets. See the ACPI specification for a complete description of the various
system and power states.

Product Description
1.12.2 Hardware Support
CAUTION
Ensure that the powe r supply provides adequate +5 V standby current if LAN wake
capabilities and Instantly Avai lable PC technology f eatures are used. Failure to do so
can damage the power supply. The total amo unt of standby current required depends
on the wake devices supported and manufac turing options.
The board provides several power management hardware features, including:
• Power connector
• Fan headers
• LAN wake capabilities
• Instantly Available PC technology
• Wake from USB
• PME# signal wake-up support
• WAKE# signal wake-up support
• Wake from Consumer IR
• Wake from S5
• Power Supervisor
• +5 V Standby Power Indicator LED
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line.
NOTE
The use of Wake from USB from an ACPI state requires an operating system that
provides full ACPI support.
1.12.2.1 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.

1.12.2.2 Fan Headers
The function/operation of the fan headers is as follows:
• The fans are on when the board is in the S0 state
• The fans are off when the board is off or in the S3, S4, or S5 state
• Each fan header is wired to a fan tachometer input of the hardware monitoring and
fan control SIO
•All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed
• All fan headers have a +12 V DC connection
• 4-pin fan headers are controlled by Pulse Width Modulation
For information about Refer to
The location of the fan he a d e rs Figure 12, page 46

1.12.2.3 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. Fail ure 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 subsystem PCI bus network adapter monitors network traffic at the Media
Independent Inte rface. 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 suppor ts LAN wake capabilities with ACPI in the following
ways:
• The PCI Express WAKE# signal
• The PCI bus PME# signal for PCI 2.3 co mp liant LAN designs
By Ping
Magic Packet
• The onboard LAN subsystem
34
Product Description
1.12.2.4 Instantly Available PC Technology
CAUTION
For Instantly Available P C 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-toRAM) 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 w ake-up device or event, the system quickly returns to
its last known wake state. Table 9 on page 32 lists the devices and events that can
wake the computer from the S3 state.
The board support s the PCI Bus Power Management Interface Specification. Add-in
boards that also suppor t this s pecification can participate in power managem ent 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.
1.12.2.5 Wake from USB
USB bus activity wakes the computer from an ACPI S3 state.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB and
is supported by the operating system.
1.12.2.6 PME# Signal Wake-up Support
When the PME# signal on the Conventional PCI bus is asserted, the computer wakes
from an ACPI S3, S4, or S5 state (with Wake on PME enabled in the BIOS).
1.12.2.7 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S3, S4, or S5 state.
1.12.2.8 Wake from Consumer IR
CIR activity wakes the computer from an ACPI S3, S4, or S5 state.
1.12.2.9 Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake
from an ACPI S5 state.

1.12.2.10 Power Supervisor
The Power Supervisor actively monitors the input voltages from the power supply and
protects the board and any attached peripherals from electrical overstress and possible
physical damage. The Power Supervisor will activate if it detects the power supply
voltage rails have deviated outside the current ATX po wer supply specification and safe
operating levels.
If the Power Supervisor detects an out of spec voltage, the following will happen:
1. The board will be powered down immediately to protect circuits from electrical
overstress and possible physical damage.
2. A red warning LED on the board will activate as a visual cue.
3. During the next power on, a message will be displayed on the screen to notify the
user that the power supply voltage rails have deviated outside the current ATX
power supply specification and sa fe operating levels.
4. A message will be added to the BIOS Event Lo g for each event that takes place
until the BIOS Event Log is cleared.
1.12.2.11 +5 V Standby Powe r Indicator LED
The +5 V standby power indicator LED shows that power is still present even when the
computer appears to be off.

Product Description
1.13 Board Status LEDs
The Desktop Board provides eight board status LEDs that allow you to monitor the
board’s progress through the BIOS Power-on Self-Test. At initial power on, all the
LEDs are off. When the BIOS starts an activity such as memory initialization, the
corresponding LED starts flashing. Once the a ctivity has completed, the LE D will
remain on. Six additional LEDs can be used to monitor board functions such as hard
drive activity, processor errors, and power faults. Refer to Table 9 for a description of
all of the LEDs. Figure 7 shows the location of the LEDs.

2.1 Memory Resources
2.1.1 Addressable Memory
The board utilizes 64 GB of addressable system memory. Typically the address space
that is allocated for Conventional PCI bus add-in cards, PCI Express configuration
space, BIOS (SPI Flash device), and chipset overhead resides above the top o f DRAM
(total system memory). On a system that has 64 GB of system memory installed, it is
not possible to use all of the installed memory due to system address space being
allocated for other system critical functions. These functions include the following:
• BIOS/SPI Flash device (64 Mbit)
• Local APIC (19 MB)
• Direct Media Interface (40 MB)
• PCI Express configuration space (256 MB)
• PCH base address registers PCI Express ports (up to 256 MB)
• Memory-mapped I/O that is dynamically allocated for Conv entional PCI and PCI
Express add-in cards (256 MB)
The board provides the capability to reclaim the physical memory overlapped by the
memory mapped I/O logical address space. The board remaps physical memory from
the top of usable DRAM bo undary to the 4 GB boundar y to an equivalent sized logical
address range located just above the 4 GB boundary. Figure 9 shows a schematic of
the system memory map. All installed system memory can be used when there is no
overlap of system addresses.

2.2 Connectors and Headers
CAUTION
Only the following connectors and headers have overcurrent protection: back panel
and front panel USB, as well as I EEE 1394a.
The other internal connectors and headers 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 or headers 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.
Furthermore, improper connection of USB or 1394 header single wire connectors may
eventually overload the overcurrent protection and cause damage to the board.
This section describes the board’s connectors. The connectors can be divided into
these groups:
• Back panel I/O connectors
• Component-side I/O connectors and headers (see page 46)

2.5 Electrical Considerations
2.5.1 Power Supply Considerations
CAUTION
The +5 V standby line fr om the power supply must be capable of providing adequate
+5 V standby current. Failure to do so can dam a ge the power supply. The total
amount of standby curr ent required depe nds on the wake devices supported and
manufacturing opt ions.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the indicated parameters of the ATX form factor
specification.
• The potential relation between 3.3 VDC and +5 VDC power rails
• The current capability of the +5 VSB line
• All timing parameters
• All voltage tolerances
For example, for a system consisting of a supported 130 W processor (see section 1.4
on page 16 for a list of supported processors), 8 GB DDR3 RAM, one high end video
card, one hard disk drive, one optical drive, and all board peripherals enabled, the
minimum recommended power supply is 460 W. Table 28 lists the recommended
power supply current values.

2.5.2 Fan Header Current Capability
CAUTION
The processor fan must be connected to the processor fan header, not to a chassis fan
header. Connecting the processor fan to a chassis fan header may result in onboard
component damage that will halt fan operation.
Table 29 lists the current capability of the fan headers.

2.6 Thermal Considerations
CAUTION
A chassis with a maximum internal ambient temperature of 38 oC at the processor fan
inlet is a requirement. Use a processor heat sink that provides omni-directional
airflow to maintain required airflow across the processor voltage regulator area. If a
non omni-directional thermal solution is used customer might ne ed to provide
supplemental cooling to the processor voltage regulator area.
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 hav e been tested with Intel desktop boards p lease 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 2.8.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit.
Failure to do so may result in damage to the voltage regulator circuit. The processor
voltage regulator area (shown in Figure 17) can reach a temperature of up to 85
an open chassis.

3 Overview of BIOS Features
3.1 Introduction
The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash
contains the BIOS Setup program, POST, the PCI auto-configur ation utility, LAN
EEPROM information, and P lug and Play support.
The BIOS displays a message during POST identifying the type o f BIOS and a revision
code. The initial production BIOSs a re identified as SIX7910J.86A.
When the BIOS Setup configuration jumper is set to configure mode and the computer
is powered-up, 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 BIO S settings for the
computer. The BIOS Setup program is accessed by pressing the <F2> key after the
Power-On Self-Test (POST) memory test begins and before the oper a ting sys tem boot
begins. The men u bar is shown below .

3.2 BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 32 Mbit (4096 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.
64
Overview of BIOS Features
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 SMB IOS is the Management Information Format (MIF)
database, which contains information about the computing system and its
components. Using SMBIOS, a system administrator can obta in 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 re quire an additional interface for obtaining the
SMBIOS information. The BIOS supports an S MBIOS 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. Additional
board informat io n can be found in the B IOS under the Additional Information header
under the Main BIOS page.
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 oper ating system that supports USB. By default,
Legacy USB support is set to Enabled.
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.
4. POST completes.
5. The operating system loads. While the operating sys tem is loading, USB keyboards
and mice are recognized and may be used to configure the operating system.
(Keyboards and mice are not recognized during this period if Legacy USB support
was set to Disabled in the BIOS Setup program.)
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.
7. Additional USB legacy feature options can be access by using Intel Integrator
Toolkit.
65
Intel Desktop Board DX79TO T echnical Product Spec ification
To install an operating system that supports USB, verify that Legacy USB support in
the BIOS Setup program is set to Enabled and follow the operating system’s
installa tion ins truct ions.
3.6 BIOS Updates
The BIOS can be updated using either of the follo wing utilities, which are available on
the Intel World Wide Web site:
• Intel
• Intel
• Intel® F7 switch allows a user to select where the BIOS .bio file is located and
®
Express BIOS Update utility, which enables automated updating while in the
Windows environment. Using this utility, the BIOS c an be updated from a file on a
hard disk, a USB drive (a flash drive or a USB hard drive), an optical drive, or from
the file location on the Web.
®
Flash Memory Update Utility, which requires booting from DOS. Using this
utility, the BIOS can be updated from a file on a hard disk, a USB dr ive (a flash
drive or a USB hard drive), or an optical drive.
perform the update from that location/device. Similar to performing a BIOS
Recovery without removing the BIOS configuration jumper.
Both utilities verify that the updated BIOS m a tches the target sy stem to prevent
accidentally installing an incompatible BIOS.
NOTE
Review the instructions distributed with the upgrade utility before a ttempting a BIOS
update.
The BIOS Setup program and help messages are supported in US English. Check the
Intel web site for s upport.

Overview of BIOS Features
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. The Intel Integrator’s Toolkit that is
available from Intel 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.

3.7 BIOS Recovery
It is u nlikely that anything will interrupt a BIOS update; however, if an interruption
occurs, the BIOS could be damaged. Table 34 lists the drives and media types that
can and cannot be used for BIOS recovery. The BIOS recovery media does not need to
be made bootable.
Table 34. Acceptable Drives/Media Types for BIOS Recovery
Media Type Can be used for BIOS recovery?
Optical drive c o nne c te d to the SATA interfac e Yes
USB removable drive (a USB Flash Drive, for example) Yes
USB diskette dr iv e (with a 1.44 MB diskette ) No
USB hard disk drive No
Intel Desktop Board DX79TO T echnical Product Spec ification
3.8 Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard
drive, USB drive, USB flash drive, optical drive, or the network. The default setting is
for the diskette drive to be the first boot device, the hard drive second, and the optical
drive third. If enabled, the last default boot device is the network.
3.8.1 Optical Drive Boot
Booting from the optical drive is supported in compliance to the El Torito boota b le
CD-ROM format specification. U nder the Boot menu in the BIOS Setup program, the
optical drive is listed as a boot device. Boot devices are defined in priority order.
Accordingly, if there is not a bootable CD in the optical drive, the system will attempt
to boot from the next defined drive.
3.8.2 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.
Pressing the <F12> key during POST automatically forces booting from the LAN. To
use this key during POST, the User Access Level in the BIOS Setup program's Security
menu must be set to Full.
3.8.3 Booting Without Attached Devices
For use in embedded applications, the BIOS has been designed so that after passing
the POST, the ope rating system loader is invoked even if the following devices are not
present:
• Video adapter
• Keyboard
• Mouse
3.8.4 Changing the Default Boot Device During POST
Pressing the <F10> key during POST causes a bo ot device menu to be displayed. This
menu displays the list of available bo ot devices (as se t in the B IOS setup program’s
Boot Device Priority Submenu). Table 35 lists the boot device menu options.

Overview of BIOS Features
3.9 Adjusting Boot Speed
These factors affect system b oot speed:
• Selecting and configuring peripherals properly
• Optimized BIOS boot parameters
3.9.1 Peripheral Selection and Configuration
The following techniques help improve sy stem boot speed:
•Choose a hard drive with parameters such as “power-up to data ready” in less than
eight seconds to minimize hard drive startup delays.
•Select an optical drive with a fast initializat ion 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.
3.9.2 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.
•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.
•The BIOS will automat ically not load t he option ROM for the SATA controller if no
drives are installed in it during POST.
NOTE
It is possible to optimize the boot process to the point whe re the system boots so
quickly that the Intel logo screen (or a custom logo splash screen) will not be seen.
Monitors and hard disk drive s 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 shoul d occur, it is pos sible to introduce a pro grammable delay ranging from
zero to 30 seconds by 5 second increments (using the Hard Disk Pre-Delay feature of
the Advanced Menu in the Drive C onfiguration Subm enu of the BIOS Setup program).
69
Intel Desktop Board DX79TO T echnical Product Spec ification
3.10 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 ca n 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 superv isor mode.
•The user password gives restricted access to view and change Setup options in the
BIOS Setup progr am. This is the user mode.
•If only the supervisor password is set, pressing the <Enter> key at the password
prompt of the BIOS Setup program allows the user restricted a ccess to Setup.
•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.
•Setting the user password restricts who can b oot the computer. The password
prompt will be displayed before the computer is booted. If only the supervisor
password is set, the computer boots w ithout asking for a passwor d . If both
passwords are set, the user can enter either password to boot the computer.
•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
16 characters in length.
Table 36 shows the effects of setting the supervisor password and user password. This
table is for reference only and is not displayed on the screen.

4.5 Port 80h POST Codes
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 g enerated 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 ca n d ecode the port a nd display the contents on a medium such as a
seven-segment display.
NOTE
The POST card must be installed in PCI bus connector 1.
The following tables provide information ab out the POST codes generated by the B IOS:
• Table 40 lists the Port 80h POST code ranges
• Table 41 lists the Port 80h POST codes themselves
