Hi-Speed USB 2.0 Support
NOTE
✏
Computer systems that have an unshielded cable attached to a USB port might not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a
shielded cable that meets the requirements for a full-speed USB device.
This desktop board supports up to four USB 2.0 ports via ICH4; two ports routed to the back
panel and two routed to a USB front panel header. USB 2.0 ports are backward compatible with
USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer
rates. Disabling Hi-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may
be required to accommodate operating systems that do not support USB 2.0.
NOTE
✏
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.
Enhanced IDE Interface
The ICH4’s IDE interface handles the exchange of information between the processor and
†
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip
The interface supports:
• Up to four IDE devices (such as hard drives)
• ATAPI devices (such as CD-ROM drives)
• Older PIO Mode devices
• Ultra DMA-33 and ATA-66/100 protocols
• Laser servo (LS-120) drives
drives inside the computer.
Expansion Slots
Desktop Board D845GLVA has three PCI bus add-in card connectors.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be updated by following the instructions in Chapter 3 on page 31.
14
Desktop Board Features
PCI Auto Configuration
If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS
automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that
add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card.
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration
utility in the BIOS automatically detects and configures the device for your computer. You do not
need to run the BIOS Setup program after installing an IDE device. 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
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed
and who can boot the computer. A supervisor password and a user password can be set for the
Setup and for booting the computer, with the following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup options. If
only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives
the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the supervisor
password or the user password to access Setup. Setup options are then available for viewing
and changing depending on whether the supervisor or user password was entered.
• Setting a user password restricts who can boot the computer. The password prompt is
displayed before the computer is booted. If only the supervisor password is set, the computer
boots without asking for a password. If both passwords are set, you can enter either password
to boot the computer.
Power Management Features
• Advanced Configuration and Power Interface (ACPI)
• Suspend to RAM (Instantly Available PC technology)
ACPI
ACPI gives the operating system direct control over the power management and Plug & Play
functions of a computer. The use of ACPI with the desktop board requires an operating system
that provides full ACPI support.
15
Intel Desktop Board D845GLVA Product Guide
Suspend to RAM (Instantly Available PC Technology)
CAUTION
For Instantly Available PC technology, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current. Failure to provide adequate standby current when
using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.
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. When signaled by a
wake-up device or event, the system quickly returns to its last known awake state.
The desktop board’s standby power indicator, shown in Figure 2, is lit when there is standby power
to the system. This includes the memory modules and PCI bus connectors, even when the
computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber.
OM15860
Figure 2. Location of the Standby Power Indicator
CAUTION
Power supplies used with this board must be able to provide enough standby current to support the
standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary
to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity,
the desktop board may lose register settings stored in memory.

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.
When the voltage drops below 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 10 shows the location of the battery.
CAUTION
Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled
where possible. Disposal of used batteries must be in accordance with local environmental
regulations.
PRECAUTION
Risque d'explosion si la pile usagée est remplacée par une pile de type incorrect. Les piles
usagées doivent être recyclées dans la mesure du possible. La mise au rebut des piles usagées doit
respecter les réglementations locales en vigueur en matière de protection de l'environnement.

utility or the Intel
Updating the BIOS with the Intel® Express BIOS Update
Utility
With the Intel Express BIOS Update utility you can update the system BIOS while in the
Windows* environment. The BIOS file is included in an automated update utility that combines
the functionality of the Intel Flash Memory Update Utility and the ease-of use of Windows-based
installation wizards.
To update the BIOS with the Intel Express BIOS Update utility:
2. Navigate to the D845GLVA page, click “[
Express BIOS Update utility file.
3. Download the file to your hard drive. (You can also save this file to a diskette. This is useful
if you are updating the BIOS for multiple identical systems.)
4. Close all other applications. This step is required. Your system will be rebooted at the last
Express BIOS Update window.
5. Double-click the executable file from the location on your hard drive where it was saved. This
runs the update program.
6. Follow the instructions provided in the dialog boxes to complete the BIOS update.
Flash Memory Update Utility, and how to recover the BIOS if an update fails.
view] Latest BIOS updates”, and select the
Updating the BIOS with the Intel® Iflash BIOS Update
Utility
With the Intel® Iflash BIOS update utility you can update the system BIOS from a floppy disk or
other bootable media. The utility available from the Web provides a simple method for creating a
bootable flash memory update floppy that will automatically update your BIOS.
Obtaining the BIOS Update File
You can update to a new version of the BIOS by using the BIOS update file. The BIOS update file
is a compressed self-extracting archive that contains all the files you need to update the BIOS. The
BIOS update file contains:
• New BIOS files
• BIOS recovery files
• Intel Flash Memory Update Utility
You can obtain the BIOS update file through your computer supplier or by navigating to the
D845GLVA page on the Intel World Wide Web site at:
Navigate to the D845GLVA page, click “[view] Latest BIOS updates”, and select the
Intel Iflash BIOS Update utility file.
NOTE
✏
Review the instructions distributed with the update utility before attempting a BIOS update.
The Intel Iflash BIOS update utility allows you to:
• Update the BIOS in flash memory
• Update the language section of the BIOS
Updating the BIOS
CAUTION
The AUTOEXEC.BAT file provided with the update files updates the BIOS. Do not interrupt the
process or the system may not function.
1. Boot the computer with the BIOS update diskette in drive A. During system boot, the
AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update
process.
2. When the update process is complete, the monitor will display a message telling you to remove
the diskette and to reboot the system.
3. As the computer boots, check the BIOS identifier (version number) to make sure the update
was successful. If a logo appears, press
<Esc> to view the POST messages.
Recovering the BIOS
It is unlikely that anything will interrupt the BIOS update, however, if an interruption occurs, the
BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails.
The following procedure uses recovery mode for the Setup program. See page 27 for more
information on Setup modes.
NOTE
✏
Because of the small amount of code available in the boot block area, there is no video support.
You will not see anything on the screen during this procedure. Monitor the procedure by listening
to the speaker and looking at the diskette drive LED.
1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external
peripherals.
2. Remove the computer cover and locate the configuration jumper block (J9H2) (see Figure 9).
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.
3

4. Insert the bootable BIOS update diskette into diskette drive A.
5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to
boot. The recovery process will take a few minutes.
32
Updating the BIOS
6. Listen to the speaker:
• Upon applying power, drive A will begin to show activity. In about a minute, two beeps
are heard and drive A activity ceases (temporarily) indicating the successful recovery of
the BIOS core. Drive A activity will begin again followed by two more beeps indicating
the successful recovery of the boot block. This sequence of events indicates a successful
BIOS recovery.
• A series of continuous beeps indicates a failed BIOS recovery.
7. If recovery fails, return to step 1 and repeat the recovery process.
8. If recovery is successful, turn off the computer, and disconnect its power cord.
9. Remove the computer cover and continue with the following steps.
10. On the jumper block (J9H2), reinstall the jumper back on pins 1-2 as shown below to set
normal mode for Setup.

Board Connectors
The board connectors can be divided into three groups:
• Back panel connectors
• Midboard connectors
— Audio connectors
— Fan headers and power connectors
— Add-in board and peripheral interface connectors
• Internal headers
CAUTION
Many of the midboard and front panel connectors provide operating voltage (+5 V dc and
+12 V dc, for example) to devices inside the computer chassis, such as fans and internal
peripherals. These connectors are not overcurrent protected. Do not use these connectors for
powering devices external to the computer chassis. A fault in the load presented by the external
devices could cause damage to the computer, the interconnecting cable, and the external devices
themselves.
