Quick Reference
Before You Begin
Warning and Caution
WARNING
Disconnect the desktop board’s power supply from its AC power
source before you connect or disconnect cables, or install or remove
any board components. Failure to do this can result in personal
injury or equipment damage. Some circuitry on the desktop board
can continue to operate even though the front panel power switch
is off.
CAUTION
Electrostatic discharge (ESD) can damage desktop board components.
Install the board at an ESD-controlled workstation. If such a workstation
is not available, wear an antistatic wrist strap or touch the surface of the
antistatic package before handling the board.
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 cables, and the external devices themselves.
Safety and Regulatory Notice
See the Intel Desktop Board D845GVAD2 Product Guide for all applicable
regulatory compliance statements, product certification markings, and safety and
electromagnetic compatibility (EMC) standards and regulations this desktop
board is compliant with.
Replacement battery warning label provided: Place the label inside the chassis
in an easy-to-see location near the battery but not on the board itself.
Intended uses: This product was evaluated as information technology
equipment (ITE) for home or office use when installed into an appropriate
computer chassis. Other end uses or locations may require further evaluation.

Memory Module Requirements
Desktop Board D845GVAD2 supports system memory as defined below:
• Two 184-pin DIMMs
• 2.5 V, 266 MHz or 200 MHz DDR SDRAM interface
• Memory configurations up to 2 GB using 512 Mbit technology
• Serial Presence Detect (SPD)
• Suspend to RAM (STR)
• Non-ECC RAM (registered memory is not supported)
• Unbuffered and non registered single or double-sided DIMMs
The desktop board supports Serial Presence Detect (SPD), suspend to RAM
(STR), and unbuffered, non-ECC RAM (registered memory is not supported).
✏NOTES
The Desktop Board D845GVAD2 has been designed to support DIMMs
based on 512 Mbit technology up to 2 GB, but this technology has not
been validated on this board.
All memory components and DIMMs used with the desktop board must
comply with the PC SDRAM specifications. These include the PC
SDRAM Specification (memory component specific), the PC Unbuffered
DIMM Specification. To view or download these specifications, refer to
this Intel World Wide Web site:
http://www.intel.com/technology/memory/pcsdram/
For information about vendors that support these memory requirements,
refer to the Desktop Board D845GVAD2 link on this Intel World Wide Web
site:

Installation Steps
1 Installing the I/O Shield
The desktop board comes with an I/O shield. When installed in the chassis, the
shield blocks radio frequency transmissions, necessary to pass emissions (EMI)
certification testing, protects internal components from dust and foreign objects,
and promotes correct airflow within the chassis.
Install the I/O shield before installing the desktop board in the chassis. Place the
shield inside the chassis as shown in the following figure. Press the shield into
place so that it fits tightly and securely. If the shield doesn’t fit, obtain a
properly-sized shield from the chassis supplier.
OM13621
2 Installing the Desktop Board
CAUTION
Failure to use an ATX12V or SFX-12V power supply, or not connecting
the additional power supply lead to the Desktop Board D845GVAD2 may
result in damage to the desktop board and/or power supply.
For more information on the ATX12V and SFX-12V power supply, refer to
the Intel Desktop Board D845GVAD2 Product Guide on the Intel Express
Installer CD-ROM.
Refer to your chassis manual for specific instructions on installing and removing
the desktop board. Secure the desktop board to the chassis standoffs using the
screws.
Desktop Board D845GVAD2 is secured to the chassis with six screws. Refer to
the illustration on page 4 for the location of the mounting holes.

3 Installing the Processor
To install the processor, follow these steps:
1. Observe the precautions in “Before You Begin”on page 3.
2. Lift the processor socket lever.
3. Install the processor so that the corner with the triangle marking (A) is
aligned with the corner where the lever is attached to the socket.
4. Lower the lever back to its original position.

5. The desktop board comes with an integrated processor heat sink retention
mechanism (RM). For instructions on how to install the processor fan heat
sink, refer to the boxed processor manual or the Intel customer support
World Wide Web site:
http://support.intel.com/support/processors/pentium4/intnotes478.htm
4 Installing the Memory Modules
CAUTION
Install memory in the DIMM sockets prior to installing a video card in PCI
slot 1 to avoid interference with the memory retention mechanism.
The two DIMM sockets on Desktop Board D845GVAD2 are arranged as
DIMM 0 and DIMM 1, as shown in the figure below. If installing a single
DIMM, install it in DIMM 0.
To install DIMMs, follow these steps:
1. Observe the precautions in “Before You Begin”on page 3.
2. Remove the PCI card from PCI slot 1 if it interferes with the DIMM clips
from being easily opened and closed.
3. Align the small notch in the bottom edge of the DIMM with the key in the
socket.
4. When the DIMM is inserted, push down on the top edge of the DIMM until
the retaining clips snap into place. Make sure the clips are firmly in place.

6 Attaching the IDE Drives
The Intel®boxed desktop board package includes an IDE cable. The cable can
connect two drives to the desktop board. The cable supports the ATA-66/100
(40-contact, 80-conductor) transfer protocol and is backward compatible with
drives using slower IDE transfer protocols.
The cable will work correctly only when oriented as shown in the following
figure. For correct cable function:
1. Observe the precautions in “Before You Begin”on page 3.
2. Attach the cable end with the single connector (A) to the desktop board.
3. Attach the cable end with the two closely spaced connectors (B) to the
drives.

Using the BIOS Setup Program
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 <F2> key
after the Power-On Self-Test (POST) memory test begins and before the
operating system boot begins.

Quick Reference
Setting the BIOS Configuration Jumper Block
CAUTION
Always turn off the power and unplug the power cord from the computer
before changing the jumper block settings. Moving the jumper with the
power on may result in unreliable computer operation.
The BIOS configuration jumper block determines the operating mode of the
BIOS Setup Program and enables BIOS recovery in the event of a failed
BIOS update (see the previous illustration for the location of the jumper block).
The following table describes the jumper block settings for the BIOS Setup
configuration jumper.
BIOS Setup Configuration Jumper Block (J9H2) Settings
Jumper Setting Mode Description
31
Normal (default)
1-2
The BIOS uses the current configuration and
passwords for booting.
31
Configure
2-3
After the Power-On Self-Test (POST) runs, the
BIOS displays the Maintenance Menu. Use this
menu to clear passwords.
31
Recovery
None
The BIOS recovers data from a recovery
diskette in the event of a failed BIOS update.*
*To update or recover the BIOS, see the instructions in the Intel Desktop Board D845GVAD2
Product Guide on the Intel Express Installer CD-ROM.
For a complete list of BIOS Setup settings, see:

Troubleshooting Tips
Desktop Board D845GVAD2 system fails to boot
• Ensure that the power supply cable with the 4-pin connector is plugged into
the 12 V processor core voltage connector located near the processor socket
on the desktop board.
• Remove and re-insert the Intel Pentium 4 processor, memory, and any
add-in cards to make sure they are fully seated. Remove any non-essential
hardware components and boot the system.
• Disconnect all power and remove the CMOS battery. Wait 10 minutes,
then re-install the battery, reconnect power, and boot the system.
A repeating beep error code is heard and the desktop board does not boot
or show any video
This beep code may indicate a problem during detection of the DDR SDRAM
memory device. Check to ensure that system memory is properly installed and
that the DIMMs meet the Memory Module Requirements listed in the Supported
Components section of this document.
Resolving slow boot times
Extended boot time can be the result of IDE drive jumper configuration. For
