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.

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.
