Before You Begin

Warning and Caution

WARNING

Disconnect the 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.

Safety and Regulatory Notice

See the Intel®Desktop Boards D845PT and D845BG Product Guide for all

applicable regulatory compliance statements, product certification markings, and

safety and electromagnetic compatibility (EMC) standards and regulations these

desktop boards are 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.

✏ NOTE

The D845PT board layout was used in all illustrations unless otherwise

noted.

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.

Supported Components

Processors

CAUTION

Failure to use an ATX12V power supply, or not connecting the additional

power supply lead to the D845PT or D845BG board may result in damage

to the desktop board and/or power supply.

For more information on the ATX12V power supply, refer to the Intel

Desktop Boards D845PT and D845BG Product Guide on the Intel

Express Installer CD-ROM.

The board supports the following processors:

Type

Designation

System Bus

Frequency

Intel®Pentium®4 processor in

the mPGA-478 pin package

1.4, 1.5, 1.6, 1.7, 1.8,

1.9, and 2.0 GHz

400 MHz

For the latest information on processors supported by the D845PT and

D845BG boards, refer to the Intel customer support World Wide Web site:

http://support.intel.com/support/motherboards/desktop

Installation Steps

1 Installing the I/O Shield

The 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 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 power supply, or not connecting the additional

power supply lead to the D845PT and D845BG boards may result in

damage to the desktop board and/or power supply.

For more information on the ATX12V power supply, refer to the Intel

Desktop Boards D845PT and D845BG Product Guide on the Intel

Express Installer CD-ROM.

Refer to your chassis manual for specific instructions on installing and removing

the board. Secure the board to the chassis standoffs using the screws.
