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 Board D850GB/D850GBAL 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 (I.T.E) for home or office use when installed into an appropriate
computer chassis. Other end uses or locations may require further evaluation.

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.

Installation Steps
1 Installing the AGP Card Retention Mechanism
(D850GB only)
CAUTION
Install the AGP card retention mechanism (RM) only when using an
AGP card with a retention notch (A) as shown in the figure below. Use of
the RM with an unnotched card may impair video operation. See the
Intel Desktop Board D850GB/D850GBAL Product Guide on the CD-ROM
for RM removal instructions.
OM10592

Quick Reference
The RM encloses the board’s AGP connector and stabilizes the AGP card.
Place the board (component side up) on a flat, supportive surface, preferably on
the anti-static bag in which the board was shipped in. Follow the steps outlined
below to attach the RM (A) to the AGP connector (B):
1 Locate the AGP connector (J5E1) on the board as shown below. Note
that the board’s silkscreen (C) indicates the correct final position of the
lever (D) on the RM.

3 Push the lever end of the RM in the direction of the arrow until the two
rearmost tabs (E) spread over the end of the AGP connector.
OM10180
4 Push the free end of the RM over the other end of the AGP connector and
press down evenly on both ends of the RM until all four tabs click
underneath the AGP connector. Do not apply unnecessary pressure to
avoid damaging the board.

2 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.

3 Installing the Desktop Board
CAUTION
Failure to use an ATX12V power supply, or not connecting both additional
power supply leads to the D850GB or D850GBAL board may result in
damage to the desktop board.
For more information on the ATX12V power supply, refer to the
Intel Desktop Board D850GB/D850GBAL Product Guide on the CD-ROM.
✏NOTES
Make sure your chassis supports the Intel Pentium 4 processor. You can
determine this by verifying that the standoffs for the processor retention
mechanism are in the correct location on the chassis.
Do not install the four screws around the processor socket at this time.
Refer to your chassis manual for specific instructions on installing and removing
the board. Secure the board to the chassis standoffs using 10 screws. Insert the
screws in the mounting holes shown in the figure below.
