Intel Desktop Board D845PEBT2 Quick Reference 3
Before You Begin
Warning and Cautions
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 D845PEBT2 Product Guide for all applicable
regulatory compliance statements, product certification markings, and safety and
electromagnetic compatibility (EMC) standards and regulations the 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 D845PEBT2 supports system memory as defined below:
• Up to two 184-pin Double Data Rate (DDR) SDRAM Dual Inline Memory
Modules (DIMMs) with gold-plated contacts. Supported memory
configuration are:
—DDR333: to run DDR333 memory at full speed requires an Intel
Pentium 4 processor with 533 MHz front side bus frequency (FSB).
DDR333 memory will run only at DDR266 speeds when using a
processor with 400 MHz FSB.
—DDR266: requires an Intel Pentium 4 processor with 533/400 MHz
FSB, or Intel Celeron processor with 400 MHz FSB.
• Unbuffered and non-registered single or double-sided DIMMs
• Serial Presence Detect (SPD) memory only
• Non-ECC RAM (ECC memory will run in non-ECC mode)
• 2.5 V memory

✏NOTES
Desktop Board D845PEBT2 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 D845PEBT2 link on this Intel World Wide
Web site:

Installation Steps
1 Installing the I/O Shield
The board comes with an I/O shield that is used to block radio frequency
transmissions, necessary to pass emissions (EMI) certification testing, protect
internal components from dust and foreign objects, and promote 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.

to the board illustration on page 4 for the location of the mounting screw 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

4 Installing Memory Modules
CAUTION
Install memory in the DIMM sockets prior to installing the AGP video card
to avoid interference with the memory retention mechanism.
Desktop Board D845PEBT2’s two DIMM sockets are arranged as DIMM 0 and
DIMM 1, as shown in the following figure. 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 AGP video card if it interferes with the DIMM clips from
being easily opened and closed.
3. Align the small notch at the bottom edge of the DIMM with the key in the
socket.
4. Insert the bottom edge of the DIMM into the socket.
5. Push down on the top edge of the DIMM until the retaining clips snap into
place. Make sure the clips are firmly in place.

5 Installing an AGP Card
CAUTION
Care must be taken when installing an AGP card into an AGP slot.
When installing any AGP card in the desktop board, ensure that it is fully
seated in the AGP connector before you power on the system. If the card
is not fully seated in the AGP connector, an electrical short may result
across the AGP slot pins. Depending on the over-current protection of the
power supply, certain board components and/or traces may be damaged.
✏ NOTE
The D845PEBT2 board is only compatible with 1.5 V AGP cards.
Desktop Board D845PEBT2 has an integrated AGP card retention mechanism
(RM). Follow these instructions to install an AGP card:
1. Observe the precautions in “Before You Begin”on page 3.
2. Place the AGP card in the AGP connector.
3. Press down on the card until it is completely seated in the connector and the
card retention notch snaps into place below the RM.
4. Secure the card’s metal bracket to the chassis back panel with a screw.
Install PCI cards into the PCI bus add-in card connectors on the desktop board.
OM14695
A
To remove the AGP card, reverse steps taken when installing an AGP card.
Before removing the card, make sure to push back on the RM lever (A) until the
retention pin completely clears the notch in the card.

6 Installing the Rear Panel USB 2.0 Adapter
The Intel®boxed desktop board package includes a USB 2.0 adapter. Follow
these instructions to install the rear panel USB 2.0 adapter:
1. Observe the precautions in “Before You Begin”on page 3.
2. Attach the cable end with the connector to the front panel USB 2.0 header
on the desktop board.
