motherboard.

Chapter 2: Hardware setup

2.4 Installing a Central Processing Unit (CPU)

®

2.4.1 Overview

The motherboard comes with a surface mount 478-pin Zero Insertion
Force (ZIF) socket. The socket is designed for the Intel® Pentium® 4
Prescott processor in the 478-pin package with 512KB L2 cache. The
motherboard supports 800/533/400MHz front side bus (FSB), and allows
data transfer rates of up to 6.4GB/s.

Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.

3. Position the CPU above the socket
such that its marked corner
matches the base of the socket
lever.

4. Carefully insert the CPU into the
socket until it fits in place.

The CPU fits only in one correct
orientation. DO NOT force the
CPU into the socket to prevent
bending the pins and damaging
the CPU!

notch so that it fits in only one
direction. DO NOT force a
DIMM into a socket to avoid
damaging the DIMM.

3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the
DIMM is properly seated.

2.8 Installing expansion cards

The system comes with five PCI slots, one AGP slot, and an ASUS
proprietary Wi-Fi slot for installation of expansion cards.

Make sure to unplug the power supply before installing or removing an
expansion card(s). Failure to do so may cause severe damage to both
the motherboard and the components.

To install an expansion card:

1. Before installing the expansion card, read the documentation that
came with it and make the necessary hardware settings for the card.

2. Lay the system on its side on a flat, stable surface.

3. Remove the metal bracket
opposite the slot that you intend
to use. Keep the metal bracket
screw for later use.

4. Align the card connector with the
slot, then press firmly until the
card is completely seated on the
slot.

5. Secure the card with the metal
bracket screw you removed
earlier.
