1.6 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. Use a grounded wrist strap or touch a safely grounded object or to a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
5. Before you install or remove any component, ensure that the ATX
power supply is switched off or the power cord is detached from the
power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
When lit, the green LED (SB_PWR1) indicates that the system is ON, in sleep
mode, or in soft-off mode, a reminder that you should shut down the system and
unplug the power cable before removing or plugging in any motherboard
component.
Install only 1.5V AGP cards on this motherboard!

1.7 Motherboard installation
Before you install the motherboard, study the configuration of your chassis to
ensure that the motherboard fits into it. The motherboard uses the micro-ATX form
factor that measures 9.6 inches x 9.6 inches (24.5 cm x 24.5 cm).
1.7.1 Placement direction
When installing the motherboard, make sure that you place it into the chassis in
the correct orientation. The edge with external ports goes to the rear part of the
chassis as indicated in the image below.
1.7.2 Screw holes
Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause you physical injury and damage
motherboard components.
Do not overtighten the screws! Doing so may damage the motherboard.
Place this side towards
the rear of the chassis

1-10 Chapter 1: Product introduction
1.8 Central Processing Unit (CPU)
1.8.1 Overview
The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF)
socket. The socket is designed for the Intel
®
Pentium
®
4 Processor in the 478-pin
package with 512/256KB L2 cache on 0.13 micron process. This processor
supports 533/400MHz front side bus (FSB), and allows data transfer rates of
4.2GB/s and 3.2GB/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.
Gold Mark
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
Notes on Intel
®
