1.4Special Features
1.4.1 Product highlights
ASUS EZ Flash 
(page 2-2)
With ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required.
C.P.R. (CPU Parameter Recall) 
(page 1-15)
When the system hangs due to overclocking failure, there is no need to open the case to clear the CMOS data. Simply restart the system and the BIOS will automatically restore the CPU default setting for each parameter.
CrashFree BIOS 
(page 2-7)
CrashFree BIOS allows users to restore BIOS data from a floppy diskette even when BIOS code and data are corrupted during upgrade or invaded by a virus. Unlike other competing vendors’ products, ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

1.6Before 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.

1.7Motherboard installation
Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. The motherboard uses the ATX form factor that measures 12 inches x 9.6 inches (30.5 cm x 24.5 cm).
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.
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 ten (10) screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so may damage the motherboard.
Place this side towards the rear of the chassis

1.8Central 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 400MHz front side bus (FSB), and allows a data transfer rate of 3.2GB/s.
Note in the illustration that the CPU has a
Gold Mark
gold triangular mark on one corner. This mark indicates the processor Pin 1 that should match a specific corner of the CPU socket.
Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU!
