1.3 Special features
Latest processor technology
The P4PE-X motherboard supports the latest Intel® Pentium® 4 Processor via a
478-pin surface mount ZIF socket. See page 1-10 for more information.
DDR memory support
Employing the Double Data Rate (DDR) memory technology, the P4PE-X
motherboard supports up to 2GB of system memory using unbuffered non-ECC
PC3200/2700/2100/1600 DDR DIMMs. Memory support depends on the CPU FSB
and DDR type. See page 1-12 for the CPU and DIMM requirements.
Onboard LAN solution
The motherboard has the BroadCom® BCM4401 chipset onboard to support
10BASE-T/100BASE-TX networking protocol.
USB 2.0 technology
The motherboard implements the new Universal Serial Bus (USB) 2.0
specification, extending the connection speed from 12 Mbps on USB 1.1 to a fast
480 Mbps on USB 2.0. See page 1-20.
6-channel digital audio
The ADI AD1980 AC ‘97 audio CODEC is onboard to provide 6-channel audio
playback capability. A digital audio connector is onboard to accommodate the
Sony/Philips Digital Interface (S/PDIF) Out module. See page 1-18.
ASUS EZ Flash BIOS
With the ASUS EZ Flash, you can easily update the system BIOS even before loading
the operating system. No need to use a DOS-based utility or boot from a floppy disk.
C.P.R. (CPU Parameter Recall)
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
This feature allows you to restore the original BIOS data from a floppy disk in
cases when the BIOS codes and data are corrupted. This protection eliminates the
need to buy a replacement ROM chip.

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 standby 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.

Chapter 1: Product introduction
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 ATX form factor
that measures 12 inches x 9 inches (30.5 cm x 22.9 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 seven (7) 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

1.8 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 512KB L2 cache on 0.13 micron process. This processor supports
800*/533/400MHz front side bus (FSB), and allows data transfer rates of 6.4GB/s,
4.2GB/s, and 3.2GB/s, respectively.
If you installed a CPU with 800MHz FSB, you need to use a PC3200 (400MHz)
DDR module.
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.
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
Notes on Intel® Hyper-Threading Technology
1. Hyper-Threading Technology is supported under Windows XP and Linux
2.4.x (kernel) and later versions only. Under Linux, use the Hyper-Threading
compliler to compile the code. If you are using any other operating systems,
disable the Hyper-Threading Techonology item in BIOS to ensure system
stability and performance.
2. It is recommended that you install WinXP Service Pack 1.
Gold Mark
3. Make sure to enable the Hyper-Threading Technology item in BIOS before
installing a supported operating system.
4. For more information on Hyper-Threading Technology, visit www.intel.com/
info/hyperthreading.
To use the Hyper-Threading Technology on this motherboard:
1. Install a Pentium 4 CPU that supports Hyper-Threading Technology.
2. Power up the system and enter BIOS Setup. Under the Boot Menu, make sure
that the item Hyper-Threading Technology is set to Enabled. The item
appears only if you installed a CPU that supports Hyper-Threading
Techonology.
3. Reboot the computer.

Chapter 1: Product introduction
1.8.2 Installing the CPU
Follow these steps to install a CPU.
1. Locate the 478-pin ZIF socket on the motherboard.
2. Unlock the socket by pressing the
lever sideways, then lift it up to a 90°-
100° angle.
Socket Lever
Make sure that the socket lever is lifted
up to 90°-100° angle, otherwise the
CPU does not fit in completely.
3. Position the CPU above the socket
such that its marked corner matches
the base of the socket lever.
90 -100
Gold Mark
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!
