The ASUS Q-Fan technology smartly adjusts the CPU fan speed according  
to the system loading to ensure quiet, cool, and efficient operation. See  
page 4-33 for details.  
ASUS Multi-language BIOS  
The multi-language BIOS allows you to select the language of your choice  
from the available options. The localized BIOS menus allow you to configure  
easier and faster. See page 4-13 for details.  
ASUS MyLogo™  
This feature present in the motherboard allows you to personalize and add  
style to your system with customizable boot logos. See pages 4-36 and  
5-7 for details.  
ASUS Instant Music  
This unique feature allows you to play back audio files even before entering  
the operating system. Just press the ASUS Instant Music special function  
keys and enjoy the music! See pages 4-29 and 5-9 for details.  
C.P.R. (CPU Parameter Recall)  
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to  
the BIOS default settings in case the system hangs due to overclocking.  
When the system hangs due to overclocking, C.P.R. eliminates the need to  
open the system chassis and clear the RTC data. Simply shut down and  
reboot the system, and the BIOS automatically restores the CPU previous  
setting for each parameter.

2.3 Central Processing Unit (CPU)  
The motherboard comes with a surface mount LGA775 socket designed for  
the Intel® Pentium® 4 processor in the 775-land package.  
Your boxed Intel® Pentium® 4 LGA775 processor package should  
come with installation instructions for the CPU, fan and heatsink  
assembly. If the instructions in this section do not match the CPU  
documentation, follow the latter.  
Upon purchase of the motherboard, make sure that the PnP cap is  
on the socket and the socket pins are not bent. Contact your  
retailer immediately if the PnP cap is missing, or if you see any  
damage to the PnP cap/socket pins/motherboard components.  
ASUS will shoulder the cost of repair only if the damage is shipment/  
transit-related.  
Keep the cap after installing the motherboard. ASUS will process  
Return Merchandise Authorization (RMA) requests only if the  
motherboard comes with the cap on the LGA775 socket.  
The product warranty does not cover damage to the socket pins  
resulting from incorrect CPU installation/removal, or misplacement/  
loss/incorrect removal of the PnP cap.  
2.3.1 Installling the CPU  
To install a CPU:  
1. Locate the CPU socket on the motherboard.  
®

Notes on Intel® Hyper-Threading Technology  
This motherboard supports Intel® Pentium® 4 CPUs in the 775-land  
package with Hyper-Threading Technology.  
Hyper-Threading Technology is supported under Windows® XP/2003  
Server and Linux 2.4.x (kernel) and later versions only. Under Linux,  
use the Hyper-Threading compiler to compile the code. If you are  
using any other operating systems, disable the Hyper-Threading  
Technology item in the BIOS to ensure system stability and  
performance.  
Installing Windows® XP Service Pack 1 is recommended.  
Make sure to enable the Hyper-Threading Technology item in BIOS  
before installing a supported operating system.  
For more information on Hyper-Threading Technology, visit  
www.intel.com/info/hyperthreading.  
To use the Hyper-Threading Technology on this motherboard:  
1. Install an Intel® Pentium® 4 CPU that supports Hyper-Threading  
Technology.  
2. Power up the system and enter the BIOS Setup (see Chapter 4: BIOS  
setup). Under the Advanced 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 Technology.  
3. Reboot the computer.

2.3.2 Installling the CPU heatsink and fan  
The Intel® Pentium® 4 LGA775 processor requires a specially designed  
heatsink and fan assembly to ensure optimum thermal condition and  
performance.  
Install the motherboard to the chassis before you install the CPU fan  
and heatsink assembly  
When you buy a boxed Intel® Pentium® 4 processor, the package  
includes the CPU fan and heatsink assembly. If you buy a CPU  
separately, make sure that you use only Intel®-certified  
multi-directional heatsink and fan.  
Your Intel® Pentium® 4 LGA775 heatsink and fan assembly comes in  
a push-pin design and requires no tool to install.  
If you purchased a separate CPU heatsink and fan assembly, make sure  
that a Thermal Interface Material is properly applied to the CPU heatsink  
or CPU before you install the heatsink and fan assembly.  
To install the CPU heatsink and fan:  
1. Place the heatsink on top of the  
installed CPU, making sure that  
the four fasteners match the  
holes on the motherboard.  
Fastener

2.6 Jumpers  
1 . Clear RTC RAM (CLRTC)  
This jumper allows you to clear the Real Time Clock (RTC) RAM in  
CMOS. You can clear the CMOS memory of date, time, and system  
setup parameters by erasing the CMOS RTC RAM data. The onboard  
button cell battery powers the RAM data in CMOS, which include  
system setup information such as system passwords.  
To erase the RTC RAM:  
1. Turn OFF the computer and unplug the power cord.  
2. Remove the onboard battery.  
3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the  
cap on pins 2-3 for about 5~10 seconds, then move the cap back to  
pins 1-2.  
4. Re-install the battery.  
5. Plug the power cord and turn ON the computer.  
6. Hold down the <Del> key during the boot process and enter BIOS  
setup to re-enter data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC  
jumper default position. Removing the cap will cause system boot failure!

4.2 BIOS setup program  
This motherboard supports a programmable firmware chip that you can  
update using the provided utility described in section 4.1 Managing and  
updating your BIOS.”  
Use the BIOS Setup program when you are installing a motherboard,  
reconfiguring your system, or prompted to “Run Setup”. This section  
explains how to configure your system using this utility.  
Even if you are not prompted to use the Setup program, you can change  
the configuration of your computer in the future. For example, you can  
enable the security password feature or change the power management  
settings. This requires you to reconfigure your system using the BIOS  
Setup program so that the computer can recognize these changes and  
record them in the CMOS RAM of the firmware hub.  
The firmware hub on the motherboard stores the Setup utility. When you  
start up the computer, the system provides you with the opportunity to  
run this program. Press <Del> during the Power-On-Self-Test (POST) to  
enter the Setup utility; otherwise, POST continues with its test routines.  
If you wish to enter Setup after POST, restart the system by pressing  
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis.  
You can also restart by turning the system off and then back on. Do this  
last option only if the first two failed.  
The Setup program is designed to make it as easy to use as possible. Being  
a menu-driven program, it lets you scroll through the various sub-menus  
and make your selections from the available options using the navigation  
keys.  
The default BIOS settings for this motherboard apply for most  
conditions to ensure optimum performance. If the system becomes  
unstable after changing any BIOS settings, load the default settings  
to ensure system compatibility and stability. Select the Load  
Default Settings item under the Exit Menu. See section “4.7 Exit  
Menu.”  
The BIOS setup screens shown in this section are for reference  
purposes only, and may not exactly match what you see on your  
screen.
