2.4 Central Processing Unit (CPU)

2.4 .1 Ove rv ie w

The motherboard comes with a surface mount LGA775 socket supporting
Intel® processors in the 775-land package. This system is designed for
Intel® Core™2 Duo Desktop processors (65W) and well veried. Any other
processor family higher than 65W may trigger the CPU throttle protection.

• Your boxed Intel® Pentium® 4 LGA775 processor package should
come with installation instructions for the CPU, heatsink, and the
retention mechanism. If the instructions in this section do not match
the CPU documentation, follow the latter.

•

Check your motherboard to make sure that the PnP cap is on the
CPU socket and the socket contacts are not bent. Contact your
retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket contacts/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
contacts resulting from incorrect CPU installation/removal, or
misplacement/loss/incorrect removal of the PnP cap.

2.4 .2 Ins ta ll ing C PU

To install a CPU:

1. Locate the CPU socket on the motherboard.

Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.

2. Press the load lever with your

1. Clea r R TC R A M (CLR T C )
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!

You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.

Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).

The USBPW12 jumper is for the rear USB ports (USB port 1-4). The
USBPW56 jumper is for the internal USB connectors (USB port 5-8)
that you can connect to additional USB ports.

• The USB device wake-up feature requires a power supply that can

provide 500 mA on the +5VSB lead for each USB port; otherwise,

the system would not power up.

• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.

5.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can update

using the provided utility described in section “2.1 Managing and updating your
BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to “Run Setup”. This section explains how to congure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conguration 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 recongure your system using the BIOS Setup program so that the

computer can recognize these changes and record them in the CMOS RAM of the

rmware hub.

The rmware 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 rst 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 “2.7 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.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for
this motherboard. Make sure to choose the right BIOS les according to the

version of your mother board. Refer to your Printed Circuit Board (PCB) for
version information.
