1.6 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.

When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Otherwise,
conflicts will arise between the two PCI groups, making the system
unstable and the card inoperable.

Clear RTC RAM (CLRTC)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!

CLRTC

P5GPL

P5GPL Clear RTC RAM setting

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.

This connector is for an Ultra DMA 100/66 signal cable. The Ultra DMA

100/66 signal cable has three connectors: a blue connector for the
primary IDE connector on the motherboard, a black connector for an
Ultra DMA 100/66 IDE slave device (optical drive/hard disk drive), and
a gray connector for an Ultra DMA 100/66 IDE master device (hard disk
drive). If you install two hard disk drives, you must configure the
second drive as a slave device by setting its jumper accordingly. Refer
to the hard disk documentation for the jumper settings.

• Pin 20 on the IDE connector is removed to match the covered hole
on the Ultra DMA cable connector. This prevents incorrect insertion
when you connect the IDE cable.

• Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.

2.2 BIOS setup program

This motherboard supports a programmable firmware chip that you can
update using the provided utility described in section
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.

“

2.1 Managing and

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
Default SettingsDefault Settings

Default Settings item under the Exit Menu. See section “2.7 Exit
