information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. 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.

3. Plug the power cord and turn ON the computer.

4. 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!

• If the steps above do not help, remove the onboard battery and move the
jumper again to clear the CMOS RTC RAM data. After clearing the CMOS,
reinstall the battery.

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

These jumpers allow you to wake up the computer from S1 mode (CPU
stopped, DRAM refreshed, system running in low power mode) using the
connected USB device. Set this jumper to pins 2-3 (+5VSB) to wake up the
computer from S3 and S4 modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).

• The USB device wake-up feature requires a power supply that can
provide 500mA 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.

4.2 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

SPI chip.

The rmware chip 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, reboot the system by doing any of the
following procedures:

• Restart using the OS standard shut-down procedure.

• Press

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.

<Ctrl>+<Alt>+<Del> simultaneously.

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to
force reset from a running operating system can cause damage to your data
or system. We recommend to always shut-down the system properly from the
operating system.

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 Setup Defaults item under the
Exit Menu. See section “4.8 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.
