motherboard BIOS before using this utility.

Recovering the BIOS from the support DVD

To recover the BIOS from the support DVD:

1. Turn on the system.

2. Insert the motherboard support DVD to the optical drive.

4.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) 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, 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

LPC chip.

The LPC 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, 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 “4.9 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.

backup battery sustains the CMOS RAM so it stays on even when the PC is turned

off. When you select this option, a conrmation window appears. Select YES to

save changes and exit.

If you attempt to exit the Setup program without saving your changes, the

program prompts you with a message asking if you want to save your changes

before exiting. Press <Enter> to save the changes while exiting.

Exit & Discard Changes

Select this option only if you do not want to save the changes that you made to the

Setup program. If you made changes to elds other than System Date, System

Time, and Password, the BIOS asks for a conrmation before exiting.

Load Setup Default

This option allows you to load the default values for each of the parameters on the

Setup menus. When you select this option or if you press <F5>, a conrmation

window appears. Select YES to load default values. Select Exit & Save Changes

or make other changes before saving the values to the non-volatile RAM.

Discard Changes

This option allows you to discard the selections you made and restore the

previously saved values. After selecting this option, a conrmation appears. Select

YES to discard any changes and load the previously saved values.
