Chapter 2: BIOS setup

BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) 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, 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

SPI chip.
The SPI 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

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 ++ simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on.

• 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 “2.8 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.

• Visit the ASUS website (www.asus.com) to download the latest BIOS file for

this motherboard.

Using the power button, reset button, or the

++.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.
