4.1 Managing and updating your BIOS

The following utilities allow you to manage and update the motherboard Basic

Input/Output System (BIOS) setup.

®

1.

ASUS Update (Updates the BIOS in Windows

environment.)

2.

ASUS EZ Flash 2 (Updates the BIOS using a oppy disk or USB ash disk.)

3.

ASUS AFUDOS (Updates the BIOS using a bootable oppy disk)

4.

ASUS CrashFree BIOS 3 (Updates the BIOS using a USB ash disk or the

motherboard support DVD when the BIOS le fails or gets corrupted.)

Refer to the corresponding sections for details on these utilities.

Save a copy of the original motherboard BIOS le to a bootable oppy disk or

USB ash disk in case you need to restore the BIOS in the future. Copy the

original motherboard BIOS using the ASUS Update or AFUDOS utilities.

4.1.1 ASUS Update utility

The ASUS Update is a utility that allows you to manage, save, and update the

®

motherboard BIOS in Windows

environment. The ASUS Update utility allows you

to:

• Save the current BIOS le

• Download the latest BIOS le from the Internet

• Update the BIOS from an updated BIOS le

• Update the BIOS directly from the Internet, and

• View the BIOS version information.

This utility is available in the support DVD that comes with the motherboard

package.

ASUS Update requires an Internet connection either through a network or an

Internet Service Provider (ISP).

Installing ASUS Update

To install ASUS Update:

1. Place the support DVD in the optical drive. The Drivers menu appears.

2. Click the Utilities tab, then click Install ASUS Update VX.XX.XX.

3. The ASUS Update utility is copied to your system.

ASUS P5E3 Premium/WiFi-AP @n 4-1

4.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) 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

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

<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 Setup Defaults 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.
