4.1.4 AFUDOS utility

The AFUDOS utility allows you to update the BIOS le in DOS environment using

a bootable oppy disk with the updated BIOS le. This utility also allows you to

copy the current BIOS le that you can use as backup when the BIOS fails or gets

corrupted during the updating process.

Copying the current BIOS

To copy the current BIOS le using the AFUDOS utility:

• Make sure that the oppy disk is not write-protected and has at least

1024KB free space to save the le.

• The succeeding BIOS screens are for reference only. The actual BIOS

screen displays may not be the same as shown.

1. Copy the AFUDOS utility (afudos.exe) from the motherboard support DVD to

the bootable oppy disk you created earlier.

2. Boot the system in DOS mode, then at the prompt type:

afudos /o[lename]

where the [lename] is any user-assigned lename not more than eight

alphanumeric characters for the main lename and three alphanumeric

characters for the extension name.

A:\>afudos /oOLDBIOS1.rom

Main lename Extension name

3. Press

<Enter>. The utility copies the current BIOS le to the oppy disk.

4.1.5 ASUS CrashFree BIOS 3 utility

The ASUS CrashFree BIOS 3 is an auto recovery tool that allows you to restore

the BIOS le when it fails or gets corrupted during the updating process. You can

update a corrupted BIOS le using the motherboard support DVD, a oppy disk or

a USB ash disk that contains the updated BIOS le.

• Prepare the motherboard support DVD, the oppy disk or the USB ash

disk containing the updated motherboard BIOS before using this utility.

• For the P5QLD PRO motherboard, this utility will not function when you use

a PATA optical drive.

• Always connect the SATA cable to the SATA1 / SATA 2 connector;

otherwise, the utility will not function.

Recovering the BIOS from a oppy disk

To recover the BIOS from a oppy disk:

1. Turn on the system.

2. Insert the oppy disk with the original or updated BIOS le to the oppy disk

drive.

3. The utility displays the following message and automatically checks the

oppy disk for the original or updated BIOS le.

Bad BIOS checksum. Starting BIOS recovery...

Checking for oppy...

When found, the utility reads the BIOS le and starts ashing the corrupted

BIOS le.

Bad BIOS checksum. Starting BIOS recovery...

Checking for oppy...

Floppy found!

Reading le “P5QLDPRO.ROM”. Completed.

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, reboot the system by doing any of the

following procedures:

• Restart using the OS standard shut-down procedure.

• Press

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

• Press the reset button on the system chassis.

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

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 Setups Default 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.
