4.1.3 Using AFUDOS to copy BIOS from PC
The AFUDOS.EXE utility can also be used to copy the current system
BIOS settings to a floppy or hard disk. The copy can be used as a backup
in case the system BIOS fails or gets corrupted.
1. At the DOS prompt, type the command line:
afudos /o<filename>
where “filename” can be any user provided filename of not more than
eight (8) alpha-numeric characters for the main filename and three (3)
alpha-numeric characters for the extension name.
Press the Enter key.
The BIOS information on the screen is for reference only. What you
see on your screen may not be exactly the same as shown.

Reading flash ..... 0x0008CC00 (9%)
2. The utility will copy the current system BIOS by default to the floppy
disk. Make sure that the floppy disk is not write-protected and have
enough space (at least 600KB) to store the file.

4.1.4 Using ASUS EZ Flash to update the BIOS
The ASUS EZ Flash feature allows you to easily update the BIOS without
having to go through the long process of booting from a diskette and using
a DOS-based utility. The EZ Flash is built-in the BIOS firmware so it is
accessible by simply pressing <Alt> + <F2> during the Power-On Self
Tests (POST).
To update the BIOS using ASUS EZ Flash:
1. Visit the ASUS website (www.asus.com) to download the latest BIOS
file for your motherboard and rename the downloaded file as
P4P800.ROM. Save the BIOS file to a floppy disk.
2. Reboot the system.
3. To launch EZ Flash, press <Alt> + <F2> during POST to display the
following.
User recovery requested. Starting BIOS recovery...
Checking for floppy...
• If there is no floppy disk found in the drive, the error message
“Floppy not found!” appears.
• If the correct BIOS file is not found in the floppy disk, the error
message “P4P800.ROM not found!” is displayed. Make sure to
rename the downloaded BIOS file as “P4P800.ROM”.
4. Insert the floppy disk that contains the BIOS file. If all the necessary
files are found in the floppy disk, EZ Flash performs the BIOS update
process and automatically reboots the system when done.
DO NOT shutdown or reset the system while updating the BIOS! Doing
so may cause system boot failure!
User recovery requested. Starting BIOS recovery...
Checking for floppy...
Floppy found!

4.1.5 Recovering the BIOS with CrashFree BIOS 2
The CrashFree BIOS 2 auto recovery tool allows you to restore BIOS from
the motherboard support CD, or from a floppy disk that contains the BIOS
file, in case the current BIOS on the motherboard fails or gets corrupted.
1. Prepare the support CD that came with the motherboard or a
floppy disk that contains the motherboard BIOS before
proceeding with the BIOS update process.
2. If you have saved a copy of the original motherboard BIOS to a
bootable floppy disk, you may also use this disk to restore the
BIOS. See section “4.1.1 Creating a bootable floppy disk.”
To recover the BIOS from a floppy disk:
1. Boot the system.
2. When a corrupted BIOS is detected, the following screen message
appears.
Bad BIOS checksum. Starting BIOS recovery...
Checking for floppy...
3. Insert a floppy disk that contains the original or the latest BIOS file for
this motherboard. If all the necessary files are found in the floppy disk,
the BIOS update process continues.
Make sure that the BIOS file in the floppy disk is renamed as
“P4P800.ROM”.
Bad BIOS checksum. Starting BIOS recovery...
Checking for floppy...
Floppy found!
Reading file “P4P800.rom”. Completed.
Start flashing...
DO NOT shutdown or reset the system while updating the BIOS! Doing
so may cause system boot failure!
4. When the BIOS update process is complete, reboot the system.

Chapter 4: BIOS Setup
4.2 BIOS Setup program
This motherboard supports a programmable firmware hub (FWH) 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,
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 may want to
change the configuration of your computer in the future. For example, you
may want to 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 firmware hub.
The firmware hub 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 <Delete> 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 first two failed.
The Setup program is designed to make it as easy to use as possible. It is
a menu-driven program, which means you can 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 “4.7 Exit Menu.”
The BIOS setup screens shown in this chapter 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 product
and BIOS information.
