ASUS A7S333 motherboard
4.1 Managing and updating your BIOS
4.1.1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS
along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy
disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash
Memory Writer utility that updates the BIOS by uploading a new BIOS file to
the programmable flash ROM on the motherboard. This file works only in
DOS mode. To determine the BIOS version of your motherboard, check the
last four numbers of the code displayed on the upper left-hand corner of your
screen during bootup. Larger numbers represent a newer BIOS file.
1. Type FORMAT A:/S at the DOS prompt to create a bootable system disk.
DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk.
2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM
drive) to copy AFLASH.EXE to the boot disk you created.
NOTE! AFLASH works only in DOS mode. It does not work in the DOS
prompt within Windows, and does not work with certain memory drivers
that may be loaded when you boot from the hard drive. It is recommended
that you reboot using a floppy disk.
3. Reboot the computer from the floppy disk.
NOTE! BIOS setup must specify “Floppy” as the first item in the boot
sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
IMPORTANT! If the word “unknown” appears after Flash Memory:, the
memory chip is either not programmable or is not supported by the ACPI
BIOS and therefore, cannot be programmed by the Flash Memory Writer
utility.

5. Select 1. Save Current BIOS to File from the Main menu and press
<Enter>. The Save Current BIOS To File screen appears.
6. Type a filename and the path, for example, A:\XXX-XX.XXX, then
press <Enter>.

Chapter 4: BIOS Setup
4.1.2 Updating BIOS procedures
CAUTION! Update the BIOS only if you have problems with the
motherboard and you are sure that the new BIOS revision will solve your
problems. Careless updating may result to more problems with the
motherboard!
1. FTP) (see ASUS CONTACT INFORMATION on page x for details) and
save to the boot floppy disk you created earlier.
2. Boot from the floppy disk.
3. At the “A:\” prompt, type AFLASH and then press <Enter>.
4. At the Main Menu, type 2 then press <Enter>. The Update BIOS Including
Boot Block and ESCD screen appears.
5. Type the filename of your new BIOS and the path, for example, A:\XXX-
XX.XXX, then press <Enter>.
To cancel this operation, press <Enter>.
6. When prompted to confirm the BIOS update, press Y to start the
update.

7. The utility starts to program the new BIOS information into the Flash
ROM. The boot block is updated automatically only when necessary.
This minimizes the possibility of boot problems in case of update failures.
When the programming is done, the message “Flashed Successfully”
appears.
8. Follow the onscreen instructions to continue.
WARNING! If you encounter problems while updating the new BIOS,
DO NOT turn off the system because this may cause boot problems.
Just repeat the process, and if the problem persists, load the original
BIOS file you saved to the boot disk. If the Flash Memory Writer utility is
not able to successfully update a complete BIOS file, the system may not
boot. If this happens, call the ASUS service center for support.

Chapter 4: BIOS Setup
4.2 BIOS Setup program
This motherboard supports a programmable EEPROM 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 make changes to 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 EEPROM.
The EEPROM 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 among the predetermined choices.
NOTE! Because the BIOS software is constantly being updated, the
following BIOS setup screens and descriptions are for reference purposes
only, and may not exactly match what you see on your screen.
