Managing and Updating Your BIOS
4.1.1 Upon First Use of the Computer System
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.
