2.1.2 Using AFLASH to update the BIOS

Creating a bootable disk
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.
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.
BIOS setup must specify "Floppy" as the first item in the boot sequence.
