4.1 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 floppy 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 just created boot disk.
NOTE: AFLASH works only in DOS mode. It will not work with DOS prompt in Windows and will not
work with certain memory drivers that may be loaded when you boot from your hard drive. It is
recommended that you reboot using a floppy.
3. Reboot your 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.
