4.1Managing 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 mother- board, 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 & 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.

IMPORTANT! If “unknown” is displayed after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and there- fore, cannot be programmed by the Flash Memory Writer utility.
