4. BIOS SETUP

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 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.

Updating BIOS

IMPORTANT! If “unknown” is displayed 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.
