Flash Memory Writer Utility
AFLASH.EXE: This is the Flash Memory Writer utility that updates the BIOS by
uploading a new BIOS file to the programmable flash ROM chip on the motherboard.
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. This file works only in DOS mode.
NOTE: The following screen displays are provided as examples only and may not
reflect the screen contents displayed on your system.
Main Menu
1. Save Current BIOS To File
This option allows you to save a copy of the original motherboard BIOS in
case you need to reinstall it. It is recommended that you save AFLASH.EXE
and the BIOS file to a bootable floppy disk.
To save your current BIOS,
type [1] at the Main Menu
and then press <Enter>. The
Save Current BIOS To File
screen appears. Type a
filename and the path, for ex-
ample, A:\XXXXX-X and
then press <Enter>.
WARNING! 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.
