2-4 Chapter 2: BIOS Setup
5. To run AFLASH, at the DOS prompt type:
A:\AFLASH then press <Enter>
If the word “unknown” appears 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.
Updating the BIOS
6. Select 1. Save Current BIOS to File from the Main menu and press <Enter>.
The Save Current BIOS To File screen appears.
7. When asked to enter a filename to save, type a filename and the path. For
example, A:\XXX-XX.XXX , then press <Enter>.
Update the BIOS only if you are sure that the new BIOS revision will solve your
problems. Careless updating may result to more problems with the
motherboard!
• The AFLASH.EXE utility works only in DOS mode. It 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.
• DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk.
4. Reboot the computer from the floppy disk.
BIOS setup must specify “Floppy” as the first item in the boot sequence.
