Creating a bootable disk
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.
To create a bootable floppy disk:
1. Insert a floppy disk to the floppy disk drive.
2. At the DOS prompt, type the command line:
FORMAT A:/S then press <Enter>.
Wait for a few minutes to complete format process.
3. Copy AFLASH.EXE to the boot disk you created.
To copy, type the command line:
COPY D:\AFLASH.EXE\AFLASH.EXE A:\ then press <Enter>.
