2.1.3Using AFUDOS to update the BIOS

The AFUDOS is a DOS-based application that lets you update the BIOS file using a bootable floppy diskette. AFUDOS also allows you to copy the original BIOS file to a floppy diskette.

To update the BIOS using the AFUDOS.EXE:

1.Visit the ASUS website (www.asus.com) to download the latest BIOS file for your motherboard. Save the BIOS file to a bootable floppy disk.

Write down the BIOS file name to a piece of paper. You need to type the exact BIOS file name at the prompt.

2.Copy the AFUDOS.EXE utility from the support CD to the bootable floppy disk that contains the BIOS file.

3.Boot the system from the floppy disk.4.At the DOS prompt, type the command line: afudos /i<filename.rom>

where “filename.rom” means the latest (or original) BIOS file that you copied to the bootable floppy disk.

The screen displays the status of the update process.

The BIOS information on the screen is for reference only. What you see on your screen may not be exactly the same as shown.
