2.1.4 AFUDOS utility
The AFUDOS utility allows you to update the BIOS le in DOS environment using a bootable
oppy disk. This utility also allows you to copy the current BIOS le that you can use as
backup when the BIOS fails or gets corrupted during the updating process.
• Ensure that you prepare two oppy disks: the bootable oppy disk and the oppy disk
containing the AFUDOS utility and the latest BIOS le.
• Ensure that the oppy disk is not write-protected and has at least 1072KB to save the
AFUDOS and BIOS les.
• The succeeding BIOS screens are for reference only. The actual BIOS screen displays
may not be the same as shown.
Updating the BIOS le
To update the BIOS le using the AFUDOS utility:
1. Insert the bootable oppy disk into the oppy disk drive to boot the system in DOS
mode.
2. Replace the bootable oppy disk and insert the oppy disk that contains the AFUDOS
utility and the latest BIOS le.
• Obtain the AFUDOS utility (afudos.exe) from the bundled support DVD and the latest
BIOS le from the ASUS website at www.asus.com.
• We recommend that you write the BIOS lename on a piece of paper. You will need to
key in the exact BIOS lename at the DOS prompt later.
3. At the DOS prompt, key in afudos /i[lename]
where [lename] is the BIOS le in the oppy disk.
Press <Enter>.
Do not shut down or reset the system while updating the BIOS to prevent system boot
failure!
4. The utility returns to the DOS prompt after the BIOS updating process is completed.
Reboot the system from the hard disk drive.
