Managing and Updating Your Motherboard’s BIOS
Upon First Use of the Computer System
1. Create a bootable system floppy disk by typing [FORMAT A:/S] from the
DOS prompt without creating “AUTOEXEC.BAT” and “CONFIG.SYS” files.
2. Copy AFLASH.EXE to the just created boot disk.
3. Run AFLASH.EXE from this new disk and select option 1. Save Current
BIOS to File. See 1. Save Current BIOS To File on the previous page
for more details and the rest of the steps.
Updating BIOS Procedures (only when necessary)
1. Download an updated ASUS BIOS file from the Internet (WWW or FTP)
or a BBS (Bulletin Board Service) (see ASUS CONTACT INFORMATION
on page 3 for details) and save to the disk you created earlier.
2. Boot from the disk you created earlier.
3. At the “A:\” prompt, type AFLASH and then press <Enter>.
4. At the Main Menu, type 2 and then press <Enter>. See 2. Update BIOS
Including Boot Block and ESCD on the previous page for more details
and the rest of the steps.
WARNING! If you encounter problems while updating the new BIOS, DO
NOT turn off your system since this might prevent your system from boot-
ing up. Just repeat the process, and if the problem still persists, update
the original BIOS file you saved to disk above. If the Flash Memory Writer
utility was not able to successfully update a complete BIOS file, your sys-
tem may not be able to boot up. If this happens, your system will need
service.
