Managing and Updating Your Motherboard’s BIOS
Upon First Use of the Computer System
1. Create a bootable system floppy diskette by typing [FORMAT A:/S] from the
DOS prompt without creating “AUTOEXEC.BAT” and “CONFIG.SYS” files.
2. Copy PFLASH.EXE to your new diskette.
3. Run PFLASH.EXE from your new diskette and select option 1 “Save Current
BIOS to File.” Enter the “Current BIOS Revision:” for the file name.
Updating BIOS Procedures (only when necessary)
IMPORTANT: Flash type may be “SST” or “INTEL.” If “unknown” is displayed
after “Flash type --,” then this ROM chip is not programmable or not supported by
the PnP BIOS and therefore cannot be programmed by the Flash Memory Writer.
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. Turn off your computer and open the system cabinet to Boot Block Write Enable
the “Boot Block Programming” jumper as shown in section III.
3. Boot from the disk you created earlier.
4. At the “A:\” prompt, type PFLASH and then press <Enter>.
5. Enter 2 “Update BIOS Main Block From File” from the Main Menu or option 2
“Update BIOS Including Boot Block and ESCD” from the Advanced Features
Menu if prompted by option 2 of the Main Menu.
6. The program displays a second screen prompting you for the name of the BIOS
file. Type in the complete file name and extension of the new BIOS, and then
press <Enter>. The utility then updates the BIOS file from disk.
WARNING! If you encounter problems while updating the new BIOS, DO NOT
turn off your system since this might prevent your system from booting 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 system may not be able to boot
up. If this happens, your system will need service.
7. After successfully updating the new BIOS file, exit the Flash Memory Writer
utility and then turn off your system. Set the jumper back to its default setting of
Boot Block Write-Protect.
8. Turn on your computer and press <Delete> to enter BIOS setup. You must select
“Setup Default” to effect the new BIOS, then you may set other items from the
Main Menu.
