Updating the BIOS
If the word “unknown” appears after Flash Memory:, the memory chip is either
not programmable or is not supported by the ACPI BIOS and therefore, cannot
be programmed by the Flash Memory Writer utility.
Update the BIOS only if you have problems with the motherboard and you are
sure that the new BIOS revision will solve your problems. Careless updating
may result to more problems with the motherboard!
1. Download an updated ASUS BIOS file from the Internet (WWW or FTP) (see
ASUS CONTACT INFORMATION on page viii for details) and save to the boot
floppy disk you created earlier.
2. Boot from the floppy disk.
