IV. BIOS SOFTWARE
Support Software
NOTE: This motherboard has onboard SCSI and therefore requires a 2Mbit flash
ROM. This flash ROM requires PFLASH2.EXE as opposed to PFLASH.EXE as
used by other ASUS motherboards with 1Mbit flash ROM.
PFLASH2.EXE - This is the Flash Memory Writer utility that updates the BIOS by
uploading a new BIOS file to the 2Mbit programmable flash ROM chip on the moth-
erboard. To determine the BIOS version, check the last four numbers of the code
displayed on the upper left-hand corner of your screen during bootup. Larger num-
bers represent a newer BIOS file. This file works in DOS or Windows mode.
NOTE: The following screen contents in this user's manual are provided as ex-

Flash Memory Writer Utility
Main Menu
1. Save Current BIOS To File
This option allows you to save a copy of the original motherboard BIOS in case you
need to reinstall it. It is recommended that you save PFLASH2 and the BIOS file to
a bootable floppy diskette.
2. Update BIOS Main Block From File
This option updates the BIOS from a file on the disk. The file can be either a new
file or a backup file created by the “Save Current BIOS To File” option. If the boot
block in the file is different from the current boot block, this option will not update
the main block. Instead, it will display the following messages.
IMPORTANT! If “unknown” is displayed after Flash Type -- , the memory chip
is either not programmable or is not supported with the PnP BIOS and therefore
cannot be programmed by the Flash Memory Writer utility.
