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 motherboard. 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 numbers 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 examples only and may not reflect the screen contents displayed on your system. Flash Memory Writer Utility IV. BIOS Flash Memory Writer 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. 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. 30 ASUS P2L97A User's Manual
