Support Software

FILELIST.TXT - View this file to see the files included in the support software.
PFLASH.EXE - This is the Flash Memory Writer utility that updates the BIOS by
uploading a new BIOS file to the programmable flash ROM chip on the mother-
board. 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.
NOTE: A binary BIOS file is no longer included with the support software. Save
the motherboard's BIOS file to a floppy disk as soon as your system is operational.
See "Flash Memory Writer Utility" in this section to "Save Current BIOS to File."

Flash Memory Writer Utility

The flash memory writer utility must be run while the system is in real mode. In
particular, the "Update BIOS Main Block From File" and "Update BIOS Including
Boot Block and ESCD" options require real mode. To run this utility, boot from a
system floppy disk without the AUTOEXEC.BAT and CONFIG.SYS files.
IMPORTANT: If "unknown" is displayed after Flash Type -- , the memory chip
is 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 copy the contents of the flash memory onto a floppy disk.
This gives you a backup copy of the original motherboard BIOS in case you need to
reinstall it. Create a bootable DOS diskette without AUTOEXEC.BAT and
CONFIG.SYS and save both PFLASH.EXE and the BIOS file(s) to it. Note: BIOS
FEATURES SETUP Boot Sequence needs to be set to A first in order to boot from
your disk drive A.
