Flash Memory Writer Utility
Your mamboard comes with a utility to upgrade the BIOS. The
BIOS is stored on a 'flash' EPROM BIOS ROM chip on the mainboard
that can be erased and reprogrammed. This is what the Flash Memory
Writer (FMW) utility does. The utility is in the "Flash" directory on
the DOS-formatted support floppy disk that comes with the
mainboard. You will find three files in the directory:
PFLASH.EXE
README
SS5IXXXX.AWD
- the Flash Memory Writer utility
- a text file of instructions
- a BIOS file for this mainboard
(xxxx = a 4-digit version number)
Flash Memory Writer records (or "programs") a new BIOS file
onto the flash memory chip. The BIOS file on the support disk may
be newer than the BIOS on the mainboard, so you may want to up­
date your BIOS right away. Compare the four numbers after "SS5I"
in the new BIOS file name to the last four numbers of the code that
displays in the upper left-hand comer of your screen while the Power-
On Self-Test is running. If the number from the support disk file is
larger, then you should reprogram the System BIOS. If they are the
same, don't bother. To reprogram the System BIOS, you must first do
the following:
1. Set jumper JP16 to the Boot Block Programmable setting. When
you finish updating the BIOS, set JP16 back to the default Boot
Block Protect setting. See Chapter 4 for jumper setting infor­
mation.
