To reprogram the System BIOS, you must first do the following:
1. Check the jumper J18 setting.
For "5V Flash EPROM", short pins 2 & 3 on J18.
For 12V Flash EPROM, short pins 1 & 2 on J18
The standard version of this mainboard uses a 12 volt flash
chip.
2. Make sure the CPU is running on the 'real mode'.
FMW will not run if the CPU is operating in a protected or
virtual mode. This means that you can not run it with Windows
running or with any memory manager software. You must
disable any memory manager software first. The easiest way to
do this is to:
a. Boot your system from a bootable floppy disk with no
CONFIG.SYS or AUTOEXEC.BAT files, and then run Flash
Memory Writer from a backup copy of your support disk. You
can make your back-up floppy bootable when you format it, and
use one disk for both purposes.
b. If you are using MS-DOS 6.x, you can use the feature that
allows you to confirm or abort each line of the CONFIG.SYS
file. You do this while pressing <F8> while the "Starting MS-
DOS..." line is on the screen.
There are other ways to accomplish the same result. The main
point is to make sure no memory managers are running. If you
are not sure, try running FMW. If it runs, then you have suc
ceeded. If it displays a warning message about the CPU
mode, you will have to try again.
