2. Make sure the CPU is running in ‘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 before you can run
FMW. The easiest way to do this is as follows:
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 bypass the CONFIG.SYS and AUTOEXEC.BAT
file. You can access this feature by pressing <F5> while the
“Starting MS-DOS...” line is on the screen.
There are other ways to get FMW to run. The important thing
is to ensure that no memory managers are running. If you are
uncertain whether or not there is a memory manager running
on your system, try running FMW. If it works, then there is no
active memory manager. If you see a warning message about
the CPU mode, check to see that you have followed the
directions properly, and try again.
Once you have satisfied the two requirements mentioned above, you can
run FMW. You can copy the contents of the “Flash” directory to your
hard drive, or you can run the utility from a backup of the support floppy
disk. Either way, make sure that the new BIOS file is in the same direc-
tory as the FMW utility.
