MMUPD.BAT Automatic EPROM Update
If the new code is supplied to you on a diskette or if you download the
new code from the Kingston BBS (which comes in the form of a self-
extracting executable file), there will be a file, MMUPD.BAT. This batch
file will run EPROM.EXE with the appropriate switches and load the
current HEX file automatically. Follow the EPROM instructions below,
but type MMUPD at Step 5 to run the ROM update automatically.
There might also be a new ADF file with the ROM update. If this is the case,
copy the new ADF file onto your PS/2 Reference diskette and your MCMaster
option diskette. Copy the new HEX file onto your option diskette. Run
EPROM.EXE this way:
1. Power up the system.
2. At the Kingston copyright notice, press the [o] key to return to the
original processor. EPROM.EXE WILL NOT OPERATE
PROPERLY IF EXECUTED BY THE MCMaster's ONBOARD
PROCESSOR.
3. Insert the backup copy of the option diskette into the floppy drive, log
on to the disk and run EPROM by typing:
4.
\>A: [Enter]
5. \>EPROM -f=mmxxx.hex [Enter]
6. After the program loads and executes, you will see this screen (or
something very similar):
