**Flashing the BIOS for Non-FAT file system: ( Official MSI recommanded )

Boot the computer using a windows ME or windows 98 startup disk. It must be one of these! A plain boot disk will not be good enogh.
Replace the startup floppy with the one containing the flash utility and bios ROM files previously extracted in windows.
Copy the 2 files to the RAMDRIVE by using the DOS command copy.
Here is an example, in this example the flash utility is AWFLxxxx.EXE ,the ROM file is wxxxxnms.xxx and the RAMDRIVE letter assignment is D.

copy AWFLxxxx.EXE d:\
copy wxxxxnms.xxx d:\
(note: drive D and AWFLxxxx.EXE, wxxxxnms.xxx are just examples)

Change the current working directory to the RAMDRIVE root directory, with the example case of the RAMDRIVE being drive D this is done by simply done with the command d:

Execute the flash utility with the ROM file as a command line argument, with this example:
AWFLxxxx wxxxxnms.xxx
