Flashing the BIOS for Non-FAT file system  
4.Extract the file you have downloaded to a floppy (not the win ME/98 startup floppy) by double clocking the file in windows mode and supplying the path a:\
 
5.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.
If you do not have Windows ME or 98 to create the floppy you can make one on a friend's computer.
 
6.When boot is done there will be a message on the screen showing :"Diagnostic tools were successfully loaded to drive" followed by a single letter.
This letter is the leter assigned to the RAMDRIVE. This RAMDRIVE is a virtual drive in the system memory and can be accessed and controlled like any other drive with DOS commands such as:
MD - Make Directory
Copy - copy a file
Deleate - Deleate a file
 
There is one important difference which is that being in the system memory this drive is wiped once the computer is restarted or shut down.
 
7.Replace the startup floppy with the one containing the flash utility and bios ROM files previously extracted in windows.
 
8.Copy the 2 files to the RAMDRIVE by using the DOS command copy.
Here is an example, in this example the flash utility is AWFL814B.EXE ,the ROM file is  w6373nms.220  and the RAMDRIVE letter assignment is D
 
copy awfl814b.exe d:\
copy w6337nms.220 d:\
 
9.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:
 
10.Execute the flash utility with the ROM file as a command line argument, with this example:
awfl814b w6373nms.220
 
If you wish to save the current bios you must specify the full path a:\filename. Specifying only a file name will save the bios to the RAMDRIVE which will be wiped after restarting the computer and the file will not be saved.
 
a:\bios.old is an example of the correct way to save the bios.
 
11.Reboot your system when prompted
