Reflash BIOS by USB Disk Under DOS Mode Procdure
Award BIOS Flash Procedure
1. Know your model number
a. Open your case and look for the MS-XXXX number on the motherboard between the PCI slots, also check the version number that is written there as well. (Some motherboards are named like K8N Diamond; make sure you have the right version number)
b. Boot up your system & take a look at the top left screen during POST, you should see something like “W7100NMS V1.1 021705” This means the board is MS-7100 with BIOS version 1.1
Hint: Many systems are clearing this message very fast, the bios version is then unreadable, and you can either press “PAUSE” or disable the “Quick Boot” in the BIOS setup.
2. Download the BIOS that matches your motherboard AND version number (some motherboards are named like K8N Diamond; make sure you have the right version number). BIOS can be found according to the CPU type of your board like if your CPU is AMD 939 type then look here
http://global.msi.com.tw/index.php?func=prodpage2&maincat_no=1&cat2_no=171
3. Extract the BIOS-archive that you have downloaded by double clicking to c:\test
4. Boot your system from a Win98 or WinME boot-floppy.
How to make boot floppy in case your don’t have it ready:
For Win9X, You can type [C:\ format a:/s] from the DOS prompt.
For WinME, You can make a boot floppy from control panel--> add/remove program-->make boot floppy. Remove autoexec.bat & config.sys file if there's any.
For Win2000, there's no way to make boot floppy, so you have to either use Win9X or WinME boot floppy.
For WinXP, you can make a DOS boot disk. Go to Your Computer, right click drive A:, select Format, select copy system files.
5. When you get the A:\ prompt, type the following sequence:
C: <enter>
cd\test <enter>
C:\test> awdfl865 BIOS file
(To save or not to save old BIOS is the user’s decision)
6. Reboot your system when prompted
AMI BIOS Flash Procedure
1. Know your model number
a. Open your case and look for the MS-XXXX number on the motherboard between the PCI slots, also check the version number that is written there as well. (some motherboards are named like P45 Diamond, make sure you have the right version number)
b. Boot up your system & take a look at the top left screen during POST, you should see something like “A7516IMS V1.4 082708” This means the board is MS-7516 with BIOS version 1.4
Hint: Many systems are clearing this message very fast, the bios version is then unreadable, and you can either press “PAUSE” or disable the “Quick Boot” in the BIOS setup.

C:\test> afud4234 BIOS file
(to save or not to save old BIOS is the user’s decision)
6. Reboot your system when prompted
Flashing the BIOS for Non-FAT file system
1. Know your model number
a. Open your case and look for the MS-XXXX number on the motherboard between the PCI slots, also check the version number that is written there as well. (Some motherboards are named like DKA790GX Platinum; make sure you have the right version number)
b. Boot up your system & take a look at the top left screen during POST, you should see something like “A7550AMS V1.2 090508” This means the board is MS-7550 with BIOS version 1.2
Hint: Many systems are clearing this message very fast, the bios version is then unreadable, and you can either press “PAUSE” or disable the “Quick Boot” in the BIOS setup.

2. Download the BIOS that matches your motherboard AND version number (some motherboards are named like DKA790GX Platinum; make sure you have the right version number). BIOS can be found according to the CPU type of your board like if your CPU is AMD AM2+ type then look here
http://global.msi.com.tw/index.php?func=prodpage2&maincat_no=1&cat2_no=171
3. 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:\
4. Boot the computer using windows ME or windows 98 startup disk. It must be one of these! A plain boot disk will not be good enough.
If you do not have Windows ME or 98 to create the floppy you can make one on a friend's computer.
5. 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 letter 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
Delete - Delete 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.
6. Replace the startup floppy with the one containing the flash utility and bios ROM files previously extracted in windows.
7. Copy the 2 files to the RAMDRIVE by using the DOS command copy.
Here is an example, in this example the flash utility is AFUD4234.EXE ,the ROM file is A7550AMS.120 and the RAMDRIVE letter assignment is D
copy AFUD4234.exe d:\
copy A7550AMS.120 d:\
8. 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:
9. Execute the flash utility with the ROM file as a command line argument, with this example:
afud4234 A7550AMS.120
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.
10. Reboot your system when prompted
12. If your system doesn't boot after you flashed, please refer to the BIOS recovery method as described
