We do not recommend using the MSI LiveUpdate tool to update your BIOS! It may be okay for updating your drivers, but please do not use it to flash the BIOS in Windows! It is also not recommended to flash BIOS direct from a floppy disk, as a bad floppy can cause a bad flash which will kill your board!

Windows-based flashing - If you REALLY insist on flashing the BIOS under Windows, if you encounter any error during flashing, whatever you do, DON'T restart your PC! Try again until the flash is successful, otherwise your board will not start!

Boards with built-in M-Flash function - While this is a nice idea, at the moment we are seeing many cases of users using M-Flash to update their BIOS and having problems, so at present we don't recommend people use M-Flash either!

Before flashing your BIOS, you must ensure your system is fully stable! Please read >>> Are you a moron BIOS flasher? <<<

If you do not understand what your BIOS is, or what it does, please read: >> BIOS. What it is, and all you need to know <<

Our first choice we recommend you use is our own USB flashing tool, developed by our own Svet.

  >>>MSI Forum HQ USB Flashing Tool<<<

If you are unable to use the MSI HQ USB BIOS Flashing Tool

Please refer to the following PDF documents from MSI:

Modified and BETA BIOSes

Use only at your own risk! MSI will not provide any support if you use any modified ("modded") BIOS and you may invalidate your warranty. Please also be aware that MSI and this forum can not be held responsible if you trash your mobo by using a modded, beta or otherwise incorrect BIOS.

In many cases, provided the 'bootblock' of your BIOS is not corrupted during a bad flash, the BIOS can often be recovered by following the recovery procedures detailed below. NOTE: this recovery method should not be followed for normal practice of updating your BIOS! As you will be invariably forced to flash from a floppy disk, you'll need both a known good working floppy drive (non-USB) and a good floppy disk.

For Modern MSI Systems, refer to:

For older:

 For Award BIOS

Make a bootable floppy disk*
Copy the Award flash utility & BIOS file to the said floppy disk
Create an autoexec.bat with "Award_Flash_Utility BiosFilename" in the content (e.g. awdfl823K w6378vms.130)
Sample on how to create an autoexec:
a. On Windows, open the notepad
b. On the notepad, write "awdfl823K w6378vms.130" (without the " ")**
c. Save the file as autoexec.bat

Boot up system with the said floppy (it will take less than 2 minutes before screen comes out)

Re-flash the BIOS & reboot.

*Need a bootable floppy disk? Look here:
**Make sure you enter the correct filenames for your flasher program and BIOS ROM file!


Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM

Insert this floppy disk in the floppy drive. Turn On the system and press and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file and recover the BIOS from the A drive.

When 4 beeps are heard you may remove the floppy disk and restart the computer.

 For new boards with AMI BIOS core 8 (4MB)

Discovered by Jack The Newbie:

Of course, the steps are similar to the standard AMI BIOS Recovery Procedure for internal floppy drives (rename corresponding BIOS File to AMIBOOT.ROM, hit CTRL + HOME after starting the system).

What has to be done (tested on P45 Platinum):

1. An optical SATA Drive needs to be connected to one of the Intel ICH10R SATA ports. {After a lot of testing, I found that it does not work with the same optical drive connected to the SATA Ports hosted by the secondary JMicron Controller.  Also, using an optical drive on the JMicron IDE/PATA port does not help either.}

2. A proper BIOS File has to be renamed to AMIBOOT.ROM and burned on an empty CD.

3. CMOS-Clear with main A/C power cable removed from PSU has to be performed. {If this step is not done, the system will reboot after pressing CTRL + Home and will not proceed with recovery procedure.}
4. Press CTRL + Home to trigger BIOS Recovery.  -> The system should enter BIOS Recovery Routine. {Will basically work with both USB & PS/2 keyboard.  However, a PS/2 Keyboard is recommended as the system will respond earlier to PS/2 Keyboard than to USB Devices.}

What should happen now:

1. After pressing CTRL + HOME the LED Status should change to "Intializing Hard Disk Controller" and there should be access to the optical drive connected to the Intel ICH10R SATA ports.

2. It can take up to 30+ seconds until the BIOS File that was renamed to AMIBOOT.ROM is found. {Drive Bay can be opened to try a different CD without turning off or restarting the system.}

3. When the system finds the BIOS File, LED Status will change to "Testing RTC" and there should be a message on the screen indicating that the Flash Recovery Procedure has started.

4.  Since the BIOS File is 4MB in size, it will take a while until the BIOS is actually reflashed.

Its also possible that BIOS recovery on boards with AMIBIOS8 can be done using a FAT-formatted USB stick, containing the renamed BIOS file. Be warned, in some circumstances it may take several moments before recovery procedure actually begins. See Bas' reply below for further information.

BIOS recovery on Wind netbooks

See this post here:


Locate the BIOS chip on your mainboard. If it is soldered directly to the PCB like...

...then you have no choice but to return the board to your supplier, or to MSI, for replacement.
To request an RMA from MSI, open a support ticket at

If your BIOS chip is in a socket, like...

...then you may be able to source a replacement BIOS chip, either from MSI, or from a website such as

hi guys ,
i had an issue with my motherboard ("990FXA-GD80") after updating bios form 13.1 to 13.4 via GUI tool provided by msi after that my computer got frozen and when a rebooted , i was thinking that it was fried( black screen , and "F2" in debug LED)

 but with a littel help from MSI German forum especially from wiesel201 i was able to recover my motherboard  ;D

if anyone is having an issue after bios update (like "F2" in debug led ) all that you have to do is to put the previous bios ( the on that u had before the update in the / directory of a clean USB stick without changing the name , for me it was "E7640AMS.D10" ,plug the stick in USB 2.0 slot (rear panel) and power-on , after that you will see a bios screen telling you that had a corrupted bios and asking you to update it

i hope that i was helpful and greetings to Germany  :hat tip:
