BIOS update utility
BIOS FlashBack™
BIOS FlashBack™ allows you to easily update the BIOS without entering the existing BIOS
or operating system. Simply insert a USB storage device to the USB port (the USB port
hole marked in green on the I/O shield) then press the BIOS FlashBack™ button for three
seconds to automatically update the BIOS.
To use BIOS FlashBack™:
1.
Insert a USB storage device to the BIOS FlashBack™ port.
We recommend you to use a USB 2.0 storage device to save the latest BIOS version for
better compatibility and stability.
2.
Visit https://www.asus.com/support/ and download the latest BIOS version for this
motherboard.
3.
Manually rename the file as M12A.CAP, or launch the BIOSRenamer.exe application
to automatically rename the file, then copy it to your USB storage device.
The BIOSRenamer.exe application is zipped together with your BIOS file when you
download a BIOS file for a BIOS FlashBack™ compatible motherboard.
4.
Shut down your computer.
5.
Press the BIOS FlashBack™ button for three seconds until the BIOS FlashBack™
LED blinks three times, indicating that the BIOS FlashBack™ function is enabled.

Do not unplug portable disk, power system, or press the CLR_CMOS button while
BIOS update is ongoing, otherwise update will be interrupted. In case of interruption,
please follow the steps again.
If the light flashes for five seconds and turns into a solid light, this means that the
BIOS FlashBack™ is not operating properly. This may be caused by improper
installation of the USB storage device and filename/file format error. If this scenario
happens, please restart the system to turn off the light.
Updating BIOS may have risks. If the BIOS program is damaged during the process
and results to the system's failure to boot up, please contact your local ASUS Service
Center.
