2.2 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.
• Refer to section Rear I/O connection for the location of the USB port that supports
BIOS FlashBack™.
2. Visit https://www.asus.com/support/ and download the latest BIOS version for this
motherboard.
3. Manually rename the le as WSXSG2.CAP, or launch the BIOSRenamer.exe
application to automatically rename the le, then copy it to your USB storage device.
The BIOSRenamer.exe application is zipped together with your BIOS le when you
download a BIOS le for a BIOS FlashBack™ compatible motherboard.
4. Shut down your computer.
5. Press the BIOS FlashBack™ button for three seconds until the FlashBack™ LED
blinks three times, indicating that the BIOS FlashBack™ function is enabled.
6. Wait until the light goes out, indicating that the BIOS updating process is completed.
