3.10.5 USB BIOS Flashback
The USB BIOS Flashback allows users to update BIOS without entering BIOS or the
operating system by using a USB flash disk drive under standby power.
1. Download the latest BIOS program file from the ASUS website.
2. Extract and rename the BIOS image file to R4E.ROM.
3. Copy R4E.ROM to the root directory of the USB flash disk drive.
4. Turn off the system and connect the USB flash drive to the ROG Connect port (the
white USB 2.0 port) at the rear panel of the motherboard.
5. Hold the ROG Connect button until the
BIOS LED begins to blink, then release.
6. Wait until the LED stops to blink, then
the BIOS flash is completed.
• This function can only support devices such as a USB flash disk with FAT32/16 format
and single partition.
• DO NOT unplug the power of the system while updating the BIOS to prevent system
boot failure!
