• Do not disconnect the USB flash drive or power off the system during the BIOS
updating process. Doing so will interrupt the BIOS updating process. In case the
process is interrupted, follow the steps again to update the BIOS.
• If FLBK_LED flashes for five seconds and turns into a stable light, this indicates
that USB BIOS Flashback is not working properly due to an improper USB flash
drive connection, a BIOS file name error, or an incompatible BIOS file format. If this
happens, restart the syetem.
• Updating the BIOS poses some risks. If the BIOS program is damaged during the
updating process and the system fails to reboot, please contact your local ASUS
Service Center for assistance
For more BIOS update utilities in BIOS setup, refer to the section 3.11 Updating BIOS in
