1. Do not disconnect the USB flash drive or power system, or move the CLRTC jumper
during the BIOS updating process. Doing so will interrupt the BIOS updating process.
In case of interruption, follow the steps again to update the BIOS.
2. 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 improper USB flash drive
connection, BIOS file name error, or incompatible BIOS file format. If this happens,
restart the syetem.
3. BIOS updating 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
Chapter 3.
