• 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.
