2.3.10USB BIOS Flashback

USB BIOS Flashback allows you to easily update the BIOS without entering the BIOS or operating system. Just connect the USB storage device containing the BIOS file to the USB port, press the BIOS Flashback button, and the BIOS is updated automatically.

1.Download the BIOS CAP file from the ASUS website at www.asus.com and save it to the root directory of your USB flash drive. Rename the CAP file to P9X79LE.CAP

2.Connect the USB flash drive to the bottom USB12 port at the rear panel.

3.Press the USB Flashback button for three seconds until the FLBK_LED flashes. The

FLBK_LED goes out when the BIOS update is completed.

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
