Please note the following points about BIOS:
BIOS stands for Basic Input/Output System. The BIOS (sometimes called CMOS) is the program that controls a computer's boot process. The purpose of the BIOS is to identify and initialize processor, memory, hard drives, optical drives, video controller, audio controller and other hardware. The BIOS doesn't affect the Files on the computer or the Windows Operating System.
You can view all BIOS changes in the Release Notes included with the BIOS updates. If Release Notes are not included with the BIOS updates, please contact Asus Support.
If a BIOS update process is interrupted, your computer might not function properly. It is suggested the process be done in an environment with a steady power supply (preferably with UPS).
Please revert for clarification.
