The new ASUS UEFI BIOS is an Unified Extensible Firmware Interface that complies with 

UEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-

only BIOS controls to enable more flexible and convenient mouse input. Users can easily 

navigate the new UEFI BIOS with the same smoothness as their operating system. The 

term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specified. 

BIOS (Basic Input and Output System) stores system hardware settings such as storage 

device configuration, overclocking settings, advanced power management, and boot device 

configuration that are needed for system startup in the motherboard CMOS. In normal 

circumstances, the default BIOS settings apply to most conditions to ensure optimum 

performance. We recommend that you not change the default BIOS settings except in 

the following circumstances: 
•  An error message appears on the screen during the system bootup and requests you to 

run the BIOS Setup.

•  You have installed a new system component that requires further BIOS settings or 

update.

Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly 

personnel.

A BIOS setup program is provided for BIOS item modification. When you start up the 

computer, the system provides you with the opportunity to run this program. Press <Del> 

during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues 

with its test routines.
If you wish to enter Setup after POST, press <Ctrl> + <Alt> + <Delete>, or press the reset 

button on the system chassis to restart the system. You can also turn the system off and then 

turn it back on to restart the system. Do this last option only if the first two failed.

The BIOS setup screens shown in this section are for reference purposes only, and 

may not exactly match what you see on your screen.

• 

Ensure that a USB mouse is connected to your motherboard if you want to use the 

mouse to control the BIOS setup program.

• 

If the system becomes unstable after changing any BIOS setting, load the default 

settings to ensure system compatibility and stability. Select the Load Optimized 

Defaults item under the Exit menu. See section 3.9 Exit Menu for details.

• 

If the system fails to boot after changing any BIOS setting, try to clear the CMOS and 

reset the motherboard to the default value. See section 2.2.5 Jumper for information 

on how to erase the RTC RAM.

• 

The BIOS setup program does not support the bluetooth devices.

The BIOS setup program is designed to make it as easy to use as possible. Being a  

menu-driven program, it lets you scroll through the various submenus and select from the 

available options using a keyboard or a USB mouse.
The BIOS setup program can be used under two modes: EZ Mode and Advanced Mode. 

You can change modes from the Exit menu or from the Exit/Advanced Mode button in the 

EZ Mode/Advanced Mode screen.
