Chapter 3: BIOS setup
4.1 Knowing BIOS
The new ASUS UEFI BIOS is an 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 recommend that you change the BIOS settings only with the help
of a trained service personnel.
4.2 BIOS setup program
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 4.9 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 3.2
Jumpers 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.
