BIOS Setup
1. Knowing BIOS
The new ASUS UEFI BIOS is a Unified Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboardonly BIOS controls to enable a more flexible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your 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
optimal performance. DO 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 BIOS settings may result to instability or boot failure. We strongly
recommend that you change the BIOS settings only with the help of a trained
service personnel.
• When downloading or updating the BIOS file for your motherboard, rename it as
XXXXX.CAP. The name of the CAP file varies depending on models. Refer to the
user manual that came with your motherboard for the name.
• The screenshots in this manual are for reference only, please refer to the latest BIOS
version for settings and options.
• BIOS settings and options may vary due to different BIOS release versions or CPU
installed. Please refer to the latest BIOS version for settings and options.

2. BIOS setup program
Use the BIOS Setup to update the BIOS or configure its parameters. The BIOS screen
include navigation keys and brief onscreen help to guide you in using the BIOS Setup
program.
Entering BIOS at startup
To enter BIOS Setup at startup, press <Delete> or <F2> during the Power-On Self Test
(POST). If you do not press <Delete> or <F2>, POST continues with its routines.
Entering BIOS Setup after POST
To enter BIOS Setup after POST:
• Press <Ctrl>+<Alt>+<Delete> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on. Do this option only if you
failed to enter BIOS Setup using the first two options.
After doing either of the three options, press <Delete> key to enter BIOS.
• 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 or press hotkey <F5>. See section 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 your motherboard manual for
information on how to erase the RTC RAM.
• The BIOS setup program does not support Bluetooth devices.
BIOS menu screen
The BIOS Setup program can be used under two modes: EZ Mode and Advanced Mode.
You can change modes from Setup Mode in Boot menu or by pressing the <F7> hotkey.
The BIOS settings and options for each motherboard may differ slightly with the options in
this manual. Please refer to the BIOS of your motherboard for the settings and options.

Status definition:
• Frozen. The frozen state is the result of a BIOS protective measure. The BIOS
guards drives that do not have password protection by freezing them prior to booting.
If the drive is frozen, a power off or hard reset of your PC must be performed to
proceed with the Secure Erase.
• Locked. SSDs might be locked if the Secure Erase process is either incomplete
or was stopped. This may be due to a third party software that uses a different
password defined by ASUS. You have to unlock the SSD in the software before
