BIOS Setup
1.1 Knowing BIOS
The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more exible 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 specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot device conguration 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 le, rename it as X99-E.CAP for this motherboard.

1.2 BIOS setup program

Use the BIOS Setup to update the BIOS or congure 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 rst 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 1.10 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 1.1.6 Onboard buttons and switches in your user manual for information on how to erase the RTC RAM via the
Clear CMOS button.
The BIOS setup program does not support the Bluetooth devices.
Please visit ASUS website for the detailed BIOS content manual.
