Knowing UEFI BIOS
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.
BIOS settings and options may vary due to different BIOS release versions. Please refer
to the latest BIOS version for settings and options.
Entering BIOS at startup

•
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 the <F5> hotkey.
•
If the system fails to boot after changing any BIOS setting, try to clear the CMOS and
reset the motherboard to the default value.
