Chapter 3 UEFI SETUP UTILITY
3.1 Introduction
ASRock Industrial UEFI (Unified Extensible Firmware Interface) is a BIOS utility which
offers tweak-friendly options in an advanced viewing interface.
The UEFI system works
with a USB mouse and offers users a faster, sleeker experience.
This BIOS utility can perform the Power-On Self-Test (POST) during system startup, re-
cord hardware parameters of the system, load operating system, and so on. The battery on
the motherboard supplies the power needed to the CMOS when the system power is turned
off, and the values configured in the UEFI utility are kept in the CMOS.
Please note that inadequate BIOS settings may cause system instability, mulfunction or
boot failure. We strongly recommend that you do not alter the UEFI default configurations
or change the settings only with the assistance of a trained service person.
If the system becomes unstable or fails to boot after you
change the setting,
try to clear
the CMOS values and reset the board to default values.
See your motherboard manual for
instructions.
3.1.1 Entering BIOS Setup
You may run the UEFI SETUP UTILITY by pressing <F2> or <Delete> right after you
power on the computer; otherwise, the Power-On-Self-Test (POST) will continue with
its test routines. If you wish to enter the UEFI SETUP UTILITY after POST, restart the
system by pressing <Ctl> + <Alt> + <Delete>, or by pressing the reset button on the system
chassis. You may also restart by turning the system off and then back on.
This setup guide explains how to use the UEFI SETUP UTILITY to configure all the
supported system.
The screenshots in this manual are for reference only.
UEFI Settings and
options may vary owing to different BIOS release versions or CPU installed. Please refer to
the actual BIOS version of the motherboard you purchased for detailed screens, settings
and options.
