UEFI BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the AMI UEFI BIOS Setup
program on this motherboard. The Setup program allows users to modify the basic
system configuration and save these settings to NVRAM.
UEFI BIOS determines what a computer can do without accessing programs from a
disk. This system controls most of the input and output devices such as keybo ard,
mouse, serial ports and dis k drives. BIOS activates at the first stage of the booting
process, loading and executing the operating s ys tem. Some additional features, such
as virus and password pro tectio n or chips et fine-tuning options are also included in
UEFI BIOS.
The rest of this manual will to guide you through the options and settings in UEFI
BIOS Setup.

Using Setup
When starting up the computer, press
<Del> during the Power-On Self-Test
(POST) to enter the UEFI BIOS setup
utility.
In the UEFI BIOS setup utility, you will
see General Help description at the top
right corner, and this is providing a brief
description of the selected item.
Navigation Keys for that particular menu
are at the bottom right corner, and you can
use thes e keys to select item and change
the settings.
Notice
zThe default UEFI BIOS settings apply for most conditions to ens ure optimum
performance of the motherboard. If the system beco mes unstable after c hanging
any settings, please load the default settings to ensure system’s compatibility and
stability. Use Load Setup Default under the Exit Menu.
zFor better system performance, the UEFI BIOS firmware is being continuously
updated. The UEFI BIOS informatio n described in this manual is fo r your reference
only. The actual UEFI BIOS information and settings on board may be slightly
different from this manual.
zThe content of this manual is subject to be changed without notice. We will not be
responsible for any mistakes found in this user’s manual and any system damage that
may b e c aused by wrong-settings.
