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 keyboard,
mouse, s erial ports and disk drives. BIOS ac tivates at the first stage of the booting
process, loading and executing the operating system. Some additional features, such
as virus and password protection or chipset 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.

Supported CPUs
This AMI UEF I BIOS s uppo rts the Intel CPU.
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 these keys to select
item and change the settings.
Notice
The default UEFI BIOS settings apply for most conditions to ensure optimum
performance of the motherboard. If the system b ecomes unstable after
changing any settings, please load the default settings to ensure system’s
compatibility and stability. Use Load Setup Default under the Exit Menu.
For better system performance, the UEFI BIOS firmware is being
continuously updated. The UEFI BIOS informatio n described in this manual
is for your reference only. The actual UEFI BIOS information and settings on
board may be slightly different from this manual.
The content of this manual is s ubject to be changed without notice. We will
not be responsible for any mistakes found in this us er’s manual and any
system damage that may be caused by wrong-settings.
