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, serial ports and disk drives. BIOS activates 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.
Plug and Play Support
This AMI UEFI BIOS supports the Plug and Play Version 1.0A specification.
EPA Green PC Support
This AMI UEFI BIOS supports Version 1.03 of the EPA Green PC
specification.
ACPI Support

Supported CPUs
This AMI UEFI BIOS supports 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 becomes
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 information 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 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 be caused by
wrong-settings.
