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 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
AMI ACPI UEFI BIOS support Version 1.0/2.0 of Advanced Configuration
and Power interface specification (ACPI). It provides ASL code for power
management and device configuration capabilities as defined in the ACPI
specification, developed by Microsoft, Intel and Toshiba.
PCI Bus Support
This AMI UEFI BIOS also supports Version 2.3 of the Intel PCI (Peripheral
Component Interconnect) local bus specification.

menu are at the bottom right corner,
and you can use these keys to select
item and change the settings.
Notice
The def ault 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
