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 sys tem controls most of the input and output d evic es s uch as keyboard,
mouse, serial ports and dis k drives. BIOS activates at the first stage o f the booting
process, loading and executing the op erating s ys tem. Some add itional features, s uch
as virus and pass word protectio n or chips et fine-tuning op tions are also includ ed in
UEFI BIOS.
The rest of this manual will to guide you through the options and settings in 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 ensure optimum
performance of the motherboard. If the system becomes unstable after changing
any s ettings, 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 information describ ed 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 fo und in this user’s manual and any system damage that
may be caused by wrong-s ettings.

Limit CPUID Maximum
When the computer is booted up, the operating system executes the CPUID
instruction to identify the processor and its c apabilities. Before it can do so, it must
