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.

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.

Limit CPUID Maximum
When the computer is booted up, the operating system executes the CPUID
instruction to identify the processor and its capabilities. Before it can do so, it
must first query the processor to find out the highest input value CPUID
recognizes. This determines the kind of basic information CPUID can provide
the operating system.
Options: Disabled (Default) / Enabled
Execute-Disable Bit
XD can prevent certain classes of malicious buffer overflow attacks when
combined with a supporting OS (Windows Server 2003 SP1, Windows XP
SP2, SuSE Linux 9.2, RedHat Enterprise 3 Update 3.).
Options: Enabled (Default) / Disabled
Intel Virtualization Technology
Virtualization Technology can virtually separate your system resource into
several parts, thus enhance the performance when running virtual machines
or multi interface systems.
Options: Disabled (Default) / Enabled
Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its
requirements and prefetches data and instructions from the memory into the
Level 2 cache that are likely to be required in the near future. This reduces
the latency associated with memory reads.
Options: Enabled (Default) / Disabled
Adjacent Cache Line Prefetch
The processor has a hardware adjacent cache line prefetch mechanism that
automatically fetches an extra 64-byte cache line whenever the processor
requests for a 64-byte cache line. This reduces cache latency by making the
next cache line immediately available if the processor requires it as well.
Options: Enabled (Default) / Disabled
