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 firs t stage of the booting
process, load ing and executing the operating s ystem. Some additional features, s uch
as virus and password protectio n or chips et fine-tuning optio ns are also inc luded in
UEFI BIOS.
The rest of this manual will to guide you through the options and settings in UEFI
BIOS Setup.

Using Setup
When starting up the co mputer, 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 selec ted 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 settings, 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 informatio n described in this manual is for yo ur 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 fo r any mistakes fo und in this user’s manual and any system damage that
may b e caused by wrong-settings.

Hyper-threading
Hyper Threading Technology can improve performance b y splitting instructions into
multiple streams. This item is enabled for Windows XP and Linux (OS optimized for
Hyper-Threading Technology) and disabled for other OS (OS not optimized for

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
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 c ache 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 hard ware ad jac ent c ache line p refetch mechanis m that
automatically fetches an extra 64-byte cache line whenever the processor requests for
a 64-byte cache line. This reduces cac he latenc y b y making the next cache line
immediately available if the processor requires it as well.
Options: Enabled (Default) / Disabled
Intel Virtualization Tech
Virtualization Techno lo gy can virtually separate your system reso urc e into several
parts, thus enhance the performance when running virtual machines or multi
interface systems.
