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.

Supported CPUs

This AMI UEF I BIOS s uppo rts the Intel CPU.

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

This item sets number of cores to enable in each processor package.

Options: All (Default) / 1 / 2 / 3

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.
