BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the AMI BIOS Setup
program on this motherboard. The Setup program allows users to modify the basic
system configuration and save these settings to CMOS RAM. The power of CMOS
RAM is supplied by a battery so that it retains the Setup information when the power
is turned o f f.
Basic Input-Output System (BIOS) determines what a computer can do without
accessing programs from a disk. This system controls most of the input and output
devices s uch as keyboard, mous e, serial ports and dis k 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 BIOS.
The rest of this manual will to guide yo u through the options and s ettings in BIOS
Setup.

Using Setup
When starting up the computer, press
<Del> during the Power-On Self-Test
(POST) to enter the BIOS setup utility.
In the 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 c hange
the settings.
Notice
zThe default 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 s ettings to ensure system’s compatibility and stability. Use
Load Setup Default under the Exit Menu.
zFor better system p erformance, the BIOS firmware is b eing continuous ly updated.
The BIOS information described in this manual is for your reference only. The actual
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
responsib le for any mistakes found in this user’s manual and any system damage that
may b e caused by wro ng-s ettings.

Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its requirements
and prefetc hes data and ins tructio ns 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) / Dis abled
Adjacent Cache Line Prefetch
The processor has a hardware ad jacent 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 latency b y making the next cac he line
immediately available if the processor requires it as well.
Options: Enabled (Default) / Dis abled
Max CPUID Value Limit
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
Hyper Threading Technology
Enabled for Windows XP and Linux4 (OS optimized for Hyper Threading
Technology) and disabled for other OS (OS not optimized for Hyper Threading
Technology).
