UEFI BIOS Setup
Introduction
The purpose o f 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 outp ut devices such as keyboard,
mouse, s erial ports and disk drives. BIOS activates at the first stage of the booting
process, loading and executing the operating s ystem. Some additional features, s uch
as virus and pass word protectio n 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 UEF I BIOS s upports the P lug and Play Version 1.0A specification.

This AMI UEF I BIOS s upports the Intel CPU.
Using Setup
When starting up the co mp uter, 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 c hange
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 s ystem’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 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 b e c aused by wrong-s ettings.

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.

Adjacent Cache Line Prefetch
The processor has a hardware adjac ent cache line prefetch mechanis m that
automatically fetches an extra 64-byte cache line whenever the processor requests for
a 64-byte cac he line. This reduces cache latency b y making the next cac he line
immediately available if the processor requires it as well.
