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 abattery so that it retains theSetup informationwhen the power

is turned off.

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 such as keyboard, mouse, serial ports and disk drives. BIOS activates at the

first stage ofthe 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 you through the options and settings in BIOS

Setup.

Plugand Play Support

ThisAMI BIOS supports thePlug and Play Version 1.0A specification.

EPA Green PC Support

ThisAMI BIOS supports Version 1.03 ofthe EPA Green PC specification.

ACPI Support

AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power

interface specification (ACPI). It provides ASL code for power management and

device configuration capabilities as defined in theACPI specification, developed by

Microsoft, Intel andToshiba.

H55A+ BIOS Manual

PCI Bus Support

This AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component

Interconnect) local bus specification.

Supported CPUs

ThisAMI BIOS supports the Intel CPU.

Using Setup

When starting up the computer, press

<Del> during the Power-On Self-Test

(POST) to enter theBIOS 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 these keys to select item and change

the settings.

Notice

zThe default BIOS settings applyfor 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 BIOS firmware is being continuously updated.

The BIOS information described in this manual isfor yourreferenceonly. The actual

BIOS information and settings on board may be slightly different from this manual.

zThe content ofthis 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.

C1E Support

C1E is “Enhanced Halt State” function, this function helps to save power and

decrease heat by lowering CPU frequency while the processor is not working.

Options: Enabled (Default) / Disabled

Hardware Prefetcher

The processor has a hardware prefetcher that automatically analyzes its requirements

and prefetches dat a 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 ifthe processor requires it as well.

Options: Enabled (Default) / Disabled

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 thekind ofbasic information CPUID can provide the operating system.

Options: Disabled (Default) / Enabled

Intel(R) Virtualization Tech

Virtualization Technology can virtually separate your system resource into several

parts, thus enhance the performance when running virtual machines or multi

interface systems.

Options: Enabled (Default) / Disabled

CPUTM Function

The CPU TM Function is to throttle the clock speed ofhigher speed Prescott's to

help keep them cool.

Options: Disabled (Default) / Enabled
