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 information when 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 of the EPA Green PC specification.
APM Support
This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management
(APM) speci fication. Power management features are implemented via the System
Management Interrupt (SMI). Sleep and Suspend power management modes are
supported. Power to the hard disk drives and video monitors can also be managed by
this AMI BIOS.
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.

Interconnect) local bus specification.
DRAM Support
DDR3 SDRAM (Double Data Rate III Synchronous DRAM) is supported.
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 your referenceonly. 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
