UEFI BIOS Setup
Introduction
The purpose ofthis manual is to describethe 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 acomputer 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 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
UEFI BIOS.
The rest of this manual will to guide you through the options and settings in UEFI
BIOS Setup.
Plugand Play Support
ThisAMI UEFI BIOSsupportsthe Plugand Play Version 1.0A specification.
EPA Green PC Support
ThisAMI UEFI BIOSsupports Version 1.03 of the EPA Green PCspecification.
ACPI Support
AMI ACPI UEFI 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 the ACPI
specification, developed by Microsoft, Intel and Toshiba.
PCI Bus Support
This AMI UEFI BIOS also supports Version 2.3 of the Intel PCI (Peripheral
Component Interconnect) local bus specification.
DRAM Support
DDR3 SDRAM (Double Data Rate III Synchronous DRAM) is supported.

Using Setup
When starting up the computer, 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 change
the settings.
Notice
zThe default UEFI BIOS settings apply for most conditions to ensure optimum
perform ance 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 underthe Exit Menu.
zFor better system performance, the UEFI BIOS firmware is being continuously
updated. The UEFI BIOS information 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 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.

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 thekind ofbasic information CPUID can provide the operating system.
Options: Disabled (Default) / Enabled
Execute-Disable Bit

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.
Options: Enabled (Default) / Disabled
Adjacent Cache Line Prefetch
The processor has a hardware adjacent cache line prefet ch 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
