UEFI BIOS Setup
Introduction
The purpose of this manual is to describe the sengs in the AMI UEFI BIOS Setup program on this
motherboard. The Setup program allows users to modify the basic system conguraon and save
these sengs to NVRAM.
UEFI 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 acvates at the rst stage of the boong process, loading and execung the
operang system. Some addional features, such as virus and password protecon or chipset
ne-tuning opons are also included in UEFI BIOS.
The rest of this manual will to guide you through the opons and sengs in UEFI BIOS Setup.
Plug and Play Support
This AMI UEFI BIOS supports the Plug and Play Version 1.0A specicaon.
EPA Green PC Support
This AMI UEFI BIOS supports Version 1.03 of the EPA Green PC specicaon.
ACPI Support
AMI ACPI UEFI BIOS support Version 1.0/2.0 of Advanced Conguraon and Power interface
specicaon (ACPI). It provides ASL code for power management and device conguraon
capabilies as dened in the ACPI specicaon, developed by Microso, Intel and Toshiba.
PCI Bus Support
This AMI UEFI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component Interconnect)
local bus specicaon.
Using Setup
When starng up the computer, press <Del> during the Power-On Self-Test (POST) to enter the
UEFI BIOS setup ulity.
In the UEFI BIOS setup ulity, you will see General Help descripon at the top right corner, and
this is providing a brief descripon of the selected item. Navigaon Keys for that parcular menu
are at the boom right corner, and you can use these keys to select item and change the sengs.
Note
»The default UEFI BIOS sengs apply for most condions to ensure opmum performance of the
motherboard. If the system becomes unstable aer changing any sengs, please load the default
sengs to ensure system’s compability and stability. Use Load Setup Default under the Exit Menu.
»For beer system performance, the UEFI BIOS rmware is being connuously updated. The UEFI BIOS
informaon described in this manual is for your reference only. The actual UEFI BIOS informaon and
sengs on board may be slightly dierent from this manual.
