UEFI BIOS Setup

Introduction

The purpose of 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 output d evices s uch as keyboard,

mouse, serial ports and disk drives. BIOS activates at the firs t stage of the booting

process, lo ading and executing the op erating s ystem. Some add itional features, s uch

as virus and pass word protection or chips et 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
