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 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.
