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 keybo ard,
mouse, serial ports and disk drives. BIOS activates at the first stage of the booting
process, load ing and executing the operating s ystem. Some add itional features, such
as virus and password pro tectio n 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.
