  AMI BIOS Setup Utility 
The  AMI  UEFI  BIOS  provides  users  with  a  built-in  setup  program  to  modify  basic  system 
configuration. All configured parameters are stored in a flash chip to save the setup information 
whenever the power is turned off. This chapter provides users with detailed description about 
how to set up basic system configuration through the AMI BIOS setup utility. 
4.1  Starting 
To enter the setup screens, follow the steps below: 
1.  Turn on the computer and press the <Del> key immediately. 
2.  After you press the <Del> key, the main BIOS setup menu displays. You can access the 
other setup screens from the main BIOS setup menu, such as the Advanced and Chipset 
menus. 
  Note:    If your computer can not boot after making and saving system changes with Setup, 
you can restore BIOS optimal defaults by setting JP14 (see section 2.3.9). 
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI 
and  your  system  manufacturer  have  carefully  set  up  these  defaults  that  provide  the  best 
performance and reliability. 
4.2  Navigation Keys 
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS 
setup utility hot keys can be used at any time during the setup navigation process. These keys 
include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on. 
  Note:    Some of the navigation keys differ from one screen to another.
