7-1 Introduction
This chapter describes the AMI BIOS Setup Utility for the X8SIL/X8SIL-F. The AMI 
ROM BIOS is stored in a Flash EEPROM and can be easily updated. This chapter 
describes the basic navigation of the AMI BIOS Setup Utility setup screens.
Note: For instructions on BIOS recovery, please refer to the instruction 
guide posted at http://www.supermicro.com/support/manuals/.
Starting BIOS Setup Utility
To enter the AMI BIOS Setup Utility screens, press the <Delete> key while the 
system is booting up.
Note: In most cases, the <Delete> key is used to invoke the AMI BIOS 
setup screen. There are a few cases when other keys are used, such as 
<F1>, <F2>, etc.
Each main BIOS menu option is described in this manual. The Main BIOS setup 
menu screen has two main frames. The left frame displays all the options that can 
be confi gured. Grayed-out options cannot be confi gured. Options in blue can be 
confi gured by the user. The right frame displays the key legend. Above the key 
legend is an area reserved for a text message. When an option is selected in the 
left frame, it is highlighted in white. Often a text message will accompany it. (Note: 
the AMI BIOS has default text messages built in. Supermicro retains the option to 
include, omit, or change any of these text messages.)
The AMI BIOS Setup Utility uses a key-based navigation system called "hot keys". 
Most of the AMI BIOS setup utility "hot keys" can be used at any time during the 
setup navigation process. These keys include <F1>, <F10>, <Enter>, <ESC>, ar-
row keys, etc. 
Note: Options printed in Bold are default settings.
How To Change the Confi guration Data
The confi guration data that determines the system parameters may be changed by 
entering the AMI BIOS Setup utility. This Setup utility can be accessed by pressing 
<Del> at the appropriate time during system boot.
