This chapter describes the AMI BIOS Setup Utility for the X8STi/X8STi-F/X8STi-3F/
X8STi-LN4. 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.
Starting BIOS Setup Utility

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

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".
