Chapter 4 Bios; Introduction - Supermicro X11SCA User Manual

4.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the X11SCA/-W/-F motherboard. The
BIOS is stored on a chip and can be easily upgraded using a flash program.
Note: Due to periodic changes to the BIOS, some settings may have been added
or deleted and might not yet be recorded in this manual. Please refer to the Manual
Download area of our website for any changes to the BIOS that may not be reflected
in this manual.
Starting the Setup Utility
To enter the BIOS Setup Utility, hit the <Delete> key while the system is booting up. (In
most cases, the <Delete> key is used to invoke the 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 screen has three main frames. The upper frame displays the time and date,
as well as motherboard information (model, BIOS data, CPU data, and memory data). The
left frame displays all the features that can be configured. "Grayed-out" features cannot be
configured. 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 blue. Often
a text message will accompany it. (Note that BIOS has default text messages built in. We
retain the option to include, omit, or change any of these text messages.) Settings printed in
Bold are the default values.
A " " indicates a submenu. Highlighting such an item and pressing the <Enter> key will

open the list of settings within that submenu.
The BIOS setup utility uses a key-based navigation system called hot keys. Most of these
hot keys (<F1>, <F2>, <F3>, <Enter>, <ESC>, <Arrow> keys, etc.) can be used at any time
during the setup navigation process.
