3 BIOS CONFIGURATION
The SB5520DT1 motherboard uses the American Megatrends (AMI) BIOS with RadiSys
extensions. The AMI ROM BIOS is stored in a Flash EEPROM. Using the AMI BIOS setup utility,
you can easily display and modify the system configurations.
This chapter describes the basic navigation of the BIOS setup utility screens and each BIOS
item.
Starting the BIOS setup utility
To enter the BIOS setup utility, press the Delete key during system boot. The system BIOS setup
screens and menu options are the standard AMI BIOS screens with SB5520DT1 extensions.
Use the up, down, left, and right arrow keys on your keyboard to navigate through the menu
options.
Note: In most cases, the Delete key invokes the AMI BIOS setup utility. Other machines may
use a different key, such as F1 or F2.
After you have completed the BIOS settings, press F10 or use the commands on the Exit menu
to save changes. Press Esc to go immediately to the Exit menu.
W
ARNING! Do not upgrade the BIOS unless your system has a BIOS-related issue.
Flashing the wrong BIOS can cause irreparable damage to the system. In no event shall
RadiSys be liable for direct, indirect, special, incidental, or consequential damages arising
from a BIOS update. If you have to update the BIOS, do not shut down or reset the
system while the BIOS is updating. This is to avoid possible boot failure.
About the setup utility
The setup utility contains three main frames:
 Menu frame – Organizes related BIOS items into functional groups. Select a menu to
display and configure its related BIOS items.
 Left frame – Displays the BIOS items contained in the selected menu. Items that you can
configure appear as blue text, which changes to white when selected. Throughout this
chapter, options that appear in bold are default settings. Read-only items appear as gray text.
 Right frame – Displays the key legend, which describes the keys that you can use to
navigate the setup screens. Most of these keys can be used at any time. Above the key
legend is an area reserved for a text message that can accompany an item selected in the
left frame.
Note: The AMI BIOS has default text messages built in. RadiSys retains the option to
include, omit, or change any of these text messages.
