Chapter 4 BIOS Setup Description
The following section describes the BIOS setup program. The BIOS setup program can be used to view and
change the BIOS settings for the module. Only experienced users should change the default BIOS settings.

Entering the BIOS Setup Program.

The BIOS setup program can be accessed by pressing the <DEL> key during POST.

Boot Selection Popup

The BIOS offers the possibility to access a Boot Selection Popup menu by pressing the <F11> key during
POST. If this option is used, a message will be displayed during POST stating that the “Boot Selection
Popup menu has been selected” and the menu itself will be displayed immediately after POST thereby
allowing the operator to choose the boot device to be used.

Manufacturer Default Settings

Pressing the <End> key repeatedly, immediately after power is initiated will result in the manufacturer
default settings being loaded for that boot sequence and only that boot sequence. This is helpful when a
previous BIOS setting is no longer desired. If you want to change the BIOS settings, or save the
manufacturer default settings, then you must enter the BIOS setup program and use the 'Save and Exit'
function. This feature is enabled by default.

Setup Menu and Navigation

The BIOS setup screen is composed of the menu bar and two main frames. The menu bar is shown below:
The left frame displays all the options that can be configured in the selected menu. Grayed-out options
cannot be configured. Only the blue options can be configured. When an option is selected, it is highlighted
in white.
The right frame displays the key legend. Above the key legend is an area reserved for text messages. These
text messages explain the options and the possible impacts when changing the selected option in the left
frame.
The setup program uses a key-based navigation system. Most of the keys can be used at any time while in
setup. The table below explains the supported keys:
NOTE Entries in the option column that are displayed in bold print indicate BIOS default
values.
