BIOS overview
The BIOS manages data flow between the computer's operating system and attached devices such as hard disk, video adapter, keyboard, mouse, and 
printer.
Boot menu
The Alienware Area-51 R2 includes a one-time boot menu. By using this feature,  you can change the sequence of devices that your computer attempts to boot  from, for example, CD-ROM, hard drive, or network.
Boot menu enhancements
The boot menu enhancements are as follows:
•Easier Access — Press F12 to access the boot selection menu.
•User Prompting — The user is prompted to use the keystroke on the 
BIOS screen.
•Diagnostics Options — The boot menu includes the ePSA diagnostic 
options.
Timing key sequences
The keyboard is not the first device initialized by Setup. As a result, if you press 
a keystroke too early, the keyboard is locked out. In such case, a keyboard error 
message is displayed on the screen, and you cannot restart your computer with 
the Ctrl+Alt+Del key combination.
To prevent the keyboard from locking, wait until the keyboard is initialized  completely. The keyboard is initialized if one of the following occurs:
•The keyboard lights flash.
•The F2=Setup prompt appears at the top-right corner of the screen during boot.

							System diagnostic lights
The computer POST (Power On Self Test) ensures that it meets the basic 
computer requirements and the hardware is working appropriately before the  boot process begins. If the computer passes the POST, the computer continues 
to start in a normal mode. However, if the computer fails the POST, the 
computer emits a series of LED codes during the start-up.
The following table shows different light patterns, what they indicate, and the 
suggested solutions.
