BIOS overview
The BIOS manages data flow between the computer's operating system and
attached devices such as the hard disk, video adapter, keyboard, mouse, and
printer.
Entering the BIOS setup program
1
Turn on or restart your computer.
2
Press F2 when the Dell logo is displayed on the screen to enter the BIOS
setup program.
You can change the user-definable settings in BIOS setup program.
Timing key sequences
The keyboard is not the first device initialized by the BIOS setup program. As a
result, if you press a keystroke too early, the keyboard is locked out. In such cases,
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.
