The BIOS (basic input/output system) is a piece of firmware below the operating system. The BIOS is the firmware used to monitor and edit the CMOS (Complementary metal-oxide-semiconductor) settings. Depending on the make and model of the computer, the BIOS will have a different access key.

Step 1

Turn on your computer.

Step 2

Watch the bottom of the screen. There will be a message that says "Press a button to enter setup." On most systems capable of operating Windows XP Professional, the access key will be F1, F2, F10, DEL or ESC.

Step 3

Press the access key.

Step 4

Enter the password if one is set. By default, there will be no password.
