BIOS stands for "basic input/output
system." This software checks the health of your computer's hardware and
allows Windows to start. When you turn on your PC, its BIOS runs a
power-on self-test (POST) to ensure that the machine's devices (hard
drive, sound card, keyboard, and the like) are connected and working
properly. If the test finds no problems, the BIOS turns over control of
your PC to another piece of software, typically the operating system.
Every PC has a BIOS, and you may need to access yours from time to time. Inside the BIOS you can set a password, manage hardware, and change the boot sequence. The BIOS user interface is straightforward and easy to access, but you should take caution when exploring the BIOS--don't change settings if you don't know what they do.
2. Boot (or restart) the PC: Pay close attention to the first screen that appears. Look for a message that indicates which key you need to press in order to access the BIOS. That key is likely to be:
--A Function key (such as F1, F2, or F3)
--The Esc key
--The Delete key
