Re: BIOS - What is it? How does it work? No clue on this..
With most motherboards it's the delete key, but some manufacturers change it to F12.
The BIOS is known as the Basic Input Output System - it looks at all your parts to check their working, then tells the hard drive to load up the Master Boot Record so that the OS can be loaded up. It's all automatic, but you can change some options like which component to load up first, such as CD-ROM drives or USB flash drives rather than the hard drive.
