Stay with me on this one. I've been watching an episode of Criminal Minds (1x01) and in it they demonstrate a piece of software (presumably made up) which sits beetween the BIOS and the OS and asks for a password; if the wrong password is entered X times, or a "hot password" (someone trying an obvious one you've left lying around) is entered, it flattens all the OS.

Is there anything like this around? Its more out of technical curiosity more than anything. Thres the obvious BIOS password stuff that can be subverted, and any OS level password is childs play; so this is quite interesting if possible.

Cheers all.
