The whole basis of encryption assumes that the attacker has access to the message (your data), but that without the appropriate keys you can't usefully access it. No, this doesn't have much to do with the value or otherwise of BIOS passwords, but it's often stated that physical access renders all your data wide open, which isn't necessarily the case. Craig.
