I don't know, but many BIOSes provide passwords. If the key management
I've seen elsewhere is any indication, the passwords probably are
stored as plaintext in a flash RAM, but, since recovering them (or
replacing the flash RAM) requires physical access to the machine, they
potentially provide some security. Of course, they may also have
backdoors, or even provide an official way to reset the password to a
known value.
