Yep. That's how you got Windows XP installed in the first place. There
are lots of LiveCD distros for Linux. BartPE's CD is bootable. As
Sebastian already said, if you permit physical access to the host then
it can be compromised. Why do you think the server room at the company
remains locked?

Since the BIOS runs first, no "overlap BIOS" program has yet run to
obviate the action of the BIOS - that of requiring the system password.
Booting from any device happens after the BIOS has already asked for the
system password. BIOSes on daughtercards run after the system BIOS so
they can't obviate the system BIOS, either.

Name the purported BIOS "overlap" device so we know you really know what
you claim to know.
