Is it possible to replace the bios while linux is running in normal
runlevels, assuming the bios has password protection on, and that the
attacker does not know the pass (nor does the attacker have physical
access)? It sounds more and more like bios virus protection and password
protection is something that the o/s must volunteer to go along
with...that the bios cannot stop its own overwrite, and merely asks
politely for a pass, but does not say "no" if the pass is bad.
