If you've got physical access to the machine, there's no way to
protect it. Even with a passworded BIOS, it is possible to reset the
CMOS with one of the jumpers on the motherboard.
The only protection would be to prevent bootup from any other physical
device, eg, by removing the floppy. Usually this isn't desirable.
Catch-22. You might try things like using compressed and/or encrypted
filesystems to prevent access from, eg, linux boot floppies, but it's
a lot of work (but possible) to set all that up.
Network security is another matter altogether... :)
