A non-pnp rom can't register a BCV, but it can hook int13 (or hook
int19 or do a direct boot).  Right now, if a user selects a "legacy
option rom" from the boot menu, SeaBIOS will still prioritize HD
booting even if the rom doesn't hook int13.  It's an open question
whether that is the right thing to do.  In practice, though, there
aren't many legacy option roms, so it's probably not a big deal.  The
"vapic.bin" should probably be upgraded to use a PNP header just so it
doesn't show up in the boot menu.
