What about non pnp roms that also register bcv? Should we use HD > priority for those too? 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. -Kevin
