I don't know how much we can do about that.  "localboot 0" and
"localboot -1" are effectively different ways to request the same
service from the BIOS, but it seems one is broken.  Other than having a
huge quirks table, of course, but that is problematic in itself.

chain.c32 may be a better option all around... instead of exiting to the
BIOS to let it pick up the next device, it loads the boot data from disk
directly.
