It was probably done this way because for normal IDE drivers, "-boot c"
is a different boot path than "boot=on" - i.e. the former goes through
the normal BIOS boot path, but "boot=on" uses the extboot PCI option ROM
Probably could just use extboot for "-boot c" when the drive in question
isn't an IDE drive, though ...
