Because the way -kernel works is to create a fake bootsector internally, present it to the bios as the start of hda, and tell the bios to boot from that. If you haven't got an hda, it gets confused. (It probably shouldn't, since it's not actually _using_ it, but it does.)

Note that if you mmap /dev/zero it counts as an anonymous mapping, so feeding in /dev/zero for hda works just fine here.

Thank you, that works. And it's always good to know how it works.
