I see from down below that it looks like you're running "disklabel fd0" ...
is that right? If so, I _think_ what's happening is that it's trying to use
/dev/rfd0d. The minor device numbers on the floppies are used to select
drive densities, so if you just say "fd0" you'll get the wrong device. What
happens when you try "disklabel /dev/rfd0a"? (I freely admit this is all
confusing :-) )

Well, it's supposed to be used to manipulate MS-DOS partition tables; if there
ain't a MS-DOS partition table on the disk (which is usually the case if you
install NetBSD on the whole drive) then it won't have much to do :-)

1048? I was under the impression you couldn't set the BIOS to more than 1023
cylinders? But I see from down below you tried a fake geometry, so obviously
that's not the problem.
