No, different 720kb disk
I realized what I was trying to do was impossible; I was trying to put the
a partition (and therefore, disklabel) on the second cylinder (skipping
a whole cylinder) so that I could fit a boot manager of sorts onto the
first cylinder. I don't think floppies work this way - it would have to
have a bona fide partition table so NetBSD could find the NetBSD partition
and therefore the disklabel.
I was able to put the boot loader into the place of the normal stage1/2
of the "a" partition though, so no big dealie.
I noticed one thing; "int 13h service 8" reports incorrect geometries for
3.5" 720kb disks... it says there are 18 sect/track when in fact there
are 9. This is on a 1990 and 1992 BIOS. I wonder if all of them do
this.
