I know that Linux supports these, but the floppy is FAT12 and early
hd-style or sd-style devices would likely be FAT16, both of which are
handled by the msdos fs module.  There is another module for FAT32,
called vfat.  Perhaps the msdos fs support in NetBSD only handles FAT12?
I don't know, I'm not really good with BSD yet, and I'm a terrible
programmer. :-)

Oddly, with MSDOS formatted floppies, you get a partition table that
looks
like:

3 partitions:
#        size   offset     fstype   [fsize bsize cpg/sgs]
  c:     1440        0     4.2BSD        0     0     0   # (Cyl.  0 -
79)


and you can instantly mout it with:

# mount -t msdos /dev/fd0a /mnt

...although /dev/fd0c doesn't work.

Backk to the zip, both:

fsck -T MSDOS: /dev/rsd1c and fsck -T MSDOS: /dev/rsd1a

Fail with:

Invalid signature in boot block: b9a4

Perhaps we're confusing the format DOS puts on diskettes with the FAT
file system on fixed media?
