Here's a note I saved a while back from Charles Hannum that explains how to
get this to work without having to repartition.  I haven't tried this myself,
but it makes sense to me.

(Personally I'd think it would be nice if the disk driver would punt and give
you a "d" partition of the whole disk if it didn't find a Unix partition, but
since that's not my case here it hasn't bothered me much).

Subject: Mounting an all-DOS disk in NetBSD

Assuming you don't have something (like OS-BS) which uses the extra
sectors in the boot track, you can do the following:

1) Use the NetBSD `fdisk' or DOS `pfdisk' to create a NetBSD partition
in the MBR which spans the entire disk.

2) Save a copy of the MBR:

        dd if=/dev/rsd0d of=my-mbr bs=1b count=1

3) Use `disklabel' to create a NetBSD label with the DOS partition and
whatnot.  Answer `y' when it asks you if you want to `overwrite [a]
disk with [a] DOS partition table'.

4) Put back the saved copy of the MBR:

        dd if=my-mbr of=/dev/rsd0d bs=1b count=1

This works for me.  Your milage may vary.
