OK.  We'll keep that in mind.  I assume you don't want to make this new
disk bootable and thus make the whole disk for FreeBSD.

Actually, it somewhat does, you're on the right track.

You should use the following command(s) to generate a proper disklabel.

disklabel -Brw /dev/rwd2s1 auto
disklabel -e sd1

You should be dropped into vi.  Make a 'a' partition in the same format as
the 'c' partition; remember the numbers have to add up.  Save and quit,
and that'll become your disklabel.

You have to use the raw device /dev/rwd1.

I have a long message that describes the procedure in excruciating detail
(including fdisk) 
and another that is short for non-DOS-system 'dangerously dedicated'
disks.
