Can I bow at your feet?!? This gave me just enough of a clue to go back and
arbitraility pass 'gpart delete -i 1 ad4' which actually deleted a
partition! I then zeroed the first 73 and the last 33 blocks of the drive.
fdisk still complained about 'Class not found' which I googled and found to
be an artifact of gpart(8).

So my question is this now, once gpart has touched a disk, does it have the
partition-aids now?

Moving on, I then continued the standard process listed by your link,
bsdlabel'd my layout and saved it, when I do an 'ls -lsga /dev | grep ad4' I
see that I have partitions a,b,d,e,f and I was able to newfs each one of

Next question, from this point (at the fixit prompt) can I preform a manual
install of just base? if I can get the system installed at this point then
all should be good when I reboot.
