yes, a typo in my e-mail only, I got the cmd right in the installer.

I'm left to assume that I have a modern system w/ a modern hard-drive (duh

I think it's fair to say, this is still causing some angst. :( I will check
out your link when my brain is far less foggy then it is right now. I'm a
bit woozy you could say, nyquil works fast on an empty stomach!

Indeed, I didn't, because I wasn't given a choice by sysinstall, it made the
choice for me.

Left Bruce in the CC, hopefully he'll offer some useful advice. :D *crosses

It would appear that the layout changes with each new major revision of
FBSD, I have different defaults on the old Sony VAIO on the floor next to me
that is running 7.3/i386.

No worries on missing it, I'm not sure that helped, I farted around with it
again earlier today with little more in the way of success. What I tried was
to just set up '/' and swamp and it still prompted me about not being able
to find /dev/ad4s1b. I will grab an 8.2B1 image tomorrow when I get up and
try that, see if it fairs better. Right now, I must sleep, this side of the
world is now just after 1am!
