I've managed to find an ARM710 to do the installation using
the voy4656 kernel. Worked fine once I realised (guessed?)
the 'Number of disk tracks (heads) per sector' means simply
how many heads are there, answer 16.
At least I think this is right, it seems to work!

All was fine until I tried to install the req sets, it seemed
to work, so I rebooted in native mode, and found that nothing
had installed.
No problem, I thought, just mount the cdrom, run 
/cdrom/usr/local/sbin/inst
and install the sets again. This didn't work, and now wd0a is
full (105%) and I have decided to stop before I do anything
more stupid.
Basically, I'd appreciate it if somebody could:
a) kick me,
b) explain how to free up some space and start again.

Is it possible to go right back to a clean RiscBSD partition
and start again?

Cheers.

PS. Sorry for sounding so thick, but I finished 2nd year exams
yesterday, and am in the process of moving house today, and I'm
knackered!
