Actually, I used the instructions on the Bbench page, so I think they are pretty straightforward. However, the disk image there doesn't seem to work. I get the "dev/tty1: no such file or directory error" error. With the disk image I use at the moment, which I copied before the page was updated a few months ago, I get "can't access tty: job control turned off", but it seems to work better.
