That's good information. Thanks. I did end up getting the console
working well enough on HP-UX to run sam and get the thing all cleaned
up. It's now on the network, hopefully I won't have to use the console
much in HP-UX, it's ugly.

I'm going to download some kernels and try netbooting them for the
heck of it. I also need to bring in another network card for the sparc
machine because I'm sure I'd get shut down if I started running
broadcast protocols on our network... I'll send you a dmesg if
possible.
