OK, but my point is that it might be interesting to see how far it
gets while booting on a 'unknown' system. The kernel could/should spit out
a nasty warning I suppose, but (maybe I'm dreaming) e.g. a 4100 might look
like a smaller 8200.

But are all machines completely different in this respect, or is there
some common ground? I have not studied this subject, mind you, but I'm
just curious.
