Thanks for the reply. No, neither box is a compaq.
Actually, the problem was that I had extra memory
in box A (96M) and not in B (64M); I had altered
lilo to take this into account, but forgot about
it when I swapped boxes. When I upped the memory
in B to 96M the problem went away.
Thanks for your comment, though. I'll keep it
in mind for later.
