I think my first course of action would be to use DOS, or possibly OS/2, to
override the disk geometry, unless the disk has data on it that can only be
accessed from OpenBSD. Yes, I know it's intellectually more fun to get
OpenBSD to do it, but for a one off with little practical future use I
think
I'd use something else. DOS, OS/2 and OpenBSD can of course all be booted
from floppy, thus avoiding any early initialisation nastiness.
I'm not sure what you're describing here. Also, accessing the data from
DOS still leaves the problem of moving it. Or perhaps I didn't make it
sufficiently clear that the goal was to copy the data off the drive...
