I repeated the setup attempt on another machine with different hardware
and got stuck with the same problem. Does anybody have a idea regarding
the obvious that I could be missing in order to get these systems to
boot? Otherwise I'll get someone to sit in front of the machine and
look at the screen during a boot attempt :-)
