Subject: Bring in the trivial differences between this code and John Hay's new
 code.  Added a copyright for the work I did to this file a couple of years
 ago.  Add John's copyright too, since I'm sure I'll be pulling more into this
 code.  This also implements a new -n option to not allow breaking into the
 boot sequence which was original in the patch John posted (not in the
 original i386 code I based this boot2.c on, only the name is the same).  I
 haven't checked to see if he did that, or if it was one of Sam's
 improvements.
