Well, despite my continued (though slow) efforts, Minix still does not run
on my Unisys PW2 850 (Mitsubishi MP386).  I am running with 1.1 with two
patches: a) someone suggested adding a routine to print an asterisk and
calling it into the kernel initialization between where the interrupt
vectors for 0 - 15 are changed and where the ones for 16 - 255 are changed;
I also scattered calls to this print_star routine throughout main() and
set up things so INT 10H was not changed (so I could continue to print
asterisks up to the call to restart()).
b) the recent posted floppy.c (I believe from 1.4?) was added (modified to
remove the reference to ps).

When the machine is reset, it starts fsck just fine.  When I put in the
root file system disk and press "=", the calls to print an asterisk that
I scattered through main() display the asterisks up to the one just
before restart(), the floppy indicator light comes on, the screen blanks
and the world stops.

Does anyone have a clue where I should go from here?

Two things complicate my work: a) the technical reference that I ordered is 
on back order (last count there were 137 on back order) b) the machine that
Minix runs on (where I do my compiles and builds) is 15 miles from the
machine that I am trying to get Minix to run on.

ANY clues will be appreciated.
