The problem:
   MINIX refuses to boot from the distribution floppy.  The copyright
   message appears but the drive heads then get driven into the stops
   and back again.  An error message a reboot is attempted.  This
   repeats until I hit the reset switch & pull the floppy out.

Hypothesis:
   The Hyundai Super 386S is not as compatible with the IBM PC/AT as
   I thought.  The floppy controller presumably differs from the one
   bootblok expects.

Possible Solution 1:
   Make a copy of the generic (BIOS-based) boot floppy (#3) & apply a 
   binary patch to  the boot sector.  This should get me to the stage
   where I can patch bootblok.s and the floppy drivers & build a new
   boot floppy.  The obvious problem is that I don't know what the
   necessary patches out there are.  I don't even know what kind of
   controller the Hyundai is using.  Does anyone out there have any
   more information?

Possible Solution 2:
   Buy an add-in floppy controller (making sure that it has the right
   kind of chip).  The problem here is that I don't know if MINIX
   will boot off any floppy other than A:.  Does it?

Default Solution:
   Put MINIX back in the box, return it to Prentice-Hall & beg for
   my money back.

Can anybody think of something that I haven't (buying a new PC is not
a realistic option).
