   And if I can get the 8086 to trap and ignore db'66' and   
   db'67' I will be able to have 16-bit executables that work   
   on either shift value.   
      
   And since I want the OS to return to real mode to do   
   BIOS calls, the 80386 is probably much better than the   
   80286 for this.   
      
   But I believe the 80286 can do it anyway, with sufficient   
   hardware support, and that would be a fun thing to do   
   as well.
