   Wow.   
      
   You think the entire MSDOS has been written   
   with no assumptions about 4 bit shifts?   
      
   You could be right. I've never looked at the   
   MSDOS source code except for one bit   
   someone pointed me to so that I could see   
   the word Xenix.   
      
   Ok, I guess we'll find out when I modify Bochs   
   or write my own emulator.
