   I know nothing of pmode. I've never coded anything in it directly.

   FreeDOS HIMEMX 3.32 had a bug where it wouldn't work on some old   
   386 laptops that two people still sometimes used (at the time).   
   IIRC, the unofficial fix (3.33, albeit without official maintainer)   
   was to add "jmp $+2". But it wasn't needed in newer cpus, apparently.   
      
   Is that what you meant?
