   How do you know it's hung? You type character maybe?  Where does the
   character go - into DOS?  You are running a program, plus the clock
   is constantly interrupting etc.

   I cannot give you specific help with DrDOS but with MS DOS there is
   provision for something like 14 different A20 handlers to cater for
   various motherboard designs.  I have come across motherboards that
   need switches of the form /MACHINE:AT2 (to HIMEM) and that 'hang'
   without it.

   I suggest you explore this area of the DrDos documentation for
   possible options.
