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.
