INT 2F - QMR - INSTALLATION CHECK
        AX = C000h
Return: AL = FFh if installed
            ES:DI -> signature string "QMR1!"
Program: QMR (Cove Software, Quick Mouse Reset) monitors the mouse
          service interrupt (int 33h) and substitutes a fast software
          reset (mouse fn 21h) for the slow hardware reset (mouse fn 0).
Note:   QMR may use any multiplex number between C0h and FFh; it searches
         for itself in that range, and installs using the first free multiplex
         number in the range if not already loaded.
