Int 2F Fn D000  - Lotus Cd/networker - Installation Check                  [N]

   AX = D000h

Return: AL = FFh if CD/Networker TSR is loaded
   BX = 4D44h ("MD") signature
   CX = Windows mode word (from INT 2F/AX=1600h) at time of TSR load
   DX = bitmap identifying all loaded CD/Networker TSRs.

Notes: INT 2F/AH=D0h is used by CD/Networker to communicate between a
     resident redirector TSR and a transient program that controls the
     TSR's CD-ROM drive emulation (volume attachments, caching, etc).
   At present there is only one CD/Networker TSR; the bitmap always = 4.
