MSCDEX (MS CD-ROM Extensions) - INSTALLATION CHECK

AX = 1100h subfn DADAh.

STACK:
WORD DADAh


Return:
AL = status
00h not installed, OK to install
STACK unchanged
01h not installed, not OK to install
STACK unchanged
FFh installed

STACK:
WORD     ADADh if MSCDEX installed
DADBh if Lotus CD/Networker installed

Note: Although MSCDEX sets the stack word to ADADh on return, any value other than DADAh is considered to mean that MSCDEX is already installed; Lotus CD/Networker v4+ uses this feature to fool MSCDEX into thinking it is already installed when it is in fact CD/Networker that is installed
