Int 2F/AX=1100h/SF=DADAh

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
