	AH = xx (dynamically assigned based upon a search for a multiplex
		 number from C0h to FFh which doesn't answer installed)
	AL = 00h installation check
	ES:DI = 1492h:1992h
Return: AL = 00h not installed
	     01h not installed, not OK to install

Note:	this interface permits advanced communication with TSRs: it is possible
	  to make a generic uninstall utility, advanced TSR relocator programs
	  in order to fit fragmented memory areas, etc.
