 	- function request is specified in AL or AH
	- see  INT 2F,0  for installation checks
	- INT 2F uses AL to specify most documented functions but occasionally
	  uses AH also.  This can be quite confusing so INT 2F functions using
	  AH are not currently listed if the conflict but will be added at a
	  later time.
