	AX = DE17h
	BX = function
	    0000h   get current mapping context without setting
	    nonzero set new mapping context to BX
Return: BX = mapping context in effect before call
Notes:	mapping contexts determine conventional-memory addressability; setting
	  a mapping context ensures that the associated program and data areas
	  are in memory for access.  Usable by drivers, TSRs and shared
	  programs.
	caller need not be running under DESQview
	this API call may be made from a hardware interrupt handler
