INT 2F - MS Windows WINOLDAP - SWITCHING ???

	AX = 4602h
Return: ???
Note:	the DOS 5+ kernel intercepts this function and copies the
	  previously-saved MCB from the DOS data segment into the MCB following
	  the caller's PSP memory block; in conjunction with AX=4601h, this
	  intercept is used by DOS to avoid corruption of the Windows real-mode
	  heap's end sentinel
