Input		Output

BX			BX
CX			CX
DX	4456h ('DV')		DX
ES:DI	FAR Subroutine to be called on ???	DesqView Video Data Structures Seg	DS

Note:   This function is probably meant for internal use only, due to the
        magic value required in DX. The subroutine seems to be called when
        the DESQview menu is accessed; on entry, AL = 3 or 4
