     Obtain total number  of  logical expanded memory pages present in
     the system and the number of those pages not already allocated.

Note:   Upward and downward  compatible  with both EMS and EEMS 3.2.
        Note that EMS and EEMS 3.2 had no mechanism  to  return  the
        maximum number of handles that can be allocated by programs.
        This is handled by the EMS 4.0 new function 54h/02h.
