     Returns  the  number  of  unallocated   non-standard  length
     mappable pages as  well  as the total number of non-standard
     length mappable pages of expanded memory

     Notes:

     *  An  expanded  memory  page which is a sub-multiple of 16K is
        termed  a  raw  page.  An  operating  system  may deal  with
        mappable physical page sizes which are sub-multiples  of 16K
        bytes.

     *  If  the  expanded  memory  board  supplies  pages  in  exact
        multiples of 16K bytes,  the  number  of pages this function
        returns  is  identical  to  the  number   Function   3  (Get
        Unallocated Page Count)  returns.  In this case, there is no
        difference between a page and a raw page.
