             INT 67,4E - Get/Set Page Map Context  (LIM EMS 3.2+)

       AH = 4Eh
       AL = 00  get page mapping context into array
                ES:DI = pointer to destination array
            01  set page mapping context from array
                DS:SI = pointer to context source array
            02  get and set page mapping registers at once
                ES:DI = pointer to destination array
                DS:SI = pointer to context source array
            03  get size of page mapping array
            04-31  reserved


       on return:
       AH = 00  success
          = error code (see EMS STATUS)
       AL = bytes in pagemapping array (when AL=3)
       ES:DI = pointer to array with mapping info (AL=00/02)

       - an error will occur if ES:DI points to a buffer that will
         cause a segment swap
       - designed for use by multitasking operating systems only
