Int 67 Fn 5DE9  - Rm386 - Set Partial Page Table                           [m]

   AX = 5DE9h
   BX = starting page number in first megabyte+HMA (0000h-010Fh)
   CX = number of page table entries to get
   DS:SI -> buffer of DWORD page table entries

Return: AH = status (00h successful, 8Bh invalid destination page)

Note:  RM386 traps this functions on the initial transition to protected
     mode caused by the INT instruction, which means it can not be
     overridden simply by hooking the interrupt
