Int 1A Fn B407  - Intel Plug-and-play Auto-configuration - ???             [X]

   AX = B407h
   EDX = length of ???
   EDI = physical address of ???

Return: CF clear if successful
       AX = 0000h
       EDX = ???
       EDI = ???
   CF set on error
       AX = error code (FFFFh) (see #0939)

Notes: returns error if EDI < 000C0000h or EDI+EDX > 00100000h
   seems to force EDI and EDX to align to 16K boundaries
