1. To set the video mode I want I've just been using
      movw $0x13, %ax
      int $0x10

   in an assemly language module. All the other examples
   I've seen use __dpmi_int or similar to call the
   interrupt. Is my code reliable?

2. The __djgpp_nearptr_enable functions appears to 
   return sucess but any attempt to access the
   video memory fails under NT. 
   Does anyone know why this is? farptr calls work
   fine.
