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.
