yes, it is sunix chip.
I've disabled native port, because I'm not 100% sure it works. It was an old motherboard with bent pins for parallel port output (and no pinout on motherboard), making it a bit difficult to verify.
I got the native parallel port to work. Bent and broken pins on MB were the source of my sorrow. In that regard the issue is resolved. However, on the other hand, I never got sunix card to work.
