I would guess the NuPower G3 driver but I don't know for sure. I also have a feeling that their drivers were combined all into the MaxPower product, but I could be wrong. It's just been too many years.

Oh, I have an 8100 with the upgrade in it. If I have it connected to a monitor again, I'll look at the system folder, but that's not likely to happen soon. It's hiding under a desk far from any display at the moment.
