I bought a system with intel DG965RY motherboard year ago, and still no support for its
O/B sensors in linux.

Can I ask again, when you expect it to be released.
At least intel should release documents how to access the QST sensors.

I know that HECI is first step for that, but it is not enought to read those sensors.

I Really hope there are good news,
