So, no, you can not assume that it is working at all. Maybe you could help us by letting us know what chip you actually have in your system. Running sensors-detect might give you a hint. Unfortunately the Nexcom datasheets don't say. In general, the voltages supported and measured by the SuperIO chip are regulated by circuitry on the board. Modifying the board input voltage doesn't necessarily mean that you see any change in a regulated voltage, and the SuperIO chip very likely reports only regulated voltages. You would have to get detailed technical information to know if it reports any unregulated voltages, or if there is some other chip on the board which reports those voltages. Most likely you would have to ask the board vendor to give you that information. Hope this helps, Guenter _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
