Please see: http://www.lm-sensors.org/ticket/2182 The chip is indeed a National Semiconductor LM96000, but apparently no input connected. I have no idea why Dell did this. There's nothing we can do without additional technical documentation from Dell. > Also I have tried to monitor PowerEdge 860 using OpenIPMI, but I get > extraneous output too, some params appears to be disabled: > > ====================================================================== > # ipmitool sdr elist | grep -i temp > Temp | 01h | ns | 3.1 | Disabled > Planar Temp | 04h | ok | 7.1 | 28 degrees C > Temp Interface | 53h | ns | 7.1 | Disabled > ====================================================================== Well, at least you get _one_ temperature, that's better than zero... -- Jean Delvare
