The therm_adt746x driver is a macintosh-specific driver not written nor maintained by the lm-sensors group. I tried to look at the driver's code but I have to admit I have no idea what they are doing with the limits. I also don't know how the monitoring chip is wired on the board. You should ask the macintosh people about your problems. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
