The patch checks for the presence of the Intel NM10, which, reading its description looks much like a south bridge and not a memory controller (north bridge). So I think the patch is wrong (or at least incomplete). Anyway, how difficult would it be to set TjMax based on the CPUID? I presume that the Intel Atom 400 and 500 series have their own CPUID value, haven't they? This would seem even easier that checking for a PCI device. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
