OK, that makes sense. > (...) > I feel terribly bad I did not study the details on the web before asking > "basic" questions and wasting your time... thanks for your patience... No problem... The history of the project makes things confusing. I've made my best to clarify the situation but I know we're not there yet. > > You are not using lm-sensors for that.

If there is a way, it's specific to the scx200_acb driver and the underlying hardware. I am not familiar with this hardware myself, so I can't tell. -- Jean Delvare _______________________________________________ i2c mailing list [email protected] http://lists.lm-sensors.org/mailman/listinfo/i2c
