If this is a problem for you, I can write a custom stand-alone lm75 driver for your system in exchange of any item in my wish list below. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
