I had a mail exchange with Mark D. Studebaker, one of the developers of
lm_sensors.
The BP6 uses the winbond w83782d Hardware Monitoring IC and the module in
lm_sensors is for the w83781d chip . There are some differences
(if you are interested, go to the winbond site: http://www.winbond.com.tw
and get the tech notes) between the two chips. To be able to control
the pwm of fan2 on BP6 you have to add:
w83781d_write_value(client,W83781D_REG_PWMCLK12,0x19);
w83781d_write_value(client,W83781D_REG_BEEP_CONFIG, 0x85);
at the end of the w83781d_init_client() function in w83781d.c
(Thank you Mark!!!!)
The sensors.conf I use is:
Please note, I do not state that this file is correct, I think it is
correct, because it gives me reasonable values. If there are errors,
please write me.
