5VSB computing on it87

Thank you Jean

So, this sensor is not assigned correctly, I could life with that for the moment, but my problem
is the alarm flag this sensors is causing, since the value for some reason is saturated.

I'd like to put this sensor on ignore for the moment, but I don't know how to do that:

*) ignore in7 - only prevents the sensor to be listed using the 'sensors' command
*) comment every line mentioning in7 in sensors3.conf - makes it appear under
/sys/devices/plattform/[...]/ anyway ! With the alarm flag in "in7_alarm" set to 1 - I need to get rid
of that...
*) trying to set in7 to value 0 (= unused): 'set in7_type  0' causes a parse error with 'sensors -s'
*) trying to raise the max_value barrier switching on the alarm: 'set in7_max    7 * 1.05'
this does not have an effect - the max limit stays at 6,.85, triggering the alarm!

What else can I try? I need the alarm flag in /sys/devices/plattform/[...]/in7_alarm to
be set to '0' - since I'm writing a small daemon who will parse for alarm values
only, starting a speaker beep when a alarm is discovered.

Thanks in advance for any help.
