Hi Rik,

Not exactly my definition of the newbie, but nevermind ;)

FYI, this parameter is completely ignored by the w83627hf driver, both
for 2.4 and 2.6 kernels. Cleaning this up is part of my todo list...
among a dozen dozen other things, most of which have higher priorities
ATM.

Anyway you clearly don't need this, the w83627thf is always correctly
detected, and so is yours.

Which version of "libsensors" (and lm_sensors) is this? "sensors -v" and
"ls -l /usr/lib/libsensor* /usr/local/lib/libsensor*" should tell. I
think that the error on VID is caused by an old version of the library.
For a 2.6.8 kernel, I think I remember you need at least lm_sensor 2.8.6
(libsensors 3.0.4). If Suse backported some patches to their kernel, you
might even need 2.8.8 (libsensors 3.0.6).

I agree that the CPU temperature seems to be a bit low - however the MBM
site confirms that CPU temp is temp2 in diode mode for this motherboard,
so it would be correct. For motherboard you should set the sensor type
to thermistor, and hopefully you would get a decent reading. You can try
to switch temp3 to diode just in case, but most likely there's no third
sensor so you can just add "ignore temp3" to your configuration file.

If the motherboard BIOS displays some hardware monitoring information,
comparing with what "sensors" reports is usually a good way to get
things configured properly.

Hope that helps,
