I did build a w83627ehf.ko driver for Ubuntu Natty system with the
ubuntu 2.6.38-8-generic kernel.
After some experiments I came to the following configuration file for
my ASRock E350M1 MB:
The used config file and the sensor output are at the bottom of this post.
The values of in4 - in7 I am quite sure about:
The values match almost exact the values of what I see in the bios reading.
The same is true for the temp1 and temp2, and for the fan speed.
The raw value of in8 is just below the value of in7, but that it is
reading the -12V is just a wild guess.
It's a very long time since I last saw a board monitoring -12V. I'm not
sure if it is still used at all.
in2 and in3 are always exactly 3.3 V, so I suppose those are Vcc
Yes, these are internally routed and scaled so always correct.
in0 and in1 fluctuate between 0.95 and 1.35 V where in0 rises first when
there is more processor activity.
I called them VCore 1 and 2, but not sure about those.
Strange, you have a single CPU so there should be a single Vcore value.
there is always a reading in the sensors that is labeled cpu0_vid, and
always has the value 0.0V, but I have no idea what this is telling, or
how I can remove it.
cpu0_vid is the voltage your CPU is requesting from the motherboard, if
the signal is properly routed to the monitoring chip. In your case it
doesn't work, either because the decoding for your CPU model isn't
known (you'd get a warning in the kernel log) or because the signal
isn't routed to the monitoring chip.
You can read more about VID pins at:
http://www.lm-sensors.org/browser/lm-sensors/trunk/doc/vid
(Not necessarily up-to-date, but still a good introduction.)
If you want to ignore cpu0_vid, just add:
ignore cpu0_vid
as for any other input.
Anyone can confirm or give comment on those settings?

Can't be. in7 and in8 are internally routed and scaled (just as in2 and
in3). In fact the default configuration for this chip reads:
label in2 "AVCC"
label in3 "+3.3V"
label in7 "3VSB"

So your configuration should start from there.

Most probably unused so you can use an "ignore" statement.

One of these is probably +12V. What does the BIOS show exactly? If some

scaling factors.
