Greetings,
I've just started to play with lm-sensors, and have almost got it working...
however, I'm getting some bogus values, and some others are missing:
- -12V is bogus
- Vbat looks bogus
- fan1 and fan2 both zero (even though 1 fan is installed and turning)
# sensors --version
sensors version 2.8.7 with libsensors version 2.8.7
My kernel is 2.6.11-gentoo-r8
My motherboard is an ASRock K7S41, and the sensor appears to be a S83627HF
The diagnostic stuff follows. Any help getting lm_sensors working with my
system would be very much appreciated (espeically as I'm a bit of a control
freak and want to monitor the health of my system).
TIA from Luxembourg,
David

# sensors-detect
This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.
It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.
We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-sis96x' for device 00:02.1: Silicon Integrated Systems SMBus
Controller
Probe succesfully concluded.
We will now try to load each adapter module in turn.
Load `i2c-sis96x' (say NO if built into your kernel)? (YES/no): no
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no): no
Well, you will know best. We will just hope you edited `/etc/modules.conf'
for automatic loading of this module. If not,
you won't be able to open any /dev/i2c-* file (unless youhave it built-in
into your kernel)
We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double
detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).
Next adapter: SiS96x SMBus adapter at 0x0c00 (Algorithm unavailable)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x08
Client found at address 0x10
Client at address 0x50 can not be probed - unload all client drivers first!
Client at address 0x51 can not be probed - unload all client drivers first!
Client found at address 0x69
Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.
Do you want to scan the ISA bus? (YES/no):

Trying address 0x0290... Failed!

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.
Do you want to scan for Super I/O sensors? (YES/no):

Failed! (skipping family)

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `w83781d' (may not be inserted):
Misdetects:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `Winbond W83697HF' (confidence: 8)
Driver `w83627hf' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `Winbond W83697HF Super IO Sensors' (confidence: 9)
I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)?
If you want to load the modules at startup, generate a config file
below and make sure lm_sensors gets started; e.g
$ rc-update add lm_sensors default.
To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----end cut here----
WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.
To load everything that is needed, execute the commands above...
#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe w83627hf
# sleep 2 # optional
/usr/bin/sensors -s # recommended
Do you want to generate /etc/conf.d/lm_sensors? Enter s to specify other
file name?
(YES/no/s):
Done.
# isadump 0x295 0x296
WARNING! Running this program can cause system crashes, data loss and
worse!
I will probe address register 0x0295 and data register 0x0296.
You have five seconds to reconsider and press CTRL-C!
