lmsensors on Abit IC7-G

Hi,

On my Abit IC7-G there is a ICH5 chipset.  Once sensors-detect has been
updated with the 24d3 device id it generates a nice lm-sensors
configuration. Unfortunately there are no real temperature readings 
(there should be quite a few according to BIOS) or any fan-speeds (2 to 
4 should be right).  I also wonder about the corectness of the voltage 
readings.  In the BIOS display they are all 10% or less off nominal.

Is there anything I can test to see if I get more or more correct readings?

Wild guess: this isn't a LM80. No value here make sense. What you have
here is obviously another model of sensoring chipset.

Which version of lm_sensors are you using? Please try a recent version
of sensors-detect (preferably from CVS), it should be able to identify
the chip correctly.

If not, please send the output of "i2cdump 0 0x2e", we'll take a look
and try to identify the chip.

I just commited such a change to sensors-detect in CVS. Could you please
check it out and give it a try (after unloading all chip drivers, of
course)? If shouldn't detect a LM80 anymore.

You're wrong. You might not have ISA slots, still you *do* have an ISA
bus. Almost everybody does. And that's probably where your monitoring
chipset is hiding.

Here it is.

Error. You want to say yes. It will detect the W83627HF driver again,
and propose an alternate (and better) driver.

That said, the w83781d should have worked also, but W83627HF detection
is known to be broken in 2.8.1. I have fixed it since (2003-10-25) so if
you check lm_sensors2 CVS out, you should be able to use the w83781d
driver. But anyway, try Super I/O, it should give even better results.

Hm, did it really happen that way, or have you been cutting a part? (I
hope so.)

Exactly what I had expected.

Most chips don't monitor negative voltages anymore. I would bet that
your BIOS won't show these values either, so you can safely ignore them
(add "ignore" statements in your configuration file).

VCore 1/2 limits are wrong because of your bad vid reading (last line).
Try changing the vrm to 9.0 (uncomment one line in the configuration
file) and run "sensors -s", see if it helps. If it doesn't, set these
limits using real values instead of references to vid.

Fan values look OK, limits are way too low. Try changing divisors
(typical value is 2), it might help. Don't forget to run "sensors -s" as
root afterwards.

Temperatures look OK too, except the missing limits for temp1. Tweak
your config file to set the limits as you want them.

After that, you should have a fine-tuned hardware monitoring
configuration :)

OK.  Downloaded that and ran.  Assumptions:
- This is a pure PCI system, no ISA bus so no ISA probe, Intel ICH5 
chipset is correct.
- The ABIT mobo docs refers to this as a SMBus.

Here is the complete run:

# ./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.

  BIOS vendor (ACPI): IntelR
  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): y
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801EB ICH5
Probe succesfully concluded.

  We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
  Do you now want to be prompted for non-detectable adapters? (yes/NO): no
  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 already loaded.

  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: SMBus I801 adapter at 0500 (Non-I2C SMBus adapter)
Do you want to scan it? (YES/no/selectively): yes
Client found at address 0x08
Client at address 0x2e can not be probed - unload all client drivers first!
Client found at address 0x44
Client at address 0x50 can not be probed - unload all client drivers first!
Client at address 0x52 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.  Do you want to scan the ISA bus? (YES/no): no

  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.  Do you want to scan for Super I/O sensors? (YES/no): no

  Sorry, no chips were detected.
  Either your sensors are not supported, or they are
  connected to an I2C bus adapter that we do not support.
  See doc/FAQ, doc/lm_sensors-FAQ.html, or
  http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/lm_sensors-FAQ.html
  (FAQ #4.24.3) for further information.
  If you find out what chips are on your board, see

This suggests some more addresses on the bus to dump:

     Chip `Winbond W83627HF' (confidence: 8)


  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)? smbus

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
#----cut here----

To load everything that is needed, add this to some /etc/rc* file:

#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe w83781d
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----

Yes it is. I don't know what it is, but this is no LM80 for sure. We
would need to enhance our detection routine so that doesn't fall in that
kind of trap.

I'm curious. If you dump the chip again now, does it contain exactly the
same data or not?

According to MBM's site, the monitoring chip on your motherboard is a 
W83627HF. They also have that note: "select your board from the
installer to avoid problems". It could mean that there is some special
action to take before being able to access the chip.

Could you provide the full output of sensors-detect (CVS version if
possible)?
http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/prog/detect/sensors-detect

If it doesn't show that chipset, we'll have to ask Alex (MBM's author)
how he has been solving the problem.

Oh well O:-)

The CVS version worked better:

# 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.

  BIOS vendor (ACPI): IntelR
  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): yes
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801EB ICH5
Probe succesfully concluded.

  We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
  Do you now want to be prompted for non-detectable adapters? (yes/NO): no
  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 already loaded.

  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: SMBus I801 adapter at 0500 (Non-I2C SMBus adapter)
Do you want to scan it? (YES/no/selectively): yes

  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.  Do you want to scan the ISA bus? (YES/no): yes

  Now follows a summary of the probes I have just done.
  Just press ENTER to continue:

Driver `w83627hf' (should be inserted):
   Detects correctly:

This looks like real results.  The -12V is a bit worrying.  I'll compare
