* To use this package, you'll have to launch "sensors-detect" as root, and ask few questions.
  No need to modify startup files as shown at the end, all will be done.

* Special note for via686a and i2c-viapro : if you don t see the values, you probably have a PCI conflict.
  It will be corrected in next kernel. Change the /etc/sysconfig/lm_sensors to use i2c-isa + via686a
  (or i2c-viapro + another sensor)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. 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.
Do you want to probe now? (YES/no): yes
Probing for PCI bus adapters...
Sorry, no known PCI bus adapters found.

We will now try to load each adapter module in turn.
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.
Do you want to load `i2c-dev' now? (YES/no): yes
Module loaded successfully.

We are now going to do the I2C/SMBus adapter probings. Some chips may
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.

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no): yes
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM78-J' at 0x290...     No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No
Probing for `Silicon Integrated Systems SIS5595'...         No
Probing for `VIA VT82C686 Integrated Sensors'...            No
Probing for `VIA VT8231 Integrated Sensors'...              No
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): yes
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Fintek'...                       No
Trying family `ITE'...                                      Yes
Found `ITE IT8705F Super IO Sensors'                        Success!
    (address 0x290, driver `it87')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Fintek'...                       No
Trying family `ITE'...                                      Yes
Found `ITE IT8705F Super IO Sensors'                        Success!
    (address 0x290, driver `it87')

Some CPUs or memory controllers may also contain embedded sensors.
Do you want to scan for them? (YES/no): yes
AMD K8 thermal sensors...                                   No
AMD K10 thermal sensors...                                  No
Intel Core family thermal sensor...                         No
Intel AMB FB-DIMM thermal sensor...                         No

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

Driver `it87' (should be inserted):
  Detects correctly:
  * ISA bus, address 0x290
    Chip `ITE IT8705F Super IO Sensors' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue:

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

#----cut here----
# Chip drivers
modprobe it87
# sleep 2 # optional
/usr/bin/sensors -s # recommended
#----cut here----

If you have some drivers 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 the needed
modules are loaded.

Do you want to generate /etc/sysconfig/lm_sensors? (YES/no): yes

This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
   hwmon0/device is it87

Found the following PWM controls:
   hwmon0/device/pwm1
   hwmon0/device/pwm2
   hwmon0/device/pwm3

Found the following fan sensors:
   hwmon0/device/fan1_input     current speed: 4963 RPM
   hwmon0/device/fan2_input     current speed: 2136 RPM

Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!
Hit return to continue:

of your system by changing fanspeeds.
