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...
Use driver `i2c-i801' for device 0000:00:1f.3: Intel Enterprise
Southbridge - ESB2
We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
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.
Next adapter: SMBus I801 adapter at 1100 (i2c-0)
Do you want to scan it? (YES/no/selectively): YES
Client found at address 0x1f
Probing for `Maxim MAX6650/MAX6651'... No
Client found at address 0x2f
Probing for `National Semiconductor LM78'... No
Probing for `National Semiconductor LM78-J'... No
Probing for `National Semiconductor LM79'... No
Probing for `National Semiconductor LM80'... No
Probing for `Analog Devices ADT7470'... No
Probing for `Winbond W83781D'... No
Probing for `Winbond W83782D'... No
Probing for `Winbond W83792D'... No
Probing for `Winbond W83793R/G'... Success!
(confidence 8, driver `w83793')

Probing for `Winbond W83627DHG'... No

Probing for `Winbond W83791D'... No
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'... Yes
Found `Winbond W83627HF/F/HG/G Super IO Sensors' Success!
(address 0x295, driver `w83627hf')
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'... No
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... Success!
(driver `to-be-written')
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `w83793' (should be inserted):
Detects correctly:
* Bus `SMBus I801 adapter at 1100'
Busdriver `i2c-i801', I2C address 0x2f
Chip `Winbond W83793R/G' (confidence: 8)
Driver `w83627hf' (should be inserted):
Detects correctly:
* ISA bus, address 0x295
Chip `Winbond W83627HF/F/HG/G Super IO Sensors' (confidence: 9)
Driver `to-be-written' (should be inserted):
Detects correctly:
* Chip `Intel AMB FB-DIMM thermal sensor' (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----
# I2C adapter drivers
modprobe i2c-i801
# Chip drivers
# Warning: the required module w83793 is not currently installed
# on your system. For status of 2.6 kernel ports check
# http://www.lm-sensors.org/wiki/Devices. If driver is built
# into the kernel, or unavailable, comment out the following line.
modprobe w83793
modprobe w83627hf
# no driver for Intel AMB FB-DIMM thermal sensor yet
# 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 overwrite /etc/sysconfig/lm_sensors? (YES/no): YES
