# sensors-detect revision 5108 (2008-01-22 04:22:47 -0800)
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):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7
We will now try to load each adapter module in turn.
Load `i2c-i801' (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.
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 3000 (i2c-0)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x2e
Handled by driver `lm85' (already loaded), chip type `lm85'
Client found at address 0x44
Probing for `Maxim MAX6633/MAX6634/MAX6635'... No
Client found at address 0x50
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'... No
Client found at address 0x51
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'... No
Client found at address 0x52
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'... No
Client found at address 0x53
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'... No
Here it is. I'd notice that I used 2.6.23-gentoo-r3 kernel with builtin lm85
driver. If you need I can easily build any other kernel with any
drivers/etc.
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):
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):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... Yes
Found `SMSC SCH5027D-NW Super IO'
(hardware monitoring capabilities accessible via SMBus only)
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):
AMD K8 thermal sensors... No
AMD K10 thermal sensors... No
Intel Core family thermal sensor... Success!
(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `lm85' (should be inserted):
Detects correctly:
* Bus `SMBus I801 adapter at 3000'
Busdriver `i2c-i801', I2C address 0x2e
Chip `lm85' (confidence: 6)
Driver `coretemp' (should be inserted):
Detects correctly:
* Chip `Intel Core family thermal sensor' (confidence: 9)
Do you want to generate /etc/sysconfig/lm_sensors? (yes/NO):
To load everything that is needed, add this to one of the system
initialization scripts (e.g. /etc/rc.d/rc.local):
#----cut here----
# I2C adapter drivers
modprobe i2c-i801
# Chip drivers
modprobe lm85
# Warning: the required module coretemp 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 coretemp
/usr/bin/sensors -s
#----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.
