[root@vmhost ~]# sensors-detect # sensors-detect revision 4171 (2006-09-24 03:37:01 -0700) 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 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 Do you want to scan it? (YES/no/selectively): Client found at address 0x08 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'), other addresses: 0x4b 0x4f Probing for `Winbond W83791SD'... No Probing for `Winbond W83627HF'... No Probing for `Winbond W83627EHF'...

Success! (confidence 1, driver `not-a-sensor') Client found at address 0x71 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 `Winbond W83627HF' at 0x290... No Probing for `Silicon Integrated Systems SIS5595'...

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 `ITE'... No Trying family `National Semiconductor'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Fintek'... Yes Found `Winbond W83627EHF/EHG Super IO Sensors' (but not activated) Probing for Super-I/O at 0x4e/0x4f Trying family `ITE'... No Trying family `National Semiconductor'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Fintek'... No 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 (and 0x4b 0x4f) Chip `Winbond W83793R/G' (confidence: 8) Driver `eeprom' (should be inserted): Detects correctly: * Bus `SMBus I801 adapter at 1100' Busdriver `i2c-i801', I2C address 0x54 Chip `eeprom' (confidence: 6) * Bus `SMBus I801 adapter at 1100' Busdriver `i2c-i801', I2C address 0x55 Chip `eeprom' (confidence: 6) EEPROMs are *NOT* sensors! They are data storage chips commonly found on memory modules (SPD), in monitors (EDID), or in some laptops, for example. I will now generate the commands needed to load the required modules. Just press ENTER to continue: 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-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 eeprom # sleep 2 # optional /usr/local/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?
