sudo /usr/sbin/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): yes Probing for PCI bus adapters... Use driver `i2c-i801' for device 0000:00:1f.3: Intel 82801EB ICH5 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. 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. Next adapter: SMBus I801 adapter at eda0 Do you want to scan it? (YES/no/selectively): yes Client found at address 0x08 Client found at address 0x30 Client found at address 0x32 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'... Success! (confidence 8, driver `eeprom') Probing for `EDID EEPROM'... No Probing for `Maxim MAX6900'... No Client found at address 0x52 Probing for `Analog Devices ADM1033'... No Probing for `Analog Devices ADM1034'... No Probing for `SPD EEPROM'... Success! (confidence 8, driver `eeprom') Client found at address 0x69 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 `Winbond W83627HF' 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 `AMD K8 thermal 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 `ITE'... Yes Found unknown chip with ID 0x1404 Trying family `National Semiconductor'... No Trying family `SMSC'... Yes Found `SMSC LPC47M172 Super IO Fan Sensors' Success! (address 0xc00, driver `to-be-written') Trying family `VIA/Winbond/Fintek'... No 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 `eeprom' (should be inserted): Detects correctly: * Bus `SMBus I801 adapter at eda0' Busdriver `i2c-i801', I2C address 0x50 Chip `SPD EEPROM' (confidence: 8) * Bus `SMBus I801 adapter at eda0' Busdriver `i2c-i801', I2C address 0x52 Chip `SPD EEPROM' (confidence: 8) EEPROMs are *NOT* sensors! They are data storage chips commonly found on memory modules (SPD), in monitors (EDID), or in some laptops, for example. Driver `to-be-written' (should be inserted): Detects correctly: * ISA bus address 0x0c00 (Busdriver `i2c-isa') Chip `SMSC LPC47M172 Super IO Fan Sensors' (confidence: 9) I will now generate the commands needed to load the required modules. Just press ENTER to continue: If you want to load the modules at startup, generate a config file below and make sure lm_sensors gets started at boot time; e.g $ rc-update add lm_sensors default To make the sensors modules behave correctly, add these lines to /etc/modules.d/lm_sensors and run modules-update: #----cut here---- # I2C module options alias char-major-89 i2c-dev #----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. To load everything that is needed, execute the commands below... #----cut here---- # I2C adapter drivers modprobe i2c-i801 # Chip drivers modprobe eeprom # no driver for SMSC LPC47M172 Super IO Fan Sensors yet # sleep 2 # optional /usr/bin/sensors -s # recommended #----end cut here---- Do you want to generate /etc/conf.d/lm_sensors? Enter s to specify other file name? (YES/no/s): yes Done. biz@computer ~ $ lsmod Module Size Used by i2c_dev 5284 0 ipv6 188672 10 parport_pc 28100 0 parport 24296 1 parport_pc floppy 45380 0 pcspkr 1920 0 snd_intel8x0 23260 0 snd_ac97_codec 72800 1 snd_intel8x0 snd_ac97_bus 1280 1 snd_ac97_codec snd_pcm 45956 2 snd_intel8x0,snd_ac97_codec snd_timer 14852 1 snd_pcm snd 31716 4 snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer snd_page_alloc 6504 2 snd_intel8x0,snd_pcm i2c_i801 5836 0 i2c_core 11872 2 i2c_dev,i2c_i801 rtc 9172 0 radeon 103264 3 drm 53396 4 radeon intel_agp 17852 1 agpgart 19092 2 drm,intel_agp e100 25352 0 mii 3360 1 e100 tg3 92484 0 e1000 95264 0 nfs 96380 0 lockd 46472 1 nfs sunrpc 110940 2 nfs,lockd jfs 152524 0 raid10 19264 0 raid1 18720 0 raid0 6528 0 dm_mirror 15632 0 dm_mod 38584 1 dm_mirror sbp2 17732 0 ohci1394 27760 0 ieee1394 58232 2 sbp2,ohci1394 sl811_hcd 9248 0 usbhid 33120 0 ohci_hcd 15172 0 uhci_hcd 17608 0 usb_storage 60480 0 ehci_hcd 22312 0 usbcore 88388 7 sl811_hcd,usbhid,ohci_hcd,uhci_hcd,usb_storage,ehci_hcd bizz@computer ~ $ sensors No sensors found!
