# sensors-detect revision 3.4.0-4 (2016-06-01) # System: Gigabyte Technology Co., Ltd. G41M-Combo # Kernel: 3.10.0-862.11.6.el7.x86_64 x86_64 # Processor: Intel(R) Celeron(R) CPU E1400 @ 2.00GHz (6/15/13) 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. Some south bridges, CPUs or memory controllers contain embedded sensors. Do you want to scan for them? This is totally safe. (YES/no): yes Silicon Integrated Systems SIS5595... No VIA VT82C686 Integrated Sensors... No VIA VT8231 Integrated Sensors... No AMD K8 thermal sensors... No AMD Family 10h thermal sensors... No AMD Family 11h thermal sensors... No AMD Family 12h and 14h thermal sensors... No AMD Family 15h thermal sensors... No AMD Family 16h thermal sensors... No AMD Family 15h power sensors... No AMD Family 16h power sensors... No Intel digital thermal sensor... Success! (driver `coretemp') Intel AMB FB-DIMM thermal sensor... No Intel 5500/5520/X58 thermal sensor... No VIA C7 thermal sensor... No VIA Nano thermal sensor... No Some Super I/O chips contain embedded 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/ITE'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Nuvoton/Fintek'... No Trying family `ITE'... Yes Found `ITE IT8720F Super IO Sensors' Success! (address 0x290, driver `it87') Probing for Super-I/O at 0x4e/0x4f Trying family `National Semiconductor/ITE'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Nuvoton/Fintek'... No Trying family `ITE'... No Some systems (mainly servers) implement IPMI, a set of common interfaces through which system health data may be retrieved, amongst other things. We first try to get the information from SMBIOS. If we don't find it there, we have to read from arbitrary I/O ports to probe for such interfaces. This is normally safe. Do you want to scan for IPMI interfaces? (YES/no): yes Probing for `IPMI BMC KCS' at 0xca0... No Probing for `IPMI BMC SMIC' at 0xca8... No Some hardware monitoring chips are 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): Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now? (YES/no): Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7 Module i2c-dev loaded successfully. Next adapter: i915 gmbus ssc (i2c-0) Do you want to scan it? (yes/NO/selectively): Next adapter: i915 gmbus vga (i2c-1) Do you want to scan it? (yes/NO/selectively): Next adapter: i915 gmbus panel (i2c-2) Do you want to scan it? (yes/NO/selectively): Next adapter: i915 gmbus dpc (i2c-3) Do you want to scan it? (yes/NO/selectively): Next adapter: i915 gmbus dpb (i2c-4) Do you want to scan it? (yes/NO/selectively): Next adapter: i915 gmbus dpd (i2c-5) Do you want to scan it? (yes/NO/selectively): Next adapter: SMBus I801 adapter at 0500 (i2c-6) Do you want to scan it? (yes/NO/selectively): Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `it87': * ISA bus, address 0x290 Chip `ITE IT8720F Super IO Sensors' (confidence: 9) Driver `coretemp': * Chip `Intel digital thermal sensor' (confidence: 9) Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes Unloading i2c-dev... OK
