I'm running Centos 4.2 x86_64 on a SuperMicro X6DHI-G2 mobo (http://www.supermicro.com/products/motherboard/Xeon800/E7520/X6DHi-G2.cfm). I have installed the latest version of lm_sensors but my temps reported back are all -48.0C which is incorrect of course, my BIOS reports temps of 44/44/43C. Any ideas on what I'm doing wrong or is my setup just not supported? Thanks for any help. Log of sensors-detect below (I pressed enter at all prompts): [root at localhost ~]# sensors-detect Hexadecimal number > 0xffffffff non-portable at /usr/local/sbin/sensors-detect l ine 2108, <INPUTFILE> line 15. # sensors-detect revision 1.413 (2006/01/19 20:28:00) This program will help you determine which I2C/SMBus modules you need to load to use lm_sensors most effectively. You need to have i2c and lm_sensors installed before running this program. Also, you need to be `root', or at least have access to the /dev/i2c-* files, for most things. If you have patched your kernel and have some drivers built in, you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. 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. You do not need any special privileges for this. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver `i2c-i801' for device 00:1f.3: Intel 6300ESB Probe succesfully concluded. We will now try to load each adapter module in turn. Load `i2c-i801' (say NO if built into your kernel)? (YES/no): Module loaded succesfully. 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. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. Do you want to load it now? (YES/no): Module loaded succesfully. We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will 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. That often includes address 0x69 (clock chip). Next adapter: SMBus I801 adapter at 1100 Do you want to scan it? (YES/no/selectively): Client at address 0x2d can not be probed - unload all client drivers first!

(YES/no/selectively): Some chips are also accessible through the ISA bus. ISA probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though.
