OK, I have now installed the latest version of lm_sensors 2.10.4. Here is the snip from sensors-detect: 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 LPC47B357 Super IO' (no information available) 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 Now i ran the prog/hotplug/unhide_ICH_SMBus and here is the output: Enabling SMBus PCI device ... Rescanning the bus ... Loading i2c-i801 ... 00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus (rev 04) Done! Remember: system suspend/resume is no longer safe to use. I do not suspend and/or resume the machine, so I guess things will be OK...... Rerunning sensors-detect found everything :) [root at scatha lm_sensors-2.10.4]# sensors adm1023-i2c-0-18 Adapter: SMBus I801 adapter at fc00 Board Temp: +43??C (low = -55??C, high = +127??C) CPU Temp: +47??C (low = -55??C, high = +61??C) adm1023-i2c-0-4c Adapter: SMBus I801 adapter at fc00 Board Temp: +42??C (low = -55??C, high = +127??C) CPU Temp: +48??C (low = -55??C, high = +61??C) Thanks for your help Juergh!!! Once again you helped out. Last time was the IPMI sensors on my Intel SHSR server. Keith
