If it was there, the LM96000 chip would appear at address 0x2c, 0x2d or 0x2e. There's nothing at any of these addresses in your case, so the chip doesn't appear to be connected to this bus. No amount of effort will make the lm85 driver work in this case. In fact the Intel documentation is pretty clear on the fact that the LM96000 chip is connected to the PC87427 Super-I/O chip and not the ICH6R south bridge. So you will need a completely different set of drivers to make it work. Support for this configuration is not yet in Linux mainstream but additional patches exist and we had some reports of success already. See the following archived threads: http://lists.lm-sensors.org/pipermail/lm-sensors/2005-June/012825.html http://lists.lm-sensors.org/pipermail/lm-sensors/2005-November/014401.html And this site: http://bmcsensors-26.sourceforge.net/ Beware that it'll involve switching to a more recent kernel, patching it and recompiling it from source. -- Jean Delvare
