Hello, I've got an Intel mainboard D845GEBV2 as replacement for my Asus P4B-266SE (that ASB100 mess). I've mounted it, gone through the configs and sensors-detect said I should use the lm85 driver. With lm85 it seem to work well, except I cannot change anything in the proc interface. The values reported seem correct but all changes (e.g. echoing values to the pwm# registers) are ignored... As far as I can see from the BIOS, that board has settings for fan control and speed. I guess that the BIOS initializes the sensors during POST but as far as I could see, there was no change to the problem even I deactivate the settings from the BIOS. I've took a look at the board and found following devices I could think of being attached to the bus: LM 85 BIMQ, ICS 950227 AF, FW 82801 DB, PC 87382 IBU/VLA and the eeprom from the RAM. Intel claims there is an SMSC LPC47M172 on board. Here is the output of what I could get from my system.
