Unfortunatly, I had to find out that the current it87 driver resets the chip on init which switches the CPU/case fan to a very noisy full speed. So, after some grumpling :-) I decided to take things in my own hands and add some new features to the driver. First, I added a new mod parameter "reset_it87" which controls whether or not the chip is reset on module load (modprobe it87 reset_it=1, default) or not(modprobe it87 reset_it87=0). Since this worked out quiet nicely I decided to go one step further and also add the chips manual and automatic temperature controlled fan speed features (PWM etc.). Finally I also updated the doc to document the new features. Attached is a diff against the current cvs version. So long, Micha. -------------- next part -------------- A non-text attachment was scrubbed...
