What does cat pwm?_enable print? echo 1 > pwm1_enable will switch it to manual mode. You need to set there manual mode first. Imho you can try first with pwmconfig script which is doing that for you. Addtitionally you may check documentation for the chip in kernel Documentation/hwmon/w83627ehf http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/hwmon/w83627ehf;h=ccc2bcb610686aaf44a0d38c5f67db44e8985e82;hb=HEAD Going for a holiday now, hope others will answer. Oh yeah I have written it for third time now ;) Rudolf
