I don't know how next solution is affected by patching. Using sensors-detect gives: No i2c device files found. Use prog/mkdev/mkdev.sh to create them. After creating appropriate /dev/i2c-x I run sensors-detect. The process didn't detect sensors expect (after starting /etc/init.d/lm_sensors start) odule Size Used by i2c_isa 1920 0 i2c_core 18064 1 i2c_isa As you see, the list doesn't contain smsc47m1 module as I expected. So I continued loading by hands, modprobe smsc47m1 lsmod Module Size Used by smsc47m1 8968 0 i2c_sensor 3072 1 smsc47m1 i2c_isa 1920 0 i2c_core 18064 3 smsc47m1,i2c_sensor,i2c_isa sensors command gives: smsc47m1-isa-0800 Adapter: ISA adapter fan1: 0 RPM (min = 5120 RPM, div = 1) fan2: 0 RPM (min = 2560 RPM, div = 2) Image of the driver si located at: /sys/bus/i2c/devices/0-0800/ where are files as follows: -r--r--r-- 1 root root 4096 Jun 10 18:55 alarms lrwxrwxrwx 1 root root 0 Jun 10 18:55 bus -> ../../../../bus/i2c lrwxrwxrwx 1 root root 0 Jun 10 18:55 driver -> ../../../../bus/i2c/drivers/smsc47m1 -rw-r--r-- 1 root root 4096 Jun 10 18:55 fan1_div -r--r--r-- 1 root root 4096 Jun 10 18:55 fan1_input -rw-r--r-- 1 root root 4096 Jun 10 18:55 fan1_min -rw-r--r-- 1 root root 4096 Jun 10 18:55 fan2_div -r--r--r-- 1 root root 4096 Jun 10 18:55 fan2_input -rw-r--r-- 1 root root 4096 Jun 10 18:55 fan2_min -r--r--r-- 1 root root 4096 Jun 10 18:55 name drwxr-xr-x 2 root root 0 Jun 10 18:55 power -rw-r--r-- 1 root root 4096 Jun 10 18:57 pwm1 -rw-r--r-- 1 root root 4096 Jun 10 18:57 pwm1_enable -rw-r--r-- 1 root root 4096 Jun 10 18:57 pwm2 -rw-r--r-- 1 root root 4096 Jun 10 18:57 pwm2_enable Stopping and working in the maximum regime can be done by echo 0 > pwm1_enable echo 0 > pwm2_enable echo 1 > pwm1_enable echo 1 > pwm2_enable The speed regulation can be controled writing a value from the range 0 - maximal speed, to 255 - stop spining, the polarity is reversed. Sorry Rudolf, but I don't understand you how can I play with pwmX_clock? I have files as listed above only. What is the fan speed? Is it possible to measure it? Thank you Rudolf for your advice. I lowered speed of fans and I can hear my typing fingers on keyboard, uhfff! I read somewhere that my chip has HW block. I don't know if I will be able to write support, but I can try. If you have any advice how to start, I will be glad. Cheers, Martin
