Yes, this is a 4-wire fan. The chassis fan connector is 3-wire though, and I can't seem to control the speed of a 3-wired fan by writing to pwm2. > So it's really a matter of finding the right scaling factors.

Here: http://spuk.denardin.org/Asus_M5A78L-M-v0603_DSDT.bin No hurry from me, I'm gonna use asus_atk0110 for reading, and it87 only for PWM control or now. I'm trying making sense of the formula in the RVLT method. How can I use isadump to get the raw values for checking the formula?
