Hello,
I've been attempting to control the fan speed on a
Biostar iDEQ 210V computer which has an IT8705F Super
I/O chip. Does the it87 module ( which controls the
IT8705F chip ) enable pwm motor fan control? I have
read similar queries but haven't read any definitive
answers.

The it87 documentaton says this: "The fan control
features can be enabled by setting bits 0-2 of the
fan_ctl register to 1." However, the documentation is
silent on how to set this these bits. Can these
register bits be set with isaset? Can they be set
somehow in the /etc/sensors.conf file?

Similarly, the it87 documentation says this: "Bit 7 of
the pwm[1-3] registers enables/disables the chips
automatic temperature control mode for the specified
fan." But again, it has no mention on how to set or
read these registers.

Any help would be apprecitated. By the way, I can read
the fan speed. Since I'm sure other people are trying
to do the same thing I will set up the following web
page if I come up with a solution:
      biostar-linux.com/fancontrol.html
