└─> Acer Aspire One temperature and fan driver

This is a driver for Acer Aspire One netbooks. It allows to access
the temperature sensor and to control the fan.

After loading this driver the BIOS is still in control of the fan.
To let the kernel handle the fan, do:
echo -n enabled > /sys/class/thermal/thermal_zoneN/mode
where N=0,1,2... depending on the number of thermal nodes and the
detection order of your particular system. The "type" parameter
in the same node directory will tell you if it is "acerhdf".

For more information about this driver see

If you have an Acer Aspire One netbook, say Y or M
