Include powersave, performance and set the Default CPUFreq governor to userspace. DOwn in the make menuconfig screen you have to choose your cpu wich fits your system ! load the newly added modules and you should find either one of the following options (depends on your configured modules): echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed or echo 600000 > /proc/sys/cpu/0/speed or echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor the 600000 is just an example. check out your frequency range by: if you have mounted your sysfs, you should see the dir (and your frequency-range min, max): /sys/devices/system/cpu/cpu0/cpufreq$ ls cpuinfo_max_freq scaling_driver scaling_min_freq cpuinfo_min_freq scaling_governor scaling_setspeed scaling_available_governors scaling_max_freq hope this helps christian Am So, den 18.01.2004 schrieb Luca Capello um 19:04: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hello, > > on 01/18/04 18:10, Mattia Dongili wrote: > > no, it doesn't.
