/***************************************************** *** to set p4_clockmod [my dell gx260 pc] on reboot ** *****************************************************/ step3/3:.............................Now that [p4_clockmod.ko] works my dell gx260. I will want to load [p4_clockmod.ko] on boot. To do this on a Debian based system like K/X/Ubuntu put the following line in the /etc/modules file. =========== line @ /etc/modules file: p4_clockmod #thats it powertop must of set it to ondemand.

analyzing CPU 0:
driver: p4-clockmod
CPUs which need to switch frequency at the same time: 0
hardware limits: 283 MHz - 2.27 GHz
available frequency steps: 283 MHz, 567 MHz, 850 MHz, 1.13 GHz, 1.42 GHz, 1.70 GHz, 1.98 GHz, 2.27 GHz
available cpufreq governors: powersave, conservative, ondemand, userspace, performance
current policy: frequency should be within 283 MHz and 2.27 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 283 MHz.
