Well - P4 chips are power hungry - so that could be an unsolveable problem. Is it a mobile P4? If so - it should support speedstep. Does it work? Try the following: # grep MHz /proc/cpuinfo model name : Intel(R) Pentium(R) M processor 1600MHz cpu MHz : 598.068 # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver centrino # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor userspace If its not working - check the following on how it set if up for P-III. http://www.redhat.com/archives/fedora-list/2004-November/msg04371.html You might have to change 'speedstep-smi' to 'peedstep-ich' for P4 Satish
