Hello, I have an IBM R50 E with a Intel Celeron 1.4 Ghz processor installed with 10.3. Recently I discovered that simply loading the module p4_clockmod scales down the CPU-frequency to about 170MHZ and as needed scales the freq up. This helps saving battery power. What I would like to do is to set a lower limit beacuse sometimes the interaction feels quite slow because of the very low initial frequency. So what I would like to to is to say: Use eg 500MHZ as a lower limt for downscaling the CPU and scale up as needed. On my P4 Desktop I once had such an option where I could say eg: echo "500" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq to get this done but in 10.3 there is no such proc entry. Any other way to get this done?
