Hello everyone! My system hardware is Asus P5B with Intel Core Duo 2 e6600. I installed on it freeBSD 7.0 Release yesterday, but I don`t understand something. In Gnome there is CPU Frequency Scaling Monitor Witch it`s set to Performance, and the Cpu freq. is 2.39 Ghz, I can change it MANUALLY to other freq as can bee see it in the link`s above, but can not set to Economy :| In bios I have Intel Speed Step Enabled, and Cpu Freq set to AUTO. However, in Windows XP, my power scheme is set to Minimal Power Management And the cpu freq stay at 1.58-1.60, and when computer need more cpu power it AUTOMATICALY jump`s to 2.40 Ghz. The same thing happen`s in Ubuntu linux 7.10 and Debian Etch, the Cpu stay at ~1.60 Ghz and it jump`s auto when more Cpu resources is needed. I don`t undersntand why in linux and windows the cpu is automatically controlled by operating system and in freeBSD I need to set it manually. How can be this changed for freeBSD, to act as windows/linux at cpu freq scaling chapter? Thank`s in advance, and have a nice day! :) freeBSD Cpu Freq ScreenShot http://img291.imageshack.us/my.php?image=screenshotda4.png http://img87.imageshack.us/my.php?image=screenshot1yc6.png CPU settings Bios ScreenShot http://img99.imageshack.us/my.php?image=cartilasala0017nb9.jpg http://img100.imageshack.us/my.php?image=cartilasala0017fkq7.jpg
