I just installed Linux (Ubuntu 8.04) and wanted to enable AMD's Cool 'n Quiet. I've looked around Google and people keep saying to enable it in the BIOS, but every time I go to the BIOS at startup, I don't see anything like "enable Cool 'n Quiet". I do see a "keep fan on at all times" thing, which is enabled, but I didn't want to disable that if it wasn't the right thing. How exactly would I change something like this in the BIOS?

What model computer? On laptops and most OEM computers AMD speedstepping is going to be enabled by default and they are not going to let you turn it off. Ubuntu 8 with the 2.6 kernel will have have the powersave module working so that the processor throttles back and that is all you need, really. Don't sweat it.
CPU Frequency Scaling
CPU Frequency Scaling allows you to change the speed at which your processor operates based on certain circumstances. For example if you are in battery mode you can set your processor to power save mode which will scale the CPU down to about 44% of its normal speed in order to conserve energy.
You can enable the CPU scaling monitor by right clicking the panel at the top of the screen and selecting "Add to Panel..." This will bring up a list of applets that you can enable on your panel. Scroll down until you find "CPU Frequency Scaling Monitor." Select it and click the "+Add" button. This will allow you to view the current frequency.

Did you install the generic Ubuntu or the specific amd64 version?
