Wow! Didn't mean to start a "tech war" here (point's at the long thread arguing the use of p4-clockmod). >> It works in Windows XP, so I'm not sure if it's only a BIOS issue. > > On Windows platform drivers sometimes provide a replacement DSDT > that might enable cpufreq.

I don't remember installing any special driver for Windows XP. Since you claim that as a possibility, is there something that I can look for to check if this is the case? The reason I'm questioning this so much is because I plan to contact Shuttle tech support and try to get them to fix this if it really is a BIOS issue. But I need valid points to make sure they don't pass on the blame and slip away. They do seem to release BIOS updates now and then so I'm hoping I can coax them to release one. >> If it's not that simple, then care to impart some knowledge? > > If you can't get your BIOS to provide the necessary methods > then useful Linux cpufreq won't work.

I definitely don't want to use anything that will have a drastic effect on performance.
