At first sorry form my terrible english - i'm not native speaker

I posess notebook with celeron M which is going on 1.3GHz. Usually this power isn't important (only when emerging

) . Is it possible to lower it frequency??
My notebook is Fujitsu-Siemens Amilo M 7400 based on i855GM chipset. Higher models have Pentium M, so it's upgredable (

).
Have somebody done this??

Thank You for reading

Pawel

AFAIK, the difference between celeron M and pentium M processors is -- besides the CPU clock frequency -- the ability to do speedstep. So you won't have luck here, sorry.

yes, lower cache L2 and speedstep. But I heard that the 855 chipset has ability to set your own multiplier - usually in bios, but mine bios hasn't this option. I thought that is possible to do it in software...

AFAIK, this is a built-in multiplier on the CPU which you can't modify. I may be wrong, though...

Use a newer kernel. I've got a Centrino 1.7 (Dothan B0) and it works perfectly with 2.6.8.1-mm4, but not with just plain 2.6.8.1.
