I have laptop with Pentium M Dothan (stepping B0) 1.6GHz. There are no voltage/freq. paris in ACPI available, so i can't use frequency scaling under Linux. However i can press special button that raises CPU frequency from 600MHz to 1.6GHz. It's above keyboard, with ventilator sign. So maybe it is possible to detect which version of Dothan B0 i have? There are AFAIK four versions using different voltage/freq. pairs VID#{A,B,C,D}. I mean: detect which voltages are used after pressing ventilator button and then check which version of VID# it is. Other case: where do they keep this information? This ventilator button works (almost: i can't switch back to 600MHz), so it must be stored somewhere.. PS. I'm not subscribed to the list, please Cc me. -- Regards Sebastian ---------------------------------------------------------------------- TOUR DE POLOGNE: oficjalny serwis >>> http://link.interia.pl/f18b5
