I need the update as I am not able to enable Intel SpeedStep on the machine, I'm on Debian and the output from cat /proc/cpuinfo is blank where it says Power Management. This is with a Pentium M 755 2.0ghz CPU, which most certainly has SpeedStep enabled. Trying to load the speedstep_centrino module fails, as well as everything else I've tried for months now.
In Windows, I only tried XP, the outcome is the same, no cpu-throttling. As a result, the fan is always on and CPU temps are 65-60C when idle.
I have come to believe the problem is caused by a buggy BIOS that somehow fails to supply the OS with information on what kind of cpu-throttling is supported.
Here is everything I know about the machine:
Text on motherboard:
MB05T-MB05TMB VER 03
From debian hwinfo:
Phoenix Technologies LTD
Montara System SV/CR Board
chipset: Intel 855GM Montara-GM
part number: 82855GM (GMCH)
Intel ID: 0x6d6
Any help in locating a BIOS update is greatly appreciated.
