Thanks for the comments. Here are the result of my researchs.
I verified what happens with this board: K6XV3+/66 rev. BB+ from DFI.COM. Under Win98, people seems to change the parameters with CPUCool. So, I think, clock frequency (or FSB) and fan can be modified with other OS.
I have acpi and cpufreq as extension on boot.
No modules are loaded automatically (lsmod dont show acpi etc.). So far I see, I had a boot option in menu.lst noapci; I will change it to see what happens.
When I make sudo modprobe acpi-cpufreq, the message "modprobe: cant load module acpi-cpufreq (kernel.tclocal/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko.gz): no such device.
I post now the dmesg; perhaps somebody see something here?
