With Linux, is there a way to retrieve the processor model without taking information from bios? I don't know which processor is really mounted. I want to set up the right processor timing, but I don't know the processor type. Every time I change the timing for the processor in BIOS another processor type is determined (I should be an Athlon XP +1500, I think, but I don't know really).

I think with

less /proc/cpuinfo

the results depends on the timing that is set in bios.

So could you tell me how I can find out which processor is really mounted?

What indicator do you have that the processor type is changing? – Joe Internet Jul 31 '11 at 17:54
My bios shows the processor type depending on the clock settings and the resulting frequency. If I set the base-timing to 100 MHz the resulting cpu-speed is 1 GHz and the BIOS show "AMD Athlon XP". If I set the base-timing to 133 MHz the resulting frequency ist 1,333GHz the BIOS shows "AMD Athlon XP 1500+". Now I am a bit confused which processor is really mounted. – Martin Jul 31 '11 at 18:40
Does less /proc/cpuinfo also show different results? – Joe Internet Jul 31 '11 at 19:00
yes it does show the same names like the bios shows – Martin Jul 31 '11 at 19:04
Ok, what do you get if you run sudo dmidecode -t processor? Does it change for each setting, or stay the same? – Joe Internet Jul 31 '11 at 19:12

There is some information in /proc/cpuinfo and /sys/devices/system/cpu.

Most of the files in there behave like text file and can be viewed with e.g. cat. They also be fairly easy to parse automatically.

I know these locations, but I think their contents base on the information gathered from BIOS – Martin Jul 31 '11 at 18:44
No, the kernel probes those informations directly from the hardware at startup time. Additional details can sometimes be found in the first lines of dmesg output. – Luke404 Mar 27 '13 at 22:15
