Default apmd : Operation not supported

Hi,

I have an AMD Athlon(tm) II X3 455 Processor and I when I try to have cpu scaling here is what I get :
Code:
# apmd -A
cannot open device file `/dev/apmctl` : Operation not supported by device.
Does it mean that this feature isn't support for this processor, or is it linked to the BIOS of the motherboard, a 880GA-UD3H GIGABYTE ?

I couldn't find any relevant error in dmesg.

Thanks

As posted some time back on tech@, newer motherboards (especially multi-processor...) will be configured as ACPI depending upon SMBIOS versions:

If you want us to look at it, post the entire output of dmesg(8). Otherwise, we have insufficient information to comment further.

In fact, OpenBSD is not installed on this computer anymore. I couldn't get cpu scaling to work on it with 4.9. (Didn't try very hard though).

I wanted to see if it worked with 5.0 when I booted from the install disk (install50.iso).
The thing is I first downloaded the i386 version because I aimed to install OpenBSD on a usb stick to then install to my i386 netbook.
From this cd I had the error I posted.

Then I tried again with the amd64 version to find that apmd is not in /sbin.

I wanted to post the dmesg output, but I have first to find how to mount an ext2fs (or whatever works) drive from the installation disk shell.

It seems the answer is here (this article was about 4.8) :
http://undeadly.org/cgi?action=artic...20101224204626
* Speed scaling is unavailable for this processor family (AMD K10)

From FreeBSD :
Code:
%dmesg|grep -i amd
    root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
CPU: AMD Athlon(tm) II X3 455 Processor (3314.72-MHz K8-class CPU)
  Origin = "AuthenticAMD"  Id = 0x100f53  Family = 10  Model = 5  Stepping = 3
  AMD Features=0xee500800<SYSCALL,NX,MMX+,FFXSR,Page1GB,RDTSCP,LM,3DNow!+,3DNow
I found this too :
