Hello all,

I've tried to get the speedstep_smi module work on my  Vaio SR21k  with  
the params
smi_port=0xb2 and smi_cmd=0x80 but I've got an error message that my 
chipset is not supported.


Speedstep_detect  generates following output :

You need to boot on AC and battery and see if GPOs change.
Then, see if one bit change in between, you have then to note the number
of this bit.  This will be the gpo_hilo= number kernel option for
enabling the speedstep-piix4 module under Linux.

Should I try the PIIX4 module? If so, where can I find it for kernel 2.6.1 ?


Best regards
