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

Can you try with smi_cmd=0x82 instead before playing with -piix4 ?

It seems that there are a lot of laptops for which the int15 call return 0x80 for the command, but is actually 0x82 (those laptops also include an entry in the registry under Windows in order to get the correct parameter).
