[tlinux-users 00132] Re: Request a new info: fan control documentation for Toshiba A300

[Ilyes Gouta]

Hi Azael,

Thanks for the heads-up!

You mentioned that I have to put the proper PCI ids at some point. How
these PCI ids are going to be used? Me too, I have an ICH8 controller
in my laptop.

Regards,
Ilyes Gouta.
