Driver Problem

/g/ told me to go here, so here I go.
I just "downgraded" my laptop from vista to xp sp3, and installed all the necessary drivers, except for audio. My laptop is a Toshiba Satellite P205-S6237. After searching, I found that the one I had to install was Realtek WDM_R166, but when I install it, it gives me an error and cannot install. Could someone give some advice?

Oh Jesus, if he was really worried about that he could've gone to RealTek's website and see the exact same link posted there. Not all us 4channers are assholes posting viruses.

Did your laptop come with Vista? If it did, maybe there aren't any XP-ready drivers for that particular chip.
