I am using a Toshiba Satellite P105-6177 that was shipped with Vista and i just installed a dual boot with XP/Windows 7. I am unable to get sound or wifi on the xp partition. Is it a possibility that the 2 products having been shipped with Vista wont work with XP? I have tried the drivers on the toshiba website (for both Vista and 7...there are no xp) , and have had no luck. Curious if anyone else has had this problem or a similar one and could offer some help.
