Hi, The XP drivers for your laptop are available at the HP site http://www.hp.com/. Click on "Software & Driver Downloads" leftside near the bottom, enter your product "Pavilion dv9205us", click on "Microsoft Windows XP". May I suggest that you download them now even if still running vista and then burn to a CD or copy to a flashdrive. That way when you have downgraded to XP, the drivers are readily available. Hope this be of help/idea. Post back how things turns up or should you need additional information. Good luck and kind regards.
