For fear of looking like an idiot, let me state that I am and idiot. I thought that this was going to be easy, and I didn't pay close enough attention to what I was doing. And now I think I've killed this laptop.

I'm working with an HP Pavilion dv9700. When it came to me, it had Windows Vista on it, and the owner hated it. She asked me to Wipe Vista off, and dual boot it with Windows XP and Linux Ubuntu. I'm not going to bother with Ubuntu yet, because I'm waiting for Jaunty to come out in a few days. So, XP. I figured that it wouldn't be hard, Windows computer, Windows OS, just format the hard drive, install XP, update any necessary drivers, and I'd be done. But, because I've never had any problems with upgrading or downgrading a computer, I didn't think to look up or write down all the specs. Yes, I'm an idiot. So I wipe out Vista, install Windows XP Professional, Service Pack 3. And now I have a laptop with no sound, no internet, no quick play buttons, and no image memory stick reader (the camera sticks). And that's just what I've found so far. The main one that's getting me right now is the internet. I don't know why it's not recognizing the hardware, but I don't know what kind of wired or wireless hardware is in the computer. So I'm not even sure what driver to try to install, or if there even is a driver that's compatible with XP. I think if I got her computer connected, I'd have better luck finding the drivers for the other devices. Any advice?
