I have an Optiplex 7020 pre loaded with Windows 7, I downgraded it to windows xp in order to use an app which only runs for windows xp. However, I couldn't find driver for ethernet, and Dell's website says that the machine is supproted only for windows 7 and up. Anybody who can help me make this machine work for windows xp?
