The driver is built in to Windows XP! Just have the pad plugged into the gameport, go to Control Panel's Game Port applet, click add controller, click Microsoft Sidewinder (auto-detect), and Windows will install the built in driver for it. You won't be able to load profiles, as there is no game controller software for this controller that is compatible with Windows XP. However, the pad works perfectly, as well as the pass-through for two gamepads or a joystick (like the Precision Pro).
