Given this is an external DSL modem, you really don't need to install drivers for it. Most external DSL modems are stand alone units these days (unlike regular dial-up modems which required a serial port). XP drivers are generally NOT recommended unless there's no other option. Can you connect to the modem by way of an internal web interface? You might want to consider the purchase of a cheap router with a firewall built in. Those all have a web interface and can be used to connect your computer(s) to the modem with few issues.
