which model, which os you are using , based on this apply drivers

You can download the drivers from Dell WEB site, the support download page for your Dell latitude D600. Make sure you select your model laptop, better still type in the Service Tag number, it is printed on the label on the bottom of the laptop. Also make sure you select the Windows XP version of the driver for your Windows operating system.

If you are using windows xp service pack 2 then you need to install MSUAA first.
