Solving Hardware Installation Problems

You may need to reconfigure the computer when you add or remove hardware, such as an
additional drive or expansion card. If you install a plug and play device, Windows XP Home/
Professional will automatically recognize the device and configure the computer. If you install a
non–plug and play device, you must reconfigure the computer after completing installation of the
new hardware. In Windows XP and Vista, use the Add Hardware Wizard and follow the
instructions that appear on the screen.
