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 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, use the Add
Hardware Wizard and follow the instructions that appear on the
screen.
