Solving Hardware Installation Problems

You may need to reconfigure the computer when you add or remove hardware, such as an
additional diskette drive. 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.
