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 2000 and 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 2000, select
the Add New Hardware icon in the Control Panel (for Windows
XP, use the Add Hardware Wizard) and follow the instructions that
appear on the screen.
