Solving hardware installation problems

You might need to reconfigure the workstation when you add or remove hardware, such as an additional
diskette drive. If you install a Plug and Play (PnP) device, the operating system automatically recognizes
the device and configures the workstation. If you install a nonPnP device, you must reconfigure the
workstation after completing installation of the new hardware.
