Hardware installation problems

You might need to reconfigure the workstation when you add or remove hardware, such as an additional
optical drive. If you install a plug and play device, some operating systems automatically recognize the
device and configure the workstation. If you install a non–plug and play device, you must reconfigure
the workstation after installing the new hardware.
