Solving front panel component problems If you are experiencing problems with one of the front panel ports, you might be able to try your device in the corresponding port on the back side of the computer.

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 PnP (Plug 'n Play) device, Windows XP automatically recognizes the device and configure the workstation. If you install a non-PnP device, you must reconfigure the workstation after completing installation of the new hardware. ENWW Troubleshooting scenarios and solutions 151
