2Connect the computer to an electrical outlet.
3Turn on the computer. When the DELL logo appears, press
immediately. If you wait too long and the Windows logo appears,
continue to wait until you see the Windows desktop. Then shut down
your computer and try again.
4When the boot device list appears, highlight the device from which
you want to boot and press .
The computer boots to the selected device.
The next time you reboot the computer, the normal boot order is restored.
Changing Printer Modes
Set the Parallel Mode option according to the type of printer or device
connected to the parallel connector. To determine the correct mode to use,
see the documentation that came with the device.
Setting Parallel Mode to Disabled disables the parallel port and the port’s
LPT address, freeing its interrupt for another device to use.

Serial Port allows you to map the serial port COM address or disable the
serial port and its address, freeing its interrupt for another device to use.
