2 Connect the computer to an electrical outlet.
3 Turn 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.
4 When 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.

serial port and its address, freeing its interrupt for another device to use.
