hard drive.)

too long and the Windows logo appears, continue to wait until you see the Windows desktop.
Then shut down your computer and try again.

When the boot device list appears, highlight the device from which you want to boot and
press <>Enter>.
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.
