        In many instances users will opt to run Openmediavault headless (no keyboard or monitor). Selecting any of the default <b>memory test</b> options will, after reboot, <b>disable</b> the Web Page console.  A monitor and keyboard would be required for changing Grub's boot order, to select the standard Debian kernel.
