*Boot delay in milliseconds*

Type: ``int``

Help
====

.. code-block:: none

    This option delays bootup for the specified amount of
    milliseconds. This is used to allow serial ports to get ready
    before starting to print information on them during boot, as
    some systems might boot to fast for a receiving endpoint to
    detect the new USB serial bus, enumerate it and get ready to
    receive before it actually gets data. A similar effect can be
    achieved by waiting for DCD on the serial port--however, not
    all serial ports have DCD.
