*Generate multiboot header*

Type: ``bool``

Help
====

.. code-block:: none

    Embed a multiboot header in the output executable. This is used
    by some boot loaders (e.g., GRUB) when loading Zephyr. It is safe
    to leave this option on if you're not sure. It only expands the
    text segment by 12-16 bytes and is typically ignored if not needed.
