*Setup GDT as part of boot process*

Type: ``bool``

Help
====

.. code-block:: none

    This option sets up the GDT as part of the boot process. However,
    this may conflict with some security scenarios where the GDT is
    already appropriately set by an earlier bootloader stage, in which
    case this should be disabled. If disabled, the global _gdt pointer
    will not be available.
