.. title:: MULTIBOOT_INFO

.. option:: CONFIG_MULTIBOOT_INFO

*Preserve multiboot information structure*

Type: ``bool``

Help
====

Multiboot passes a pointer to an information structure to the
kernel entry point. Some drivers (e.g., the multiboot framebuffer
display driver) need to refer to information in this structure,
and so set this option to preserve the data in a permanent location.

Direct dependencies
===================

\ :option:`MULTIBOOT <CONFIG_MULTIBOOT>` && \ :option:`X86 <CONFIG_X86>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

No defaults. Implicitly defaults to ``n``.
