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¶

MULTIBOOT && X86

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
