Detailed Description

Memory Map.

The boot loader queries the BIOS for a memory map and stores its result in (something like) a linked list. However, this list may not be complete, can have contradictory entries and does not take the location of your kernel or any boot modules into account. (Anyways, it is still the best memory map you will have in StuBS...)

Note
Needs to be enabled explicitly by setting the MULTIBOOT_MEMORY_INFO flag in the multiboot header (see boot/multiboot/config.inc)!
