Grub & mmap

Post by JFF »

From the multiboot specification (http://www.gnu.org/software/grub/manual/multiboot/html_node/Boot-information-format.html)
Type is the variety of address range represented, where a value of 1 indicates available RAM, and all other values currently indicated a reserved area.
I got the mmap from grub and i get types from 1 to 4... Types 2-3-4 ares reserved.... but i'd like to know their use :P.

from my guestimations based on linux booting i have the following conclusions:

0 - usable
1 - reserved
2 - ACPI data
3 - ACPI NVS
