imho, if you're not comfortable with ASM, try to avoid it ... you can achieve that quite easily by using GRUB, the faq-providen Bare Bones and basic inline function (in the FAQ too)

Enjoy the OS-FAQ!!! It's great stuff and easy to read (even if your a "uber-n00b").


@pype: how does one use the arguements supplied by the code in barebones?

Code: Select all

( void* mbd, unsigned int magic )

What i mean is: what does mbd point to (void* means NOTHING to me) and what is magic for? Thanks ;D



Cheers, DH.

Keep in mind that BareBones is a multiboot-aware kernel. The "magic" word it recieves is the multiboot magic word (should be 0xbadb0012 or something, check multiboot specs) and if that magic word is matched, then MBD should point to the Multiboot Data structure, which gives information about available memory, video modes, etc.

0x1BADB002 -- "One Bad Boot"

The Multiboot structure is in the Multiboot specification, which is part of the GRUB documentation (www.gnu.org/software/grub/)...
