Short answer: nope :-) That's not correct, if you would have read the description of the task you would know that the stage 1 boot loader loads the OpenBeOS "zbeos" equivalent from a BFS disk. Now, adding support to GRUB to be able to load from BFS is probably more complicated than only doing a very basic BFS loader (though it probably have to be done in assembly, due to the lack of 16bit real mode compilers).
It is actually quite simple: your code is loaded in 32 bit mode with linear 4gig segements and a20 enabled.> Loading by multibooot standard would i guess be an item for R2, since > it > probably requires modifying the boot procedure. But not using yet > another
I will have a closer look at the multiboot standard before defining the protocol between stage 2 and the kernel. If it's not too much work, I would try to be compliant, just to not have to change the protocol again in the forseeable future.
