for powerpc & i386-pc. This patch was more so started by Hollis Blanchard getting multiboot 2 working for powerpc and I added to it and cleaned it up. One of the ideas with this patch is to keep everything under one command for the user. So instead of having a "multiboot2" & "module2" command, I created a proxy like mechanism so that you have only one command for both multiboot 1 & 2 ... "multiboot". This is where "loader/multiboot_loader.c" comes from. I could have integrated things more but I figure the current approach will less likely break anything. So if your OS is multiboot 2 capable, the user would do the following to load it up from a grub prompt: grub> multiboot <location of kernel> <kernel args> grub> module <some image> <multiboot tag> <image arguments> grub> module <isome mage> <multiboot tag> <image arguments> grub ..... The other thing that this patch does is it begins to make the multiboot 1 code a bit more architecture agnostic so IF someone wanted to implement it on another architecture they can. A bit of file moving around and definition renaming is also apart of this patch. I have also taken the time to make sure that it does not break multiboot 1 loading on i386-pc. But mulitboot 2 may still need a little more testing and work for i386-pc. Powerpc multiboot 2 has been heavily tested and does work. |
