Ok, I'll try that. As for upgrading to a multiboot2 header: maybe it's a good idea, but will not solve this particular problem. I think that grub2 simply can't boot a system in vga text mode, at least in my setting (uefi on 64 bits); a different multiboot header won't change that. To check that, I tried adding a mb2 header to boothdr.S but I get the same message from grub2: "warning: no console will be available to os". -- Andrea G.
