[SOLVED] Loading a custom boot code with GRUB
I want to know if I can such a thing. Assume, there are an Ext filesystem on some partition and some file "/image.img". I want GRUB(2) to switch on protected mode with flat model, load /image.img to some fixed address in memory and to jump to this address. Is it possible to configure GRUB so?

Yes, with the new Multiboot specification that is supported by GNU Grub2, this should work. The boot loader can switch to protected mode itself.
Here is a page with a small example.
