I use a Custom Filesystem - What Bootloader Solution is right for me?: Difference between revisions

To load the program, your instructions to GRUB will be something like the following:

 

kernel 0+BOOT_RESERVED_OFFSET

 

The kernel command loads a Multiboot compliant kernel, and in this case, we have specified an absolute number of sectors to load. The 'kernel' command can automatically detect if the file it's loading from the sectors is an ELF program. In other words, your 'bootloader' may even be a full ELF program, using this trick. In fact, you may even decide to place your kernel's executable image ''as the first N sectors, and have GRUB ELF load the kernel as absolute sectors, and not have to worry about parsing your custom FS at all.''
