Add multiboot support.
I've been successfully using SeaBIOS as secondary bootloader. In more details
I have GRUB2-as-payload in flash together with coreboot. SeaBIOS binary is on
the HDD and loaded by GRUB when needed. This has an unfortunate consequence
that I have to keep vga oprom in flash even if usually I boot without it. This
patches makes bios.bin.elf multiboot executable with files passed as modules.
Example:
menuentry "SeaBIOS (mb)" --unrestricted {
root=ahci0,2
multiboot /bios.bin.elf
module /vgabios_x230.rom name=pci8086,0166.rom
}
the parameter name= specifies under which name SeaBIOS will see it.
