[SeaBIOS] [PATCH 0/3] Add multiboot support to SeaBIOS

[Vladimir 'phcoder' Serbinenko]

Hello, all. 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. The following series of patches make
bios.bin.raw multiboot executable with files passed as modules. Example:
menuentry "SeaBIOS (mb)" --unrestricted {
   root=ahci0,2
   multiboot /bios.bin.raw
   module /vgabios_x230.rom name=pci8086,0166.rom
}

the parameter name= specifies under which name SeaBIOS will see it.
