so far the multiboot support is not included in the documentation.
This small patch changes docs/Runtime_config.md to include multiboot.
I think adding how to use multiboot with Grub would be nice, but this
does not seem to fit to the content of Runtime_config.md.
Do you have any suggestions where to put it?
This example shows how to start SeaBIOS from
Grub2 via multiboot.
SeaVGABIOS is passed as a module.
module /vgabios.bin name=vgaroms/seavgabios.bin
