The GRUB2 payload reads its runtime configuration file from etc/grub.cfg

stored in the CBFS on the flash ROM chip. Without that, it’ll just drop

into a rescue shell.

This configuration may need to be coreboot specific.

Select this option, if you want to include the GRUB2 runtime

configuration file into CBFS as `etc/grub.cfg` automatically.

You will be able to specify the path of the configuration file later.

Enable this to allow the access to the boot menu of SeaBIOS. It

Please use this with caution.
