/**
* @brief Shared bootloader configuration.
*
* Sets up menus that present the boot options for both the EFI
* and BIOS loaders. If you want to tweak ToaruOS's bootloader
* to boot some other Multiboot1-compliant OS, start here.
*
* This is also the place to add new default startup configs,
* add toggles for command line options, and so on.
