 *Globally assignable* keys are:
 * `TIMEOUT` - Specifies the timeout in seconds before the first *entry* is automatically booted.
 * `DEFAULT_ENTRY` - 0-based entry index of the entry which will be automatically selected at startup. If unspecified, it is `0`.
-* `GRAPHICS` - If set to `yes`, do use graphical VESA framebuffer for the boot menu.
-* `THEME_BLACK`, `THEME_RED`, `THEME_GREEN`, `THEME_BROWN`, `THEME_BLUE`, `THEME_MAGENTA`, `THEME_CYAN`, `THEME_GREY`, `THEME_WHITE` - Specifies the colors used by the terminal (RRGGBB). Ignored if `GRAPHICS` is not `yes`.

+* `BACKGROUND_DRIVE` - Drive where to find the background .BMP file. Assume boot drive if unspecified. Ignored if `GRAPHICS` is not `yes`.

 *Locally assignable (non protocol specific)* keys are:
 * `PROTOCOL` - The boot protocol that will be used to boot the kernel. Valid protocols are: `linux`, `stivale`, `stivale2`, `chainload`.
