@ -54,12 +54,9 @@ Some keys take *URIs* as values; these are described in the next section.
* `GRAPHICS` - If set to `yes`, use a graphical framebuffer for the boot menu, else use text mode. Ignored with Limine UEFI, forced to `yes`.
* `MENU_RESOLUTION` - Specify screen resolution to be used by the Limine menu in the form `<width>x<height>`. This will *only* affect the menu, not any booted OS. If not specified, Limine will pick a resolution automatically. If the resolution is not available, Limine will pick another one automatically. Ignored if `GRAPHICS` is not `yes`.
* `MENU_BRANDING` - A string that will be displayed on top of the Limine menu.
* `MENU_FONT` - URI path to a font file to be used instead of the default one for the menu and terminal. The font file must be a code page 437 character set comprised of 256 consecutive 8x16 glyphs bitmaps (4096 byte font file). Each glyph's bitmap must be expressed left to right (1 byte per row), and top to bottom (16 bytes per whole glyph).
* `TERMINAL_FONT` - Alias of `MENU_FONT`.
* `MENU_FONT` - URI path to a font file to be used instead of the default one for the menu. The font file must be a code page 437 character set comprised of 256 consecutive 8x16 glyphs bitmaps (4096 byte font file). Each glyph's bitmap must be expressed left to right (1 byte per row), and top to bottom (16 bytes per whole glyph).
* `THEME_COLOURS` - Specifies the colour palette used by the terminal (AARRGGBB). It is a `;` separated array of 10 colours: black, red, green, brown, blue, magenta, cyan, gray, background, and foreground respectively. While an alpha transparency value can be specified for every colour, it is ignored for all but background. Ignored if `GRAPHICS` is not `yes`.
* `THEME_COLORS` - Alias of `THEME_COLOURS`.
* `THEME_BACKGROUND` - Alias of the background value in `THEME_COLOURS`.
* `THEME_FOREGROUND` - Alias of the foreground value in `THEME_COLOURS`.
* `THEME_MARGIN` - Set the amount of margin around the terminal. Ignored if `GRAPHICS` is not `yes`.
* `THEME_MARGIN_GRADIENT` - Set the thickness in pixel for the gradient around the terminal. Ignored if `GRAPHICS` is not `yes`.
* `BACKGROUND_PATH` - URI where to find the background .BMP file. Ignored if `GRAPHICS` is not `yes`.
