Hi Some laptops, e.g., from Dell have a special button that they use to boot a special embedded OS for media only instead of the ordinary OS.
For my Dell XPS1330M I can determine if the Media button was pressed by first writing 0xf9 to port 0x70 and then testing bit 0x08 of port 0x71. It would be really nice if such a test could be enabled in grub so that grub can go directly to a specific menu alternative without showing the gui if the media button was pressed. Is this interesting? I'd like to contribute but I don't know where to start.
