Some motherboards, Intel desktop boards in particular, support a boot splash screen. Perhaps you could use that area to store stuff (after making sure the bios is set to NOT display the splash screen!) Or, maybe it would be really neat to hide data stenographicaly in an actual splash screen. Off the top of my head the images are 640x480 at 256 colors. Not sure if they're compresses, there's a special tool they have to use a bmp and put it in nvram. Of course all this isn't standardized :/ ~Jason --
