for Tianocore, use the latter only. Needs to be a 24bpp windows BMP, no larger than the width of the screen and 75% of the height (the image is centered 38.2% down from top as per BGRT spec). Gimp can be used too but likely will have a pallette shift if a non B&W image used

Hello,
Using the VBT route for graphics initialisation and TianoCore as the payload gives two options within .config for splash screen:
CONFIG_BOOTSPLASH: This option shows a graphical bootsplash screen. The graphics are loaded from the CBFS file bootsplash.jpg.
CONFIG_TIANOCORE_BOOTSPLASH_IMAGE: Select this option if you have a bootsplash image that you would like to be used. If this option is not selected, the default coreboot logo (European Brown Hare) will used.
Do I need to define both? What are the requirements for the images in terms of size, colour depth, etc?
