If this option is not configured, the default coreboot logo (European Brown Hare) will used. You can use any image format supported by imagemagick, a list of which can be found [here](https://imagemagick.org/script/formats.php). The build process will automatically convert this to the format that EDK2 requires, which is an uncompressed BMP, in BMP3 format. It does this using imagemagick (`convert splosh.bmp BMP3:splash.bmp`). The newly formatted file will be the dimensions size as the original one. The build process will automatically do this conversion, so it can be supplied with any format that imagemagick can process (which is pretty much any!). This image will also be used as the BGRT boot image, which may persist through your OS boot process. See ACPI spec 6.3, 5.2.22 Boot Graphics Resource Table (BGRT), and Microsoft's documentation on BGRT positioning: Docs/Windows/Windows Drivers/Bring up guide/Boot screen components Accordingly, the image used should be no taller/wider than 40% of the display panel's native pixel height/width (or resolution set).
