No I want to replace the boot image in my UEFI BIOS whatever. It's still the Purism white rectangle on black background even though I'm running Debian 12. I'd love to see a logo of mine, or my face or something silly like that. How do I get that installed? Or no image, like in the good old days. I feel like the answer is somewhere in here: https://www.coreboot.org/SeaBIOS#Adding_a_graphical_%22bootsplash%22_image
