Hi! Some ideas regarding the possibility to use native Mac tools for your RX580 graphics card BIOS update task:

Why do you need a boot screen? That sounds like some very low priority moment to have graphics? > I got freedos to boot from the disk, and got ATIFlash > running, but it’s only seeing the original card. Does that mean you booted FreeDOS on the raw hardware of the Mac? How have you managed to do that? And what does original card mean, do you have TWO graphics cards? Why not remove the non-ATI while you do that BIOS update?? And actually why is having a boot screen on the non-ATI card not sufficient for you? ;-) In case you prefer another language then English and this is why your mails often feature extremely short descriptions of the situation: Please write in your native language, by exception. There are people speaking various languages on this list so you may be understood better than in English :-) Thank you!
