I have a powercolor red dragon RX 580 8GB that, when I boot after installing opencore, still does not show a boot screen. Now this IS a dual BIOS card so I need to know if I need to have it on the 1st BIOS position instead of the 2nd position like it is now (its on the 2nd position as I bought this as a used mining card and it has a mining vbios installed on the 1st position of the switch, at least as far as I know I haven't actually confirmed if that is the case or not) So if any of ya'll have any info that can help me that would be greatly appreciated. I am going to be flashing a stock BIOS on the 1st switch position later so if that works I'll update this thread.
