Hello Guys:
I have a Problem with Mac Pro 4.1(5.1).
I have flashed 2x Graphic Cards wit mac EFI ROM to have a Boot Screen:
MSI R9 280 GAMING 3G
MSI R9 280X GAMING 3G
Both Graphic Cards works very good in MacOS Mojave, but as soon i start Windows 10 on the Mac Pro, i get a black Screen and the Mac Pro reboots.
With the stock Windows GPU BIOS on both cards - Windows boots just fine.
What can it be?
Thanks
