Hello @yyymmm

I patched my Mogul Magic Dragon (RX580 2048) according to your documentation and included the GOP.
It is running on a Mac Pro 5,1 with Sonoma (OCLP 1.4.2) 2x Xeon 5690. Both Monitors are working (Cinema 30 and Cinema 27 LED). The Mac Pro 5,1 is GOP enabled, so no need to patch any PC Graphics Card with GOP for Bootpicker.
Some issues occured:
- Windows 11 is only running in Compatibilty mode (RX570 needs additional driver installation)
Tested with different drivers (always after ddu 3 times in safe-mode) original current AMD Drivers, Bootcampdrivers legacy and latest). And for sure SMC reset and NVRAM Reset 4 times before testing.
- Sonoma works so far even with Acceleration, but there is no sound over Display Port to the Cinema LED 24
Works with original (non China MSI RX570 and Vega 56)
But for me the real issue is the Windows driver not working.
Maybe you can find something I did wrong and help me out.

Many thanks in advance.

The GPU-Z shows the original rom working with the legacy Bootcampdrivers. (for sure not recognized in Mac OS)

Hello @yyymmm

Thank you for your effort.

Unfortunately it's the same situation than before.
- The Windows driver is not loading
- Mac OS Sonoma works fine
- My issues with the sound were related to the Cinema LED and had nothing to do with the bios (worked after unplugging AC also with my patched version of the rom).

Just restored the original China Rom and Windows 11 works again without any issues and as expected Sonoma isn't.
I thought that nothing was wrong with my self patched rom. So there must be another issue with this special card.

Best regards
René
