MP 1,1-5,1 MacPro5,1: BootROM thread | 144.0.0.0.0

[tsialex]

Hello, I owned a 4,1 machine for a bit over 10 years. I also have a metal capable rx480 flashed with EFI compatible firmware. Early on I did the 4,1 -> 5,1 hack and my bootROM has been upgraded to 144.0.0.0.0 however, I booted windows 10 in EFI mode before it was widely known the issues this causes. My machine is still booting os 10.14 but I hope to get a reconstruction service. Alexandre, could you send me a PM?

PM sent with instructions/files required/service fee/turnaround time.

As I posted, @tsialex did an amazing job with my two Mac Pro 5,1's!! New BootRom's with Enable GOP injected and I installed NVIDIA GTX-680's in both with Monterey. I also have them setup with XVF AMD Radeon RX-580's with OC Sonoma OS's if I would like. Of course I have to remove one of my drives and install the RX-580 GPU and a OC Sonoma OS and all is working fine!
