MP 7,1 OpenCore on Mac Pro 7,1

So with Secure Boot disabled I do get to the normal Verbose output, but I get the IOBCC Panic as seen here:

Attached debug log also!

Quick update, I am having a wild time trying to get rEFInd setup... I have gotten it to boot once only and without icons but it only showed Mac as a Legacy OS... I will continue 😅
 
Copy this BOOT folder inside your EFI folder. If you have Microsoft BOOTx64.efi in your original folder back it up.

Okay, I added this to my EFI on my USB stick. This booted only to a grey screen... I have to be doing something wrong here. The folder I have it in would be /Volumes/EFI/EFI/BOOT, which is right I think. Maybe there is something up with my Mac?
 
Delete BOOTx64.efi, copy/paste (command+C/command+V) refind.efi and rename the refind.efi copy to BOOTx64.efi and try again.

Okay, tried it on both my actual boot drive, as well as 2 USB drives with the same experience on all three. Grey screen only with the BOOT you sent me, black screen when I rename the refind.efi to BOOTx64.efi. I also reset my PRAM to make sure that wasn't it, but no difference. Gonna see if there is a firmware update for my Mac or something.

Yes check for update. Normally that comes automatically with the operating system, but you can try manually providing you don't have the latest firmware like this:

Extract Firmware from OS X installer

Also when you reset NVRAM, Startup Security Utility will reset too, so you will have to enable external boot again.

Alright, good news! After updating to 11.2.1, rEFInd works now without issues! I wonder if OpenCore would now work...
 
No difference unfortunately, but I feel more confident now. I am guessing we arent going to get OpenCore to boot with AppleSecureBoot on, but surely it cant be impossible to get past the IOBCC panic...
 
If you have a debug OC version the log should be in the EFI folder. Try this.

@startergo Yes, I was able to boot Big Sur from Preboot from rEFInd! If this would help me to disable the Nvidia card, and I can flip the drives I want to Internal with Innie, then we may have a solution!
 
Try this config. @vit9696 said if rEFInd boots there is an error in the config.

Code: 
<key>DisableIoMapper</key>
            <false/>
<key>EnableJumpstart</key>
            <false/>
These are the last changes.

So, I had DisableIoMapper enabled as prior to the Firmware Upgrade I was getting a vt-d hang and that seemed to resolve it. I guess at this point whatever was going on before was just a mess.

I tried adding my SSDT for the GPU disable but its landing me in an apfs_keybag_error or something like that, but I didn't really have time today to dig much further on it. When you disabled your Nvidia card, did it disappear from the Graphics section of System Info?

Thank you again for all your help. You really have been awesome!
 
@startergo My apologies, been a busy couple of days! I did use that guide, and from the Windows side it appears my path is _SB_.PC03.BR3A. So in saying that, I modified the SSDT to this which I believe is correct:

    }
}

I will double check it though as I suppose it is probably wrong :p
