Problems with Installing Catalina

[jthunternz]

Hi,
I've been trying to install Catalina. I can get to the OpenCore menu, and select MacOS but it doesn't make it any further.
my config.plist works on the Checker

Attached a zip of my EFI and a log file below.

Hope someone can help!

BIOS SETTINGS
Fast Boot = Disabled
CSM = Disabled
4G Encoding = Enabled

Thanks for the quick reply! I tried your config unfortunately didn't work for me. Could it be a problem with the MacOS partitions on the USB?

Possibly. Try to recreate the USB.

Okay I have made considerable progress since my last visit, I can make it to the MacOS installer now but my page is just a big artifact really.
I have tried unplugging my other display and even switching from DP1.2 to HDMI to test but no success. I'll boot windows up and post my boot args from the config.plist

I have also tried recreating the USB twice now and tried 2 other versions of the OS from gibMacOs.

BOOT ARGS
" -v keepsyms=1 debug=0x100 agdpmod=pikera "

SMBIOS is MacPro7,1


UPDATE:
SOLVED!
Although I had above 4G decoding enabled in my BIOS I still had to include the boot argument that it explicitly tells you not to use if 4G decoding is enabled.
