Hi
@rkwallace,
As I too have a Gigabyte Z590I board, I thought to give a helping hand also, so I had a look at your EFI setup and made a number of observations and corrections.
1) First of all I noticed you did not have your Intel UHD 630 IGPU settings set properly. Not having npci=0x2000 in the boot-arg and no IGPU device properties in the PCI device list means the system will not detect your GPUs at all, so I've added those in for you to the config.
2) Incorrect pointer settings, your mouse pointer was set to ASUS under UEFI > Input > PointerSupportMode.
This was probably what gave you the invalid pointer error earlier. It should be empty.
3) Lack of required APCI settings and ACPI/kernel patches. You only had about 3 ACPI tables added when it requires about 14 tables to boot Ventura on the Z590I, so I've added those in for you also.
4) Empty ROM value under Platform Info > Generic ROM. Without a correct ROM value your system cannot boot.
I have temporarlly added 11 22 33 44 66 as the value, but it either needs to be generated.
5) Required drivers, tools and resources folder missing. OpenCanopy was installed but disabled meaning you couldn't use the boot selector properly, and your Tools selection only had CleanNVRAM.efi and no OpenShell.efi either. ResetNVRAM was also missing and is actually the tool you need for proper cache clearing for the EFI, not CleanNVRAM. The Reset function differs from the Clean one.
So anyways I've made all the corrections above for you. The platform is now set to use iMac20,2. Hopefully it should boot Ventura okay.
