Gigabyte z490i ITX / 10900K / Opencore 0.5.9 / Catalina 15.5.5 / Ncase M1

[quicktrick]

Update

So my build is now fully working with no problem at all on Catalina. even Wifi 6 AC 201 is working with bluetooth as well.

Could you share your EFI?

I have the same motherboard using 10600k on 20,1. Has anyone managed to get it working with just the iGPU and no dGPU? If so can you share your efi or plist please. I have it mostly working but if it sleeps it will not wake back up and I get no output on DisplayPort, only hdmi. H265 decoding working fine, FaceTime video and translucency etc. The iGPU and vram pick up on system info.

how about wifi6? Are you still using Heliport or other tricks?

Just a quick question, does anyone managed to get both iGPU and dGPU working at the same time for this Mobo? anything need to change inside config.plist? I'm using Intel® UHD Graphics 630 for iGPU and Rx580 for dGPU.

Yes I have - just posted my High Sierra Z490 guide for the Gigabyte Aorus Xtreme recently.

To get both cards to be recognised - you will need to find out what your CPUID value is from Intel's spec page for your CPU ie. for my Core i5 10400 it is 0x9BC8 > https://ark.intel.com/content/www/u...10400-processor-12m-cache-up-to-4-30-ghz.html

So under Devices\Properties (this is Clover example) you'll need to add the Intel GPU PCIRoot address and properties like this:

and this will allow Intel Quicksync to work. In the above example I'm using 03 for the ig-platform-id because I require the IGPU to work alongside the DGPU, but working as computational-only ie. headless. You can also try 07 or 00 if that doesn't work but you have to enable the IGPU in the BIOS and set PCIE video card as boot device.

For your AMD card, you'll need to test adding darkwake=8 and -disablegfxfirmware in the boot-args, also possibly shikigva=80 or shikigva=128 to the boot-args depending on what kind of decoding you wish to achieve - more about it here > https://dortania.github.io/OpenCore-Post-Install/universal/drm.html#fixing-drm

yes it is wifi6 working file you will have to add it to the driver address list same as the regular lan. get the code from mackintosh tool

I am not using any heliport or anything it is natively supported by AirportItlwm depends what you are using Catalina or big Sur each have a separate driver

Thank you for your reply.

May I know, when using 03 for ig-platform-id, does it mean that I cannot use HDMI or DP from built-in graphic card to display on additional monitor? What does it mean with 07 and 00? I already enable IGPU in the BIOS setting.

As far as I know, 03 is most compatible for your AMD card as it allows for you to use the AMD HDMI as the main GPU output and the Intel GPU as a ‘headless‘ ie. computational unit. For the other two settings 07 and 00 is for Intel GPU output only (afaik).
