I tried different options in config.plist file. Finally, I was able to boot the system using OC (the first time of successful boot, yeah). What did I make to achieve it? Totally removed PciRoot(0x0)/Pci(0x2,0x0) section from the originals you and
@ModMike posted. Unfortunately, all the OS animations were lagging with OC boot as well. Even more, when I tried to inject the device and platform ids from your shared folder to my permanent Clover EFI folder, I got the same failed booting results.
It looks like a good trend because all the issues I have now are around the
I5-9600K (UHD 630) processor. I tried to inject many combinations of devices/platforms but nothing of them helped me. BS animations were slow, HDMI monitor was failed to awake from sleep properly.
I wanted to report a bug for whatevergreen team but they don't provide supporting and the 'Issues' tab is closed on their GitHub page.
Any idea then of what can be done to get my iGPU working correctly?
Thanks, everyone.
