Hello! I have a much better question. Whose GPU are you using? I only know of one specific and that's NVIDIA that is as part of a Video board, there are several out there, who're part of the board itself.

Hi, I'm trying to boot Windows 10 with Coreboot 4.9.2002 using Tianocore + a PCIe GPU and I always get an strange ACPI_BIOS_ERROR.
Without the PCIe GPU, works ok.
I'm pretty sure is an error with my DSDT or the southbridge code. Sadly, I cannot debug Windows to know determine the exact ACPI problem. I also tested with other boards like the Asus Maximus IV GeneZ and the problem is there too: with the IGP only works, but when I attach a PCIe GPU then it crashes.
Take a look to my code if you want, any help about this will be welcome. https://review.coreboot.org/c/coreboot/+/33328
Thanks.
