https://review.coreboot.org/#/c/28380/7//COMMIT_MSG@41 PS7, Line 41: - VGA ROM for Nvidia GPU is not loaded from BIOS (i.e. coreboot). Need
Should work with pciXXXX,YYYY.rom in CBFS. […]
I think I know why it doesn't work. PCI ID of my dGPU is 10de:0ffc, which can be checked with `lspci -nn`. But the ROM I extracted from vendor UEFI dump is for 10de:0ffb, which can be checked with `romheaders` and there's also "ID mismatch: vendor ID 10de, device ID 0ffb" error line in cbmem. I'll try to edit the device ID in the ROM image.
