Hi Thank you. I flashed the OEM firmware back on to the chip, tried the bifurcation card with two NVMe drives, and dumped lspci oputput to file. There is a setting in the UEFI setup where you can set PCI-e SLOT5 Bifurcation to "Auto" or x4x4.
Hi, please reply to mailing list too.
I left out the complete lspci you sent, but attached here is the relevant section. It is PCI 0:1.1 and 0:1.2 that require different configuration from what stock coreboot now does.
I think the patch I sent previously has a fair likelihood of working. Auto-detection or a choice in menuconfig is something that can come later.

Hi, Sorry, my mistake. I built a new coreboot binary with the patch you suggested and tested the same configuration as the OEM firmware. SeaBIOS could not detect any of the drives this time.
Unfortunatley I have only two NVMe drives and one is my boot drive so the lspci dump is with only one NVMe in the splitter card. In the lspci output there now PCI 0:1.1 and 0:1.2 is missing. I attach the full output file. Is there anything I can test or do you have any hint on where I can proceed from here?
