Hi SenK,
If you are using the UEFI Payload you need to ensure that:
1. Your payload DSC file contains "MdeModulePkg/Bus/Pci/NvmExpressDxe/NvmExpressDxe.inf" in the [Components.<your_ARCH>] section (where <your_ARCH> is one from X64 or IA32). 2. Your payload FDF file contains "INF MdeModulePkg/Bus/Pci/NvmExpressDxe/NvmExpressDxe.inf" in [FV.DXEFV] section
Yes, the NVMe disk should be detected during PCI enumeration in coreboot. If it does, that means you lack the above in your UEFI payload. Otherwise there is something wrong in your coreboot port.
Best regards,
