Hi, I installed Coreboot with SeaBIOS on a Supermicro X11SSH-LN4F. The stock BIOS can read two NVMe drives in a Dual m.2 splitter card inserted in the middle slot 5 on the motherboard. But coreboot can not. In the coreboot nconfig menu there is no setting that will enable bifurcation of the x8 slot to x4x4.
Is this something that is configurable in any way?
