PEX8112 x1 Lane PCI Express-to-PCI Bridge (rev aa)" as a bridge to communicate with the motherboard. And THIS component isn't supported! No, that wouldn't matter. Bridges are fairly standard. It would be helpful to get pciconf -l output so we could see the actual device and vendor ID register values. -- John Baldwin
