● The B/D/F (Bus/Device/Function Number) values are the default values when
the server is fully configured with PCIe devices. The values may vary if the
server is not fully configured with PCIe devices or if a PCIe card with a PCI
bridge is configured.
● The PCIe x16 slots are backward compatible with PCIe x8, PCIe x4, and PCIe
x1 cards. The PCIe cards are not forward compatible. That is, the PCIe slot
width cannot be smaller than the PCIe card link width.
