Note
1. The PCI Express Ports are visible only if they are set to "Enabled" in the BIOS setup program and a device attached to the corresponding
PCI Express port on the carrier board.
2. The above table represents a case when a single function PCI Express device is connected to all possible slots on the carrier board. The
given bus numbers will change based on the actual configuration of the hardware.
