I am having issues with my 740xd recognizing my intel x520 10gb pcie card as a network interface.  When I go under System > PCIe slots, it shows the slot as populated with a "82599 10 Gigabit TN Network Connection" intel 8 lanes gen 3 but no part or serial number and says health status Ok. Under Hardware Inventory, it shows all the info as well. It is in a PCIe gen 3 x16 slot so wondering if that has any affect being a x8 card but I wouldn't think it should. When I go under System > Network Devices it only shows the Integrated NIC 1 QLogic 577xx/578xx 10 Gb Ethernet BCM57800 but not the intel pcie nic. So under LifeCycle Controller > System Setup I see the Intel x520-t2 adapter show up with the MAC address populated, but when I try to click on it, it just exits the system setup screen back to the main lifecycle controller menu screen. So I tried to update the driver for x520 via usb but get this error message "Unable to complete the firmware update operation because the specified firmware image is for a component that is not in the target system inventory." What am I missing here?  
740XD not properly recognizing PCIe intel NIC 10gbe card
