PFSense installed on Sophos SG125 v3 new PCIe NIC's not Detected

[Yoe777]

I have PFSense installed on Sophos SG125 v3 which has worked amazingly. This hardware is very similar to a Nexcom DNA 1160 only it has a Mini PCIE port and a PCIE x4 port. I am attempting to take advantage of the additional PCIE ports to add more LAN capability.

I have purchased a Mini PCIE to PCIe x16 and a PCIE x4 to PCIE x16 adapter. I then in turn have attempted to install 2 checkpoint LAN controllers (PCIe Gen2 Intel 82580EB based that support FreeBSD). After booting up PFSense with these installed they are not detected. I ran "Shell Output - pciconf -lv | grep -A 3 -E "^none"" and see that the system does not see the cards at all. Checking BIOS settings both of the PCIE slots are enabled.

Any ideas on what the failure point is or what I can try?

Thanks in advance.

Can you see them in the BIOS POST output?

I would try the card in the PCIe slot only first.

Do you have a PCIe 1,2 or 4x card you can try in the slot directly?

Do you have a mPCIe card you can test dircetly? A wifi device maybe.
