PCI LAN card not detected on Sierra GA Z87X OC

[digiman]

Hi friends,
I have freshly installed Sierra 10.12.14 using UniBeast, on the Gigabyte GA Z87X OC mobo.
As the onboard LAN port had failed, I installed a PCI LAN (Realtek chipset) card.
I installed the network drivers/kexts for Realtek, using Sierra Multibeast 9.2.1.
On checking System Information, PCI cards, the card is not detected-
This computer doesn't contain any PCI cards or devices. If you installed or connected, a PCI card or device, make sure they’re properly installed.
I had deselected the onboard LAN option in BIOS.

All inputs towards a solution is highly appreciated. Thanks for your time.
