Hi and thanks for your answer.
Because I found some other models having the same name, I need to add that the exact version of my network card is this one :
This one is PCI-e x4, not x1 like it is said in the link you provided.
Does it make any difference ?
The more important question is what happens in your O/S environment? Can you install device driver for card and access ports?
I tried to use it on OS Windows 10, Windows 7 and a Unix OS.
On Windows 7 and 10 no more network card is detected in the devices manager and I got no more network device in the network panel.
I managed to install the drivers provided by Intel website with no more luck.
That's why I was wondering first why the device is not detected in BIOS, but I can make a mistake. I don't really know if a device can work fine without being displayed in the BIOS.
So, to be sure that I'm not missing something important, what procedure would you suggest to access a port ?
Thank you for your advice.
It doesn't sound like you are doing anything wrong. Other than verifying that the card works in another PC, I cannot think of anything else to suggest...
