Optiplex 7020 SFF + Intel Quad PCI-E NIC

The spec mentions it is a PCIe2.0 card, 4-lane PCI Express, operable in x4, x8 and x16 slots
This card appears to be designed for Dell server.  Would it be possible that the driver you need can be found in Dell server support (look inside network and intel) https://www.dell.com/support/home/us/en/19/product-support/product/poweredge-r410/drivers

Thanks for replying! The main problem is that the NIC is not showing in the BIOS ( both slots show as empty). What was interesting is that when plugging a network cable in one of the ports ( of the quad NIC) I can see a green light for a few seconds...

I've seen something online about the NIC having to be Microsoft certified in order to be recognized by BIOS.

Could not find any specs on the 7020 : PCI-E version?

That card is a PCI-e card.  Does this tell you a brief summary of its spec?

When I install discrete card I never thought of looking inside bios (I am bios naive). I always look inside device manager in Windows.  If the card is not recognized by bios, two possibilities: your bios is in UEFI mode and secure boot is enabled, for some reason bios blocks the card thinking it is suspicious, or the card is faulty and can not pass firmware test.  To test 1st possibility, turn off secure boot and choose legacy mode of bios, test again.

No I have not had a quad network card, but I find it strange that bios or Windows does not detect a piece of hardware at all.  Not even as an unknown device listed in device manager.  Are you installing the card in the PCIex16 slot of SFF?

Checked BIOS. Here are the settings( didn't have to change, already set): Boot = LEGACY & Secure Boot = DISABLED.

BTW, I also tried disabling on board NIC but without success.

Have you tried a card like this in a Optiplex 3020/7020 / 9020? I won't exclude the possibility of the NIC being bad. I just don't want to buy another one and be in the same situation because .... it just won't work!

To be honest, I've tried both but still without success!

Test the NIC in another desktop to see if it is recognized or detected at all.

Just tried it in another Win 10 desktop and it doesn't show in DEVICE MANAGER. The BIOS doesn't show installed cards so it didn't help.  I plugged an ethernet cable in port 1 and it did light up ( green)...whatever that means... I guess it is not dead-dead...only half-way dead   I guess I needs to try another one.

Thanks!

I begin to wonder whether this particular card is a dud.  how is it possible that it remain completely invisible and totally undetectable as a device plugged in PCIe? The only thing left is to test it in a Dell power edge server.
