Hi,

As per the thread title, I have an Intel Quad port PCI-E ethernet card that I have just installed, primarily so I can bridge the connections and have 1 in and then the 4 for various outputs (i.e. laptop etc.).

I have installed it into the second PCI-E x16 slot on an ASUS H270-M motherboard, with my graphics card in the first one. Unfortunately Windows 8.1 is not detecting this card, and I cannot see anything in the BIOS that I can adjust or even check that it is detected.

The chip on the card is an Intel 82571GB, which from what I can see isn't supported above Windows 7. Also, could the H270 chipset be a limiting factor? Either way, the fact it isn't listed in device manager makes me think its more of a hardware issue...?
 
Yea it is probably a hardware issue. It is a 13 year old NIC card man lol. It might be due to such an old PCIe version even though they are usually backwords compatible. I know like on Dell they only allow 1 version back. So if it is a PCI 2.0 you are good for 1.0 but for their new ones with PCI 3.0 you can only do 2.0. 1.X devices will not work but usually with these kind of board makers they support all the way back to 1.0

Wow, thanks for the info. I had no idea it was that old!

Perhaps I might have to scrap this idea then.

Sorry for the late reply! Thanks for the information, I can confirm that the card is fine as I tried it in an older system and it works fine.
 


Yea some newer systems with PCIe 3.0 Don't work with PCIe 1.0 devices.

If I set the PCI-E from 3.0 to 2.0, is it likely that this will enable the card to work? It's currently installed in a Dell Vostro tower with PCI-E 2.0 and works perfectly.
