Question: Can you run this card and the onboard ethernet or does it cancel out the onboard ethernet?
Document: If you have a gigabite router, you need a gigabite card. My on board Intel 10/100, did not interfere with this install. Was a breeze. Bob...UPDATE 10/22..Inrel onboard was still set to run. Did not interfere with gigabite card, but I went into bios and turned it off, rebooted, everything fine.
Linux allows a single NIC to handle multiple IP Addresses, but that left me with an Ethernet collision domain that overlapped IP Subnets. That works, but not without occasional complaints. The Linux CentOS that I run gives me relatively powerful tools to route and firewall a subnet.I went looking for an inexpensive NIC that I could install on a open slot in my server, preferably a PCI Express x1 slot. I strongly preferred a gigabit NIC to speed up network backups.
A recent storm fried a couple ethernet ports and cards at my church including the onboard ethernet in a Dell Vostro 460. Unfortunately, the 460 only has PCI-E slots and our stash of PCI ethernet cards was useless.The Intel Gb PCI-E was a great, cost effective solution for us. I disabled the dead onboard ethernet and installed this in a free PCI-E slot and was back on the network in minutes.
I turned an old PC into a Windows Home Server 2011, which is based on Windows 2008 R2. Because all the newer PCs around the house have gigabit cards, I thought it was time to upgrade. The Intel card was recognized without the need to get drivers from the Internet. Our backup and file copies run much faster now.
What can I say. It's an Intel ethernet card that works well for around $30 bucks. That is what I was looking for.
this ethernet card works with VMware esxi v5.5. Add 16-32G of memory and you will have a good home lab machine.
Upgraded my system and needed a gigabit ethernet card  also . Decided on this one because of the Intel name and the price . Works great and my speed has improved
I just needed a new ethernet card as mine went bad. Very simple plug and play and worked from the start no need to install any drivers! !
The ethernet port on my HP desktop died. No idea why. Could not find a PCI-E ethernet card at the local office stores. This one works great under Ubuntu and Windows.
Really, not much I can say about this other than... it works! The ethernet port on my motherboard wasn't working, I popped in this card, now I have working ethernet. Easy to install, no real config required, and the price was right.
Answer: It depends on the Operating system you are using. Some OS (mainly those designed to facilitate networking Win 7 Pro, ultimate, etc) will allow you to configure and run both at the same time
