'All in one' integrated ethernet driver...

I reformatted my buddies Gateway All-In-One Media Center computer, I believe it's the 610 model, and have been completely unsuccessful in obtaining his ethernet controller driver. I've searched around, tried a few different drivers - but nothing has worked. For some reason, when I search for the 610s ethernet driver, I usually stumble upon wireless drivers but his computer does not have wireless integrated - I know that for a fact. Anyways, I'm wondering if anyone might have had this issue and found a solution or if anyone can just point me in the right direction.
