I have the same problem with my Shuttle SB86i, which has the Marvell 88E8053 gig ethernet card. I simply can't get this thing to connect!
I've tried FC4 but with no success, so last week I got Fedora Core 5...but still nothing.
I'm a real Linux newbie, and I mostly bought this PC just so I could learn and tinker without any fear of destroying important data. So...I really have no clue what to do next.
Help is greatly appreciated!!
