From what I had read the linux drivers were fairly similar for the 440x and 570x series. > I couldn't justify the cost of a 4401 eval board to my boss (project > requires GigE), so I have no direct experience with it.

I'll certainly have a look at this, although I haven't had that much experience with device drivers so I won't expect too much :) > For what it's worth, my guess is that the 4401/5702 option on the Asus > boards will soon be replaced by the 5705 as standard. > > Good luck. thanks, - Steve
