Hi Justin, I don't know if this helps, but there is work being done to get the X5000 built in network ports working in both AmigaOS and Linux. I know the issue he had/has with the PHY hookups. Honestly, I am not sure which one of you are further along, so I don't know if that helps. I will be installing FreeBSD on my X5000. I will let you know when I get it installed and then I will start testing.
