I have used these boards(I have 6 of the same motherboard) for about 3
years now with no problems, until I upgraded the OS this summer from
Fedora Core 4 to CentOS 5.  With every windows install and Linux
install on these mother boards they report two separate nics that can
both be configured and active at the same time with the same MAC
address.
