At this point I don't know what's causing your issue. And it's likely that if you switched those NICs into a more modern server (the Z200 is quite old at this stage), it's likely that everything would just work. All I can suggest at this stage is to maybe get your hands on a PCIe x1 GFX card to free up the x16 slot, and try using the gen2 x16 and the x4 for the NICs. Dave.
