Michal,
    Looks OK to me. 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.
