Yes, BIOS checked many times.
Oops, just checked again my specifications and it seems i looked a wrong motherboard at Supermicro website.
It seems my motherboard is different :-(
- Intel® 82579LM and 82574L, 2x Gigabit LAN ports.
- 1x Realtek RTL8201N PHY (dedicated IPMI)
So, I need to find out now how to add this second nic [82579LM]
Any one has done this before?
