Problem with : default gateway, 2nd NIC

2nd NIC use TP-Link TG-3468 Rev 1.2. Based on this site http://www.microbarn.com/details.aspx?rid=102333, this NIC used chipset Realtek RTL8168B, same with the 1st NIC or onboard NIC. The problem is, why the CentOS doesn't recognize it? It's cause by hardware or OS? The chipset can see on NIC board, one of the ICs. Onfortuately, I can not see the MAC Address on NIC.
