[Wlug] AIX 5.3 Question

Hello, At work, I have an RS6000 running AIX 5.3. The on-board NIC controller failed. I installed a dual-port Intel Pro 10/100/1000 NIC card. When I start the server, the Intel card isn't recognized. SMIT doesn't see it either. What do I have to do in SMIT so that I can use the card? Thanks, -- -Chuck
