I came=20= up with a Wikipedia article that was positive. I also decided to look back=20= at the specs listed on the Tiger Direct site where I got the interface cards=20 and there it was, pretty plain. Compatible with x1, x4, x8, and x16 full-height and low-profile PCI=20 Express slots There is still a problem. One of the cards is initializing and the other is not. I have not determined which one is not. But the punch=20= line is that the one that does show up shows up with status no carrier in=20 ifconfig. I looked back the the FreeBSD site, at hardware notes for v6.2 and it=20 appears that that card specifically, is not listed as supported. 82572 is=20 listed as supported by the em driver, but Intel=AE 82572EI or Intel=AE 82572GI Gigabit=20 Controller is not listed specifically, Well that is another $70+ not well enough spent. thanks for the response. I guess I will try the driver source route=20 from another message from this list, for the Marvell interfaces. I will have to burn=20= it to a cd and install from that. Jeff K
