Re: what exactly is enc0?
The board's PCI slot has to be molded to support it. If not, a dremmel and a little precision will permit the card to sit in the slot with no problems. Shave a few mm off the PCI slot's side, don't cut the card. . On 10/16/08, J.C.

enc0 is a virtual interface for ipsec traffic. See the enc(4) man page for details.

Re: what exactly is enc0?
ok enc0 is actually a virtual interface. It's not even that other network card. The other network card that's not being detected is part of the bellerophon PCI daughterboard which includes a video out, ethernet, sound card, a red led that's always blinking, among other things. Apparently, openbsd is not detecting this PCI interface. If anyone had a similar setup, help would be appreciated. Otherwise, I can just go ahead and get two Sun PCI Network Cards.

Re: what exactly is enc0?
Can you put the regular smaller PCI cards (The majority of PCI cards) in Suns? The Sun PCI port is bigger, but can smaller PCI cards fit into these bigger ports?

Are you sure they can fit in the slots? Wikipedia shows two voltage types for PCI cards: 3.3V and 5V which have different configurations. Regular 32-bit PCI network cards use 5 V signaling, which is what more computers have. I'll have to check and see what the Blades have. They may be able to support both types. Thanks.

Re: what exactly is enc0?
The network card(s) I have in bulk are the Encore Gigabit (9.99) from Newegg. I checked out that these were indeed Universal 32-bit, so it's definite that they'll fit in the Sun Blades. I just wanted to install these for the CARP/pfsync interface. I just started freaking out before because I had some old PCI sound card which was just 5V and then after looking at the Sun Manual to see that the majority of the slots are 3.3V. In either case, the cards should work. Great! Thank god for Universal PCI!!
