It does show up in lspci. This is the output of lspci -tv. The SATA card is about 4 down. The network is about 6 down. -[0000:00]-+-00.0 Advanced Micro Devices, Inc.

When I try to start the network, it says: ERROR: Interface enp3s0 does not exist. Ensure that you have loaded the correct kernel module for your hardware. I find that odd since it obviously sees the card. It's in the list above after all. So, it sees the card but can't see it. 0_o Odd. I tried different slots for the SATA card and they all do the same thing. Wouldn't each slot have a different interrupt? It's been ages since I had to deal with any of that. Mostly it was on IDE drives and the master/slave thing. Oh, the other odd thing, it sees drives connected to the SATA card as well. It was at this point, I checked your suggestion. I looked and noticed that the network card was now at slot 4 not slot 3 like it used to be. So, I created a new link to slot 4. The network came up. So, basically, it changed names as you suggested. I thought the purpose of the enp* names was that they are consistent. Adding or removing cards wouldn't change the names of cards, like network cards. It seems, in this case at least, the names can change. Any way to make adding the card not change this?? I tend to not have a monitor or keyboard connected to this rig. This is great tho. I now have one extra SATA card already here. Another that I ordered a couple weeks ago that is still on the way. I also have two more from Amazon on the way. Two 10 port cards, two 8 port ones. That's 36 drives. I think I'm all stocked up on SATA cards now. I need more hard drives, still. According to du, I have 67TBs of data here not including backups. 0_0 We got it all working. It never occurred to me that the slot number would change. Still, I need to figure out how to make the network come up whether the card is installed or not. Me thinks. Thanks for the tip. It certainly helped. I wasn't expecting that to change. Dale :-) :-)
