Damn I'm sorry. I'm kinda swimming into new waters here, been using windows a long time. It took me an embarrassingly long time just to figure out how to reflash them in the first place.
I flashed to the latest version and I get the same issues. Whatever raid card is in my bottom PCIE slot will not work in unraid. My top one works fine. Either card in the bottom one doesn't work. I would figure a bad pci-e slot, but the motherboard is fairly new, and the option rom, motherboard bios, free nas, and windows are all showing drives from both, top and bottom. Also, when I don't have the top one plugged in...the bottom one works fine in unraid.
I'm at a loss. I had 15 drives I wanted to use, so I need both cards. I could RMA my motherboard...but everything seems to work except in unraid. Anything else I can try?
Edit: Tried unraid 6.3.5, same thing.
