Nothing happened, same "error" as in, no LAN activity at all. I can't even install Debian or Windows 10 because it hangs up after 2 seconds when it boots into the installer. I also have to wait 2-3 minutes and press F11 or DEL over a hundred times to get somewhere every time I reboot the system. This is ridiculous.
And I have no idea why I'm seeing so many options in the boot menu, I've either bought a broken motherboard or this is just a thing for all Supermicro products. I've quite literally disabled everything except for "USB Hard disk" and "Hard disk" in the boot menu, yet, I'm seeing all of these options every time.
Edit: Did you buy this board second-hand? Are you able to return it?
Second-hand. Not sure, I can just chargeback because there was no mention of dead LAN ports in the description, but I don't think it is dead... I think it's just Supermicro itself being bad.
