Why is this happening. I recently upgraded my hardware and moved from Core to Scale. I now have spare hardware and I am installing Scale. The typical process …
I did see that in my googling about the freeze and some of the messages I can see. The answers I see are to insert an option into ??? … but … how do I get to the code if I can’t get it to boot?
There’s nothing especially unusual about your motherboard, so it’s very likely to be a BIOS setting, or possible something weird going on with your boot device.
I don’t understand why it wouldn’t boot just because the network cable wasn’t connected.
You certainly wouldn’t be able to connect to it from a client computer, but TrueNAS should still boot to the Console menu (and there let you know it couldn’t acquire an IP).
