I have a fairly closely related question, and I’m guessing it may be better to ask it here rather than start a new topic.
TL; DR: Where can I find the correct as-shipped BIOS settings (not the BIOS firmware?)
Details:
I have a Mini X, bought in late 2020, built and shipped in early 2021. S/N A1-84971
Due to a recent tropical storm where we expected to get one or more power outages (and did!) last weekend I had powered down my Mini and disconnected it and its UPS from mains power to avoid damage due to voltage spikes.
On reconnecting it this week after everything was back to normal, it did not come back up as normal. For a while it was seeming it would not power up boot at all and seemed to be behaving erratically - nothing on the monitor - but after moving it, opening it up, and checking it, I got it to at least boot into the BIOS. (It was a pain finding a VGA monitor, but I’m enough of a packrat that I found one.) I suspect it lost its NVRAM settings due to the lithium battery being dead and the system unplugged for at least 5 days before I was ready to set it up again. For one thing, the system date/time was about 5 days off. (It was showing 8/18/2026 today, when it was 8/24/2026 in UTC TZ.) For another, SMART support showed as disabled which seems wrong.
I’ve replaced the CR 2032 battery, and want to make sure the settings are correct, before I boot it fully back up. I could try to go by gut on the settings, and was starting to set them but then thought better of it. I’d like to be able to verify they’re correct before restarting the system and avoid messing up something which might be critical to operation.
I looked at the Mini X+ OOBM setup guide, which only covers IPMI setup (and is a later model anyway) and I checked the TrueNAS Mini docs hub but didn’t see anything on restoring the basic BIOS settings.
Is there any guide or reference to correct BIOS settings available for this earlier version? Screenshots?
