@erik3452002, despite having been asked almost 2 weeks ago, you haven't provided full system specs. I think the most likely cause of your problem, as I said earlier, is either an outright incompatibility or a BIOS problem--but since you still haven't said what motherboard and CPU you have, there's no way anyone here can tell if this is the case. Even with what we do know, though,
- You're using an AMD processor, which is known to be problematic with FreeBSD,
- You're using 1/4 of the minimum system requirements for RAM,
- You're using an old system (old enough to use DDR2 RAM), which is unlikely to have adequate performance,
- Your old system is highly unlikely to support ECC, which is pretty much essential if you truly want secure storage, and
- FreeNAS simply can't work using a single device for both the OS and data storage.
If you need to use this machine as a NAS, you really need to do it with different software--FreeNAS just isn't designed to do what you're wanting to do (or anything else, really) with this hardware. If you'll devote appropriate hardware to it and RTFM, you'll do well. If you're looking for validation that, despite falling fall below the stated hardware requirements, your system will be fine, I'm afraid you won't find it here.
