Hey look at that! A bunch of numbers! Hopefully they mean more to you than they do to me...

No worries - once I can get a reliable install, I hope to never need to touch those again anyways. I mostly am hoping to get eMMC so I can flash updated firmware, assuming the errata list is correct and my silicon rev CAN boot from firmware on eMMC and it was a layer 8 failure.

I can't find the PCIe cables for my PSU right now, so the RX480 is out until I have time to dig through The Cable Box Of Doom. But I do have a spare LSI SAS HBA that I'll try after lunch!
