So I followed the guide below and have an issue. The ex475 reboots after "Verifying DMI Data Pool" during POST.

In my attempt to troubleshoot the issue, I wiped my BIOS backup. Rather then make things worse I am asking for guidance.

So sorry to hear your bios hack did not go well.
Sounds like you need someone that can send you a copy of the factory bios. I do not have the 470 anymore so am no help.
Good luck worse case is finding a used one on ebay and at least you will have spare parts.
Good Luck
