I have been able to update the microcode on the most recent bios for this board.
But that’s as far as I can get. I can’t update any FFS or attempt to add reBar without it throwing an error saying it’s not a valid BIOS file in EZ Flash.
The Bios Flashback doesn’t cooperate either. It will blink 3-5 times then remain solid.
I think my modded BIOS is good to go, but I can’t for the life of me, figure out how to get around the security checks/Aptio V capsule.
I’d prefer not to go the CH341 … I haven’t played with that in a long while.
Does anyone know of a work around, or could point me in the right direction? I’ve been searching for anything on the topic as it relates to this board but it seems like I picked an unpopular one. 
Thank you!,
d.w.
