Thanks for the info! Now I just need to figure out if xpress recovery/save bios to hdd is diabled by default. My MA786GM-US2H has it disabled by default so I imagine this board should have it disabled by default as well.
If someone could help take a look in the bios, this option should be under Advance settings, "backup bios to hdd: enabled/disabled"
I'd like to purchase this board to be used with unRaid but not if HPA is enabled by default.
