I have finally managed to locate the official BIOS for the amazing MB10-Datto-O7 from Gigabyte's official support team!

With flashing this bios, does it erase the BMC? I just got 2 s3b1000 with the datto 7 board. I'm fine with the stock bios but trying to get into/resetting the BMC seems impossible without having a datto license/account.
