I had patched the BIOS image from Supermicro for my motherboard and flashed my own modified BIOS to my X10DAi mobo. It was largely cosmetic (replaced the Supermicro logo with the Apple boot image, restored some stuff that had been removed from the EFI shell, etc.)....but more importantly, I couldn't patch the bios so that it leaves MSR 0xE2 unlocked. Motherboards often lock this register, and that prevents macOS from booting. So I need help to MSR 0xE2 to be unlocked.
