Building a new system with Asus Crosshair VIII and 3900x.  Updated BIOS to 1105.


Board runs through the internal diagnostics and hangs right before where it should be entering BIOS with an error:


"AP initialization before microcode loading"


Would this be an issue in the CPU or MB?   Where is the microcode loaded from?  Internal to CPU or BIOS?
