Fix/workaround for Gigabyte keyboard 

The gigabyte keyboard has an N key rollover input, that is different than all of our current keyboards.

So this code tells (currently All) keyboards to choose their boot protocol, which gets us back to the standard boot definition.  Which alllows these keyboards to function like others.
