Regardless of whether or not there is a manufacturer around, it is vital to remember this: Don't test haphazardly. Bill Lin cautions, "Never test without proper preparation." If data has not been properly backed up first and testing goes ahead, the originally installed parameters in the chips could be wiped out, and at that point there would be no going back.
