Intel CSME 15.0.35.2039 in its Corporate variant for the PCH-H chipset at B stepping, a production image extracted from a working system, with an -Y suffix that is not expanded here. The 15.0 branch is the Tiger Lake generation, and H chipsets usually appear in higher-performance laptops. At 9.89 MB it is an ME region only.
