Corporate Intel CSME firmware, build 15.0.41.2158, for LP mobile chipsets at stepping B, production extracted, with a -Y suffix that is not explained. The larger 7.27 MB size is typical of Corporate builds, which carry extra AMT features. Do not substitute it for a Consumer image on a board that originally shipped with Consumer ME. Inspect the file with ME Analyzer, merge it into the ME region of a full SPI dump, and keep an untouched backup of the chip before programming.
