Small ZIP archive, 1.37 MB, holding Intel PMC firmware, the Power Management Controller code that sits inside the flash image on newer Intel chipsets. The file name lists no platform, version or board, so the contents need checking to see which chipset generations are covered. Such files are used when rebuilding a full SPI image with Intel tools, where a mismatched or missing PMC module can prevent power-on. Confirm the PMC version fits the chipset and ME firmware, and back up the existing chip before any write.
