Corporate-branch Intel ME 11.8.50.3448 firmware for the H chipset (desktop and high-performance mobile PCH), with the DA tag referring to the supported stepping. Production signed (PRD) and supplied as a stock RGN region of 7.01 MB. Useful when a board shows ME errors, long boot delays or a non-functional ME after a bad flash. Insert it into the ME region of your own BIOS dump with FIT or UEFITool-compatible tools, keep the original descriptor and confirm the board actually uses a corporate H-series ME.
