BIOS image that converts a DNS a17hc notebook to the Medion E7220 firmware, version 303, with the Management Engine region cleaned. A cleaned ME region removes stored configuration so the engine reinitialises, which helps avoid boot or shutdown problems after transplanting firmware. The ZIP is meant for an SPI programmer rather than an in-OS update. Because it is a cross-brand conversion, confirm the boards really share the same design, and store the original dump before writing.
