A 2.31 MB production firmware region, version 1.0.0.1055, marked 3MB, MD, PRD and RGN. It is one of several neighbouring builds in this series, useful when a specific older revision is needed to match a platform. The name gives no model or motherboard number, so suitability must be judged from the version line and the platform. Region images like this are normally integrated into a full flash image with a firmware editing tool, never written raw to the chip. Dump and archive the original SPI contents before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @sm_intel_repository. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
