SM_BIOS binary at version 1.0.7.1133, labelled 3MB and carrying MD, PRD and RGN tags; no brand, model or board number appears in the name. The 2.31 MB size does not equal a common SPI capacity, which points to a region image rather than a complete dump. A technician would compare it with other builds of the same series and with a read of the target chip before deciding where it fits. Save the current firmware first and verify offsets carefully, because writing a region image at the wrong place will leave the device unbootable.

How to open a .bin 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 →
