SM_BIOS binary, version 1.0.4.1089, of the 3MB layout and carrying MD, PRD and RGN markers; size is 2.31 MB. No device, manufacturer or board number is given, and the build is close to 1.0.4.1090 in the same series, so compare versions carefully. It appears to be a region image rather than a full SPI dump. A technician would check its structure against a read of the target chip, store that original read safely and confirm offsets before writing, since a misplaced region leaves the unit dead.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
