BIOS dump labelled thermal 8-m2l4.5, reported as fully working with the Management Engine region cleaned. The name gives no brand, model or board number, so identifying the device it belongs to depends on matching the label against the original chip. A cleaned ME region means the image can be flashed without carrying over machine-specific engine data. The 3.98 MB rar suggests a 4 MB SPI image. Back up the existing chip with a programmer before writing, and confirm the file size matches the flash capacity.
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 @biosarchive. Enginerys does not host this file.
