BIOS dump with the Management Engine region cleared, labelled T450, in a 5.75 MB RAR archive; no brand is given, though T450 is a model name used by Lenovo ThinkPad, so confirm the machine before use. The name offers no board number or BIOS version. Technicians program images like this onto the SPI chip with a hardware programmer to fix ME faults or corrupted firmware. Always back up the original chip first, compare the board number printed on your PCB, and check the image 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.
