BIOS archive whose name only reads THERMAL 8-M2L4.5, a code that does not clearly identify a brand, model or board number. It is described as a fully working dump and is 12.4 MB compressed. Without more detail, identify the target hardware by comparing the code against markings on the PCB before use. Such images are written to the SPI flash chip with an external programmer; read and keep the original contents first and confirm the image size matches the chip 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.
