BIOS image archive labelled only H61-MX, about 2.61 MB, with no brand, revision or board code given, so the exact board it came from cannot be determined from the name. Generic H61-MX boards were sold by several vendors, so the dump should be matched to the board's sticker and Super I/O chip before use. Technicians use such files to recover a dead or bricked board by programming the SPI flash externally. Always back up the original chip and confirm that the image size fits 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.
