Backup firmware labeled H61M-A REV 1.02 HEATSINK, an 864 KB RAR archive with no brand given. The meaning of heatsink here is unclear, possibly a board variant or a note from whoever made the dump. The size is small for an 8 MB image, so check what the archive holds before use. A backup like this is written to the SPI flash with a programmer to recover a board with a bad BIOS. Match the board revision, back up the current chip and confirm the size fits the chip.
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.
