Firmware binary labelled H61MXP, 4.00 MB, presumably for an H61-chipset desktop board, although the name gives no brand or revision. The size matches a 32 Mbit SPI flash chip common on boards of that generation. Use it to reprogram the BIOS chip with an external programmer when a board will not post. As the source is unclear, compare the model string inside the image with the board silkscreen, keep a backup of the original chip, and verify the written data afterwards.
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 @laptopdesktopbiosbin. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
