Firmware archive labelled ZX-H61C V1.2, 2.25 MB in rar form, with no brand given in the name. The H61 token suggests an Intel H61 chipset desktop board, and V1.2 appears to be the PCB or firmware revision. Such images are commonly used with an SPI programmer to revive boards with corrupted BIOS. Because the manufacturer is unclear, match the board marking exactly before use, read and save the original chip, and confirm the image size equals the installed 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.
