Small 421 KB zip holding a BIOS image labelled Z99M AMD, which suggests a board or model designation for an AMD platform, though the name gives no brand, revision or chip details. Treat it cautiously: open the archive, check the image size against the capacity of the flash chip on the board, and compare any identifying strings with the board you are repairing. If it matches, it can be written with an SPI or LPC programmer to recover a dead BIOS. Save the existing chip contents first so the change can be reversed.
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.
