Copy-suffixed 16.0 MB BIOS dump for the 2570P, also tagged Q128, which probably refers to a 128-Mbit SPI flash matching the file size. It sits beside a same-named file, so compare the two by checksum before deciding which to program. No board number, revision or version appears in the name. Flash it with an external programmer and clip only after saving the current chip contents, and check that the flash part on the board really is 16 MB.
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 @biosfilebins. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
