Second copy of the CQSO firmware dump, 2.00 MB raw .bin, with (2) marking a duplicate. The name is not descriptive and reveals no board number, revision or BIOS version. Its size matches a 16 Mbit SPI flash chip. Opening both copies in a hex editor or programmer software lets you compare them and spot a corrupted read. Since the source board is uncertain, verify the motherboard number printed on the PCB, save the existing chip contents, and only then write this image.
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.

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 →
