A duplicate 2.00 MB .bin BIOS dump labelled 635, with no brand, board number or version stated in the name. The capacity matches a 16 Mbit SPI chip. Compare this copy with the other 635 images by checksum to choose a consistent read. Use a hex editor to check model strings before writing. Always save the current chip contents first, because a dump from a different board revision may not boot and the original data holds system identifiers.
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 →
