Raw BIOS image of 16.0 MB named X61.BIN, with no brand, board number or version beyond the X61 label, so its origin should be verified before use. The size corresponds to a 128 Mbit SPI flash chip, and it will not fit a smaller one. Open it in a hex editor or UEFI tool to check strings identifying the board. Before programming it with a CH341A or similar tool, read and save the original chip contents so the board can be restored if the image proves unsuitable.
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 @ITHINKHS. Enginerys does not host this file.
