BIOS firmware archive labelled EM SR218 A V3.0, a 3.17 MB RAR whose name gives no brand or full model, only what looks like a board or project code with version 3.0. Because the target device is unclear, verify the code printed on the PCB before use. Such an image is used to restore a corrupted SPI flash chip with a programmer. Read and save the original chip first, compare the size of the extracted file with the chip capacity, and only write once the match is confirmed.
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 @sm_bios. Enginerys does not host this file.
