Firmware dump for an ETON ET856 board, RAR of about 3.96 MB. The other tokens, 94V-0 and E213441, are PCB flammability and UL certification markings rather than a model or revision, so the name says little about the actual device. Use the ET856 code printed on the board to confirm a match before flashing. Read and keep the original SPI chip contents, check the image size against the chip capacity, and then write it with a programmer.
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 @biosarchive. Enginerys does not host this file.
