Tested working BIOS binary for a J1900 based POS machine board, compressed into a 4.26 MB RAR. The Intel Celeron J1900 is a Bay Trail quad-core SoC widely used in point of sale terminals, thin clients and mini PCs. The manufacturer and board number are not given, so match the dump carefully to the hardware. Flash it to the SPI chip with an external programmer after saving the original contents, and make sure the image size agrees with the chip capacity before writing.
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 @hrtechno. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
