Copy of a K52Jr firmware image, an ASUS laptop model, 4 MB in binary format and sharing its name with another file in the index. A hex comparison with the duplicate will show whether it comes from a different source or is identical. Images like this are written to the SPI flash with an external programmer such as a CH341A to recover boards stuck on startup. Read and keep the current chip contents first, confirm the chip size equals 4 MB, and verify the motherboard revision against the dump source.
