Firmware archive for the ASUS K50IJ notebook, 590 KB compressed, with no BIOS version or board revision stated. Extract it to see whether it contains a raw chip dump or a vendor update file, since that decides whether it goes through a programmer or the ASUS flash utility. Raw images are written to the SPI flash to revive boards that fail to post. Compare the board revision printed on the PCB, confirm the image size equals the chip capacity and save the original chip contents 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 @biosarchive. Enginerys does not host this file.
