BIOS for the Samsung NP-R525, configuration JS03RU, Samsung board BA41-01196A. The archive is small and the name does not say whether it has been tested. Samsung uses BA41 numbers for its motherboards, and the matching schematic may carry a neighbouring number, so check the label on the PCB. A technician writes the image to the SPI flash with a programmer to fix firmware corruption. Back up the original chip first and make sure the image size equals the chip capacity.
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.
