Firmware dump for the Samsung NP940X5M notebook with main board BA41-02591A, packed as a 5.69 MB RAR. Samsung uses the BA41 prefix for its own motherboard part numbers, so the code on the PCB should match before writing. Technicians program the SPI flash with an external programmer to recover units that will not boot after corrupted firmware. Read and archive the original chip contents first, since serial and configuration data may be stored there, and compare the image size with the chip capacity to avoid a mismatch.
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.
