Firmware archive for the Samsung NP300E5X laptop, covering the Samsung board numbers BA41-01979A, BA41-01978A, BA41-01977A and BA41-01976A. Samsung uses the BA41 prefix for its own mainboard part numbers, and the four variants listed probably differ by CPU or graphics configuration. Match the exact BA41 code on the PCB sticker to the matching image inside. Before writing anything with an SPI programmer, dump and keep the original chip contents, and confirm the image size fits the flash chip on the board.
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.
