Working BIOS for an MSI-related Casper A15HC laptop board, revision 2.0, described as the version with the Nvidia GPU as main graphics, packed in a 2.48 MB RAR. Using the right graphics variant matters, since a mismatched image can leave a blank screen or disable the discrete GPU. Write it to the SPI flash with a programmer after saving the original dump. Compare the board revision on the PCB with 2.0 and confirm the file size matches the chip capacity before flashing.
