BIOS and EC firmware package for the MSI GL75 9SD gaming laptop on board MS-17E51, MSI's own numbering for this design. Having both the main BIOS and the embedded controller firmware lets a technician restore either chip when the laptop is dead, does not charge or fails to power on after a bad update. Both images are written with an SPI programmer or the appropriate tool for the EC. Read and keep the original contents before flashing, check that the board number on the PCB matches, and confirm each image size fits its target chip.
