BIOS and EC firmware for the MSI MS-17591 board, version 1.0, marked as working and fully tested, in a 4.53 MB RAR archive. MS-xxxxx is MSI's own board numbering. Laptops like this keep the system BIOS and embedded controller firmware in separate chips or regions, so both may need restoring after corruption. Write each image with a programmer to the correct chip, check sizes match capacity, and save the original contents before erasing anything.
