BIOS backup from an MSI MS-16J9 laptop board, compressed as ZIP. The extra text mentions MSI Thermal and 8-M2L4.5, which are kept as given since the name does not explain them. MSI uses its own MS-xxxx board numbers, and the board printed on your PCB should match MS-16J9 before you flash this backup. It can restore a board after a failed update or a corrupted flash. Read the current chip with an SPI programmer before writing, and make sure the image size matches the chip capacity.
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.
