ZIP archive of 573 KB for the MSI board MS-7525, following MSI's MS-xxxx numbering used on its desktop motherboards. The name does not say what is inside, so check the contents after extraction; a file this size commonly holds a BIOS image. The MS number is printed on the PCB and must match before flashing. Read and save the original SPI chip with a programmer first, and confirm the image size fits the chip so a mismatched or truncated dump is not written.
