BIOS dump for the MSI CR620 notebook, board MS-1681, meant for a 4 MB SPI flash chip and archived as a 1.46 MB RAR. MSI uses the MS-16xx and MS-17xx style numbers for its laptop mainboards, so the number printed on the PCB is the reliable way to confirm compatibility. The image is used to reprogram a corrupted BIOS chip with a hardware programmer when the laptop powers on without display or restarts continuously. Save the original chip contents first, and verify the file size equals the chip capacity before writing.
