System BIOS for the MSI CX480 notebook, board MS-14Y1, intended for a 4MB flash chip. MSI designs its own boards, and the MS-xxxx number on the PCB identifies the platform. Such an image is used to reprogram the SPI chip with an external programmer when the laptop fails to post or after a failed update. Before writing, read and save the existing contents, confirm the MS-14Y1 marking on the board, and check that the chip is really 4MB so the image fits and verifies correctly.
