BIOS for the MSI CX420 notebook on mainboard MS-14531, which follows MSI's MS-xxxxx laptop numbering where the 14 prefix indicates a 14-inch class board. The RAR archive is 1.47 MB. A dump like this helps when the laptop powers on with no image or loops after a failed update, and is written to the SPI BIOS chip with a programmer. Check that MS-14531 and its version on the PCB match, save the original chip read, and confirm the image fits the flash capacity.
