Collection of BIOS images for the MSI CX480 laptop, offered in three sizes: 2 MB, 4 MB and 8 MB. Separate images usually correspond to different flash chips or to split firmware regions on boards that use more than one SPI device. Pick the file whose size exactly matches the capacity of the chip on your board, since a mismatched image will not fit. Always read and store the original contents with your programmer before writing, and confirm the board version against the label on the PCB.
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.
