BIOS image for the MSI CR420 notebook built on the MS-14531 mainboard, revision 1.2, intended for a 4 MB SPI flash chip and stored in a 1.40 MB ZIP. A dump like this is written with an external programmer such as a CH341A when a laptop will not post after a failed update or corrupted firmware. Read and save the original chip contents first, check that the image size matches the 4 MB flash capacity, and confirm the PCB revision printed on the board corresponds to 1.2 before writing.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
