BIOS and EC firmware for the MSI PS42 8RB laptop, board MS-14B1 version 1.0, supplied in a 4.14 MB RAR. MSI designs its own boards, and the MS-xxxx code printed on the PCB identifies the platform. The archive is meant for reflashing the system SPI chip and the embedded controller when the notebook has no power, no backlight or a corrupted firmware. Read and save the original chip contents first, and verify the board number and version on the PCB 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.
