MSI firmware archive covering two board numbers, MS-1454 and MS-14531, both in MSI's own MS-xxxx numbering scheme. No laptop model is named, so identify your unit from the number printed on the motherboard. The two references suggest closely related boards, but the name does not say which variant each image belongs to. Open the archive and match the files to your PCB before programming. Always read and save the original SPI contents first and verify the chip capacity against the image size.
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.
