BIOS dump for the MSI notebook motherboard MS-14921, version 1.0, in a 3.07 MB ZIP that wraps a RAR inside. MSI uses MS-14xx board numbers for its laptops, with the last digit marking a variant, so confirm MS-14921 and version 1.0 on the PCB. Extract both layers before use. Write the image to the SPI chip with a programmer to recover a non-booting board, after saving the original contents, and make sure the file size matches the capacity of the installed chip.
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 @bioshub. Enginerys does not host this file.
