BIOS archive for MSI motherboard MS-14921, version 1.0, delivered as a zip that wraps a RAR file, so it needs extracting twice. MSI numbers its own notebook boards with the MS- prefix, and the extra digit after MS-1492 identifies a particular variant, so check the code on your PCB carefully. Technicians use such a dump to reprogram the SPI flash chip with an external programmer when a board is dead or stuck. Save the original chip first and confirm the image size equals the chip capacity.
