BIOS archive for an MSI board numbered MS-AE321, revision 2.0, with a size of 1.88 MB. The name does not identify the laptop model or the firmware version, so check the contents and any readme after extracting it. Images like this are written to the flash chip with a programmer to recover a board that fails to boot after corruption. Compare the board code and revision printed on the PCB with the file, back up the existing chip contents, and confirm the image size equals the chip capacity.
