MSI firmware dump for the MS-1452 laptop, with the mainboard identified as MS-14521, labelled by its source as a fully working BIOS. The RAR archive is small at 854 KB, so check the contents and the actual image size against the capacity of the SPI flash chip on the board before writing anything. MSI numbers its notebook boards in this MS-xxxxx pattern, with the extra digit marking the board version. Read and save the original chip contents with a programmer such as a CH341A first, then reflash and verify the written data.
