BIOS image packaged as a RAR for the Sony VAIO M630 and M640, marked unlocked, which usually means the BIOS password or a similar lock has been removed. The 1.05 MB archive should be unpacked and the image size compared with the capacity of the SPI flash on the board, as a mismatched dump will not fit. Read and save the original chip contents with a programmer such as a CH341A before writing. Only use it on the matching model, since a wrong image can leave the laptop dead.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
