Firmware archive for a Sony VAIO notebook using the MBX-215 motherboard, with the additional part reference 930-M931 noted in the name. Sony uses its own MBX numbering to identify VAIO mainboards, and that code is printed on the PCB. The 4.79 MB RAR most likely holds a BIOS image for writing the SPI flash with a hardware programmer. Confirm that the MBX number matches your board, dump the original chip for safekeeping, and check that the image size equals the flash capacity.
