Sony VAIO VPCY216FX BIOS firmware stored in a 1.61 MB RAR archive, tied to the Sony model code MBX-229 and the board number 09785-1M. The 09785-1M pattern follows Wistron numbering, the ODM that built this board for Sony. Images like this are written to the SPI flash chip with a programmer to repair a corrupted BIOS or a board that will not start. Save the current chip contents first, compare the board markings on the PCB, and confirm the image size matches the chip.
