Firmware archive for a Sony VAIO SVS13 series notebook, labelled 140 and built on the Sony MBX-161 motherboard. Sony identifies its VAIO boards with the MBX-xxx scheme, which is printed on the PCB and must match before flashing. The 1.45 MB RAR likely holds a BIOS dump for restoring a laptop that will not post after a failed update or chip corruption. Use an SPI programmer, save the original chip contents first, and confirm the flash capacity before writing.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
