BIOS firmware archive for a Sony VAIO laptop built on the MBX-224 motherboard, with the name also listing the M960 and M970 model references, which appear to be Sony internal codes tied to that platform. The RAR file is 948 KB and needs extracting before use. Technicians typically write such a dump to the SPI flash chip with a hardware programmer when a unit is bricked or will not post. Confirm that MBX-224 is printed on the PCB, read and save the original chip contents first, and check that the image size matches the flash capacity.

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 →
