BIOS firmware for a Sony VAIO VPC-EA series laptop on Sony board MBX-224, with the name also carrying an M960 MP MB code identifying the mainboard. Sony uses MBX numbers for its VAIO board families, so the MBX code on the PCB label must match. The 3.17 MB RAR holds an image for reflashing the SPI chip on units with no boot or corrupted firmware. Read the original chip with a programmer and save it before writing, and check the dump size against 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 →
