BIOS archive for the Sony VAIO SVE141B11V laptop built on Sony board MBX-270. The 3.08 MB ZIP should be unpacked to locate the firmware image and check its size against the SPI chip fitted. Sony identifies its VAIO motherboards with MBX numbers, printed on the board along with revision details. Technicians use such a dump to recover a machine with corrupted firmware by writing it with an external programmer. Read and keep the original chip contents first so system data can be restored if needed.
