BIOS and EC firmware set for the Sony VAIO SVE14 series on board MBX-270, the i5 variant. Sony labels its VAIO mainboards with MBX numbers, and this archive bundles both the system BIOS and the embedded controller code, which handles power, battery and keyboard functions. The 6.48 MB RAR is used when reflashing chips with an SPI or EC programmer. Confirm MBX-270 on the PCB, back up both original chips before writing, and check each image against its target chip capacity.
