BIOS archive for the Sony VAIO SVE111B, version V181, on the MBX-272 motherboard. MBX is Sony's internal board numbering, found on a label or silkscreen on the PCB. Technicians use such an image to reprogram the SPI flash directly when the laptop is stuck without POST or a BIOS update went wrong. Confirm the MBX-272 marking matches, ensure the image size equals the chip capacity, and keep a full read of the original chip in case its settings or serial data are needed.
