Sony VAIO SVT1312V1ES BIOS dump packed in a RAR archive, tied to Sony board number MBX-265 and carrying the version token R0150D4 in its name. Technicians use an image like this to recover a laptop that no longer posts after a failed update or corrupted SPI flash, writing it with a CH341A or similar programmer. Sony uses the MBX-xxx code on its own mainboards, so confirm the label on the PCB matches before flashing. Always read and save the original chip contents first, and check that the image size equals the capacity of the flash chip.
