Sony VAIO VGN-CR series BIOS dump for mainboard MBX-177, provided in a 595 KB RAR. The small size reflects the older generation of these machines and their lower-capacity flash chips. MBX is the code Sony uses for its VAIO motherboards, so the number printed on the PCB must match before you write. Technicians program such a file to the BIOS chip with an external programmer to recover a failed flash. Save a read of the original chip first and make sure the image size equals the chip capacity.
