BIOS dump for the Sony MBX-223 board with the Intel Management Engine region cleaned, meaning the ME section was reset so it initialises fresh instead of carrying over a corrupted state. MBX numbers are Sony's internal VAIO mainboard codes. Clean-ME images are commonly flashed when a laptop powers on but shuts down or fails to boot. Extract the .rar, dump and save the existing SPI chip contents, then compare sizes before writing; serial and model data may need restoring from your backup.
