BIOS image pack for the Sony VAIO VPCEB15 on board MBX-223, marked as unlocked, which usually means the BIOS password or lock has been removed in this dump. The archive should be written to the SPI flash with an external programmer such as a CH341A. Always read and save the original chip contents first, since serial and configuration data live there. Check that the dump size equals the chip capacity, and that the MBX-223 number on the PCB matches, or the laptop may not start after flashing.
