Patched BIOS image for the Lenovo ThinkPad T450, described in the name as unlocked, which usually means supervisor password or other security locks have been bypassed in the dump. The 5.93 MB RAR contains firmware for writing to the SPI flash chip with an external programmer and clip. Always read and keep the original chip contents first because they include machine-specific data such as serial numbers. The board number is not stated, so check the PCB markings and chip capacity before writing to the flash.
