Patched BIOS for the Lenovo ThinkPad T440p, described as an unlock image, which typically refers to removing restrictions such as a supervisor password or whitelist. The name gives no version or board number, so check what the archive contains. Patched images are written with an SPI programmer directly to the chip. Always read the original contents twice and compare before writing, keep that backup, and verify the image size matches the flash chip, since mismatched images will not fit.
