BIOS firmware archive for the Lenovo ThinkPad X220i, with H0225-3 in the name, most likely a board or unit reference rather than a confirmed revision. The ZIP holds about 5.21 MB, so it may contain more than one image, for example a main BIOS dump plus a second chip or notes. Technicians use such dumps to recover a laptop that will not power on or post after a corrupted flash. Before writing anything, read and save the original SPI contents with a programmer, and confirm the image size matches the chip capacity.
