Firmware for the Lenovo ThinkPad T520, labelled with the code H0222-5, which may refer to a board or BIOS identifier though the name does not explain it. The ZIP is 5.29 MB and includes no explicit board number, so verify the machine against the PCB before use. Technicians reflash such images with an external SPI programmer to recover a board that stays black or beeps. Dump the existing chip first, as ThinkPads store serial and system data there, and check the image size fits the flash chip.
