Firmware archive for the Lenovo ThinkPad T570, Wistron board LTS-1 MB 16820-1, with the identifier 488.0AB07.0011 as given in the name. Wistron numbers its boards with a five-digit code and dash suffix, which is printed on the PCB. Such dumps serve to recover a board with corrupted BIOS by programming the SPI chip directly. Extract the archive, compare the board number with yours, back up the original chip using a programmer, and ensure the image size matches the flash before writing.
