Firmware dump for a Lenovo ThinkPad on Wistron board 17870-1, project LPM-1, PCB code 448.0DY04.0011, described as fully working and supplied in a 19.3 MB RAR archive. This board number matches the Wistron pattern used for ThinkPad mainboards. The image restores a board that will not start because of corrupted flash, written directly with an SPI programmer. Make a backup of the existing chip before writing, check the 448 code on the PCB, and confirm the image size matches the flash chip.
