BIOS image for the Lenovo ThinkBook 16 Gen 6 on board 223147-1, with the PCB part number 448.0TF08.0011 also given in the name. The 223147-1 style of board number follows the Wistron pattern, and the 448 part code commonly accompanies it on the PCB label. The file is an 18.8 MB RAR archive. Repair shops flash such dumps to the SPI chip when a laptop fails to post after a bad update. Confirm that the board code matches, read and save the original chip, and check the image fits the flash capacity.
