BIOS dump for a Lenovo ThinkPad P1, machine type 20MD, on Wistron board 17870-1 with project code LPM-1, PCB part 448.0DY04.0011 and an Intel Core i7 configuration, packed in an 8.30 MB RAR archive. The dash-numbered board and 448 part code follow Wistron conventions. Technicians use it to reprogram a corrupted SPI flash with an external programmer. Read and save the original contents first, verify the board numbers on the PCB, and confirm the image size fits the chip.
