BIOS firmware for the Lenovo ThinkPad Edge E40 on the Quanta motherboard DAGC5AMB8F0, revision F, supplied as a 3.04 MB RAR archive. Use it to reprogram the SPI flash on a board that will not boot after a corrupted update, writing it with an external programmer. DA-prefixed numbers are Quanta board codes, so match both the code and the revision letter on the PCB. Back up the existing chip first to keep serial and system data, and check that the image size equals the chip capacity.
