Firmware for the Lenovo L-IG41M desktop motherboard, version 1.0, contained in a 614 KB RAR archive. The G41 in the board name points to an Intel G41 chipset platform, common in older Lenovo desktops. This dump serves to reprogram the SPI BIOS chip when the board stays dark or fails after an interrupted update. Note that the similarly named L-IG41M3 is a different board. Confirm the label and version on the PCB, back up the original chip, and confirm the image size fits.
