BIOS image for the Lenovo ThinkPad T410i, board 09A21-3, with the Intel QM57 chipset. The 3.84 MB RAR is meant for rewriting the system flash with an external programmer when the notebook will not POST or is stuck after a failed update. ThinkPads store serial numbers and other machine-specific data in the flash, so read and keep the original image before erasing. Check that the board number and chipset match your unit, and that the dump size fits the chip.
