BIOS dump for the ThinkPad T410i on board 09A21-3, a board built around the Intel QM57 chipset, packaged as a 3.84 MB RAR archive. The 09A21 number follows the Wistron scheme used for this ThinkPad generation. Technicians flash an image like this to the SPI chip with a programmer when a board will not post or has a corrupted firmware region. Verify that the board number and revision on the PCB match, back up the current chip contents first, and check that the image size suits the chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
