BIOS image for the Lenovo ThinkPad L14 Gen 2, labelled as fully working, in a 16.8 MB RAR archive. The board is linked to LCFC number NM-D391, which follows the numbering used by Lenovo's own ODM. The archive size suggests one or more images for larger flash chips. Use it to reflash the SPI chip with a programmer when the laptop is bricked. Verify the NM number on the PCB, save the original chip contents first since they may hold serial and other unique data, and match image size to chip.
