Archive for the Lenovo ThinkBook 14 G2 ITL, machine type 20VD, associated with the mainboard LA-K051P. The LA-xxxxP format follows the Compal numbering scheme, so Compal is the ODM behind this board. The 6.67 MB size suggests BIOS or EC firmware, possibly with notes, though the name does not say. Extract it to check the contents, verify the LA-K051P number on your PCB, and before programming any SPI image, save the original chip and confirm the image size matches the flash capacity.
