BIOS dump for the Lenovo E31-80 notebook, made for the Compal LA-D061P board, version 1.0. LA- numbering is Compal's mainboard scheme, which Lenovo used for many ThinkPad and IdeaPad models. The 4.37 MB RAR should contain an image for the board's SPI flash. Typical use is recovering a dead or bricked board by writing the chip with a hardware programmer. Compare the PCB marking and revision with the name, keep a backup of the factory chip contents, and verify that the image size matches the flash capacity.
