BIOS dump for the Lenovo IdeaPad Z580 on Quanta board DALZ3AMB8E0, revision E, in a 1.35 MB RAR. Quanta numbers its boards with a DA prefix, a project code, here LZ3A, and a revision letter. The image is used to reflash the SPI chip when the laptop shows no display, fails to post or is stuck after a failed update. Read and back up the original chip with a programmer first, confirm revision E on the PCB and verify the image size matches the flash capacity before writing.
