BIOS dump for the Lenovo G770 laptop on Quanta board DANLAGMBAB0, supplied in a 1.60 MB RAR. Quanta uses the DA...MB numbering on boards it makes for Lenovo and other brands, and the trailing characters reflect the revision. Use the file to reflash a corrupted SPI chip with a programmer when the machine fails to POST. Save the original contents first, match the board code exactly, and confirm that the image size suits the chip.
