Firmware archive for a board numbered DA0LVAMB8F0, revision F, compressed as a 7.12 MB RAR. The DA0xxxMBxx0 pattern is Quanta's, the ODM producing boards for HP, Dell, Acer and others; the name does not say which laptop. Expect a BIOS dump for the SPI flash, reprogrammed with a hardware programmer when the machine fails to post or the firmware is corrupted. Check the board marking and revision, compare dump size to the chip capacity, and save the original contents before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
