BIOS backup read from a Quanta DA0HK9MB6D0 motherboard, revision D, stored in a 6.39 MB RAR archive. No laptop brand or model is given, so identify the board by its Quanta code and revision silkscreen. Quanta's DA0 prefix covers boards for HP, Acer, Dell, Lenovo and others. A backup like this can restore a board with a corrupted flash when programmed onto the SPI chip with a hardware programmer. Since it comes from another unit, dump your own chip first and confirm the image size matches.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
