Working BIOS dump for Quanta mainboard DA0HKDMB6D0, revision D, supplied as a 13.6 MB RAR. The same board appears in the Sony Vaio VJF152C11N, but the file name itself names no laptop model. The DA0 code is Quanta's board numbering, so match it and the revision on the PCB. Before programming the SPI chip with a programmer, back up the original contents, which hold serials and system data, and check that the extracted image size equals the flash capacity, since an image of the wrong size will not fit.
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.
