Working BIOS for an HP 15 notebook on Quanta board DAY23AMB6C0, revision C, reported as fully tested, in a 3.75 MB RAR archive. The DA...MB6 code is Quanta's mainboard numbering, showing that Quanta designed the board. Technicians flash this image to the SPI chip with a programmer to fix boot failures, black screens or a corrupted update. Save the original dump first, because it contains machine-specific data, and check that the file size matches the flash capacity and the PCB revision.
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.
