Working BIOS with matching EC firmware for an HP 15 laptop on Quanta board DA0U8CMB6B0, revision B. Quanta uses this DA0...MB...0 numbering for boards it builds for brands such as HP. Program the files with a SPI programmer to recover a board with a corrupted BIOS or an EC that is not responding. Check that the board revision matches, read and keep the original chip contents first, and confirm that each image size fits its target flash chip 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.
