Working BIOS and keyboard EC firmware package for an HP 15 laptop on Quanta board DA0P5EMB6E0 revision E, fitted with an AMD Ryzen 5 3500U. The name reports both images as fully working. The DA...MB...0 pattern is Quanta numbering, and HP uses Quanta for many 15-inch models. Use the files to reprogram the main SPI BIOS chip and the KBC/EC flash when a unit shows no power or no display after corruption. Read out the original chips first and confirm the revision printed on the PCB 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.
