BIOS image for an HP 17 laptop on Quanta board DA0R75MB6C0, revision C, archived as RAR and noted as working. Quanta board numbers start with DA, and the final letter and digit give the PCB revision, which should match the board under repair. Write the dump with an SPI programmer to fix boot failures caused by corrupt firmware. Keep a copy of the original chip contents, as it holds serial and product data that may need restoring.
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.
