Firmware dump package for an HP 15 notebook on the Quanta U8C platform, board DA0U8CMB6B0, revision B. Quanta's DA0 numbering encodes the project code, here U8C, and the board revision, so check both on the PCB before use. Unpack the RAR and compare the BIOS image size with the flash chip on the board. Back up the original first, since HP dumps can carry serial and product data that a technician may need to rewrite. It is commonly used to restore boards with no display or no boot after a bad update or corrupted SPI contents.
