BIOS and EC firmware set for an HP laptop using Quanta board DAG7BMB48C0, revision C, also labelled G7BM-C. The 7.69 MB ZIP should contain both the system BIOS and embedded controller images, useful when a board is dead, will not charge or shows a blank screen after a failed update. The DA prefix with a project code is Quanta numbering. Write the images with an SPI programmer only after saving the original chip contents, and check that each file size matches its flash chip.
