BIOS firmware for an HP 15-series main board, number DAY11AMB6E0 version E, packed as a 3.86 MB RAR archive. The DA-prefixed code follows Quanta numbering, and the trailing letter E marks the revision, which should match the silkscreen on your PCB. The dump is meant for reprogramming the SPI flash with an external programmer after a failed update or a no-display fault. Back up the existing chip first, and confirm that the extracted image size equals the capacity of the fitted flash chip.
