BIOS firmware for the HP 15-b052sr notebook on Quanta board DA0U36MB6D0, revision D. Quanta's DA prefix numbering encodes the project, here U36, and the revision letter matters because firmware and parts can change between revisions. The 3.68 MB RAR is meant for reprogramming the SPI flash with a programmer. Back up the original chip, confirm the image size equals the chip capacity, and match the PCB number and Rev D before writing.
