BIOS archive for a board marked RAINS DIS HR HPC MV MB version V1, a project code associated with HP DV4 laptops with discrete graphics; the name itself states no brand or model. The 1.90 MB ZIP is meant for chip-level recovery with a SPI programmer. Since a V2 board of the same family exists, confirm that your PCB reads V1 before writing. Read and store the original flash contents, and check that the image matches the chip capacity to avoid a failed write.
