BIOS image in a ZIP of about 5.7 MB for a board code-named Cotton, with HP-style spare part number 737184-001 and revision A. The name does not give the laptop model, so match the part number and board label before trusting it. Such dumps are flashed to the SPI chip with an external programmer to recover a board that does not boot or shows a blank screen. Save the original firmware first and check that the image size equals the flash chip capacity.
