ZIP archive of BIOS firmware for the HP CQ57 notebook, 1.85 MB compressed. The name gives no board number, revision or BIOS version, so open the archive and inspect the image before relying on it. CQ57 machines were produced on more than one motherboard, so checking the board number printed on the PCB is worthwhile. Back up the existing SPI chip with a programmer, then confirm that the extracted image size equals the chip capacity before writing.
