Firmware archive for the HP Compaq 420 notebook, a 2.33 MB ZIP. The name gives only the model, without a board number, revision or chip type, so confirm the contents after unpacking. A BIOS dump of this kind is commonly written to the SPI flash chip with an external programmer to revive a board that stays dark or fails to boot. Compare the motherboard markings with the intended model, check that the image size matches the chip capacity, and keep a copy of the original read before programming.
