BIOS dump for the HP EliteBook 840 G2, read from a W25P16 flash. The W25 prefix indicates a Winbond SPI part, and the 16 in the name points to a 16 Mbit (2 MB) chip, which this image should match. The file is used to reprogram that chip with an external programmer to recover from corrupted firmware or boot faults. Business HP boards often use more than one flash chip, so make sure you are writing the correct one, and save the original contents before programming.
