Raw BIOS image for the HP ProBook 6565b, dumped from a Macronix MX25L1605D flash chip; that part is 16 Mbit, consistent with the 2 MB file. No version or tested status is mentioned in the name. Technicians use such a dump to recover boards with a corrupted BIOS by writing it with an SPI programmer, often using a test clip or after desoldering the chip. Always read and keep the existing contents before erasing, and check that the chip fitted to your board has the same capacity as the image.
