A BIOS image for a 450 G5, likely an HP ProBook 450 G5, with the name stating that the password has been cleared. A dump like this is typically used to remove a forgotten supervisor or power-on password by writing it to the SPI flash. The 16 MB size matches a 128 Mbit chip. Read and keep the original chip before programming it. Serial numbers and other unit-specific data may need restoring afterwards, so check the system information once the board boots again.
