BIOS image for the HP ProBook 450 G6 on board DA0X8JM8E0, revision E, marked UNPASS, which usually means the BIOS supervisor password has been removed. The DA0 prefix with the X8J code fits the Quanta ODM pattern. The RAR is meant for flashing the SPI chip directly with a programmer when the setup password locks the machine. Save the original chip contents first so the serial and product data can be restored, and check the PCB revision is E.
