The Mark VI BIOS[1] was a built-in electronic magnification system of the Mark VI MJOLNIR Powered Assault Armor.

It allowed for a 2x magnification without the use of firearm optics, such as the BR55HB SR Battle Rifle's 2x crosshairs. When the Mark VI wearer used an optic-equipped firearm, the Mark VI BIOS was automatically substituted for the firearm's specialized optics.

The Mark VI BIOS was not restricted to the MJOLNIR lineage of helmets: it was equipped in the self-contained powered Hayabusa Armor's helmet and the Orbital Drop Shock Trooper helmet.
