The MJOLNIR Mark VI BIOS is the basic input/output system, standard firmware interface for the MJOLNIR Mark VI armor.[1]


The Mark VI BIOS is firmware, designed to be the first code run by the Mjolnir Armor when activated. The initial function of the BIOS is to identify, test, and initialize system devices such as the heads-up display, energy shield systems and other hardware.

The BIOS handles most of the MJOLNIR's software functions when initiated. Updates to the BIOS allow newer hardware to be supported and function. BIOS versions can be viewed though the Mark VI's magnification system when no weapon is being held or no zoom-supported weapon is being held. The Mark VI's current BIOS version is S43.3945782.01.[2]


  • In the Halo 3 Beta, the binary code to the right of the Mark VI BIOS translates to "Dave," a reference to David Candland, Bungie's interface designer.
  • In the Halo: Reach Multiplayer Beta, when the player zooms in using the MJOLNIR's zoom function, it reveals the same BIOS for the Mark VI. However, this is merely a placeholder as the Mjolnir Armor worn in the game is the Mark V.
