The Dataspine was an archived version of J.A.R.V.I.S.
The Roxxon Energy Corporation attacked Stark Archives in an attempt to steal the Dataspine. Iron Man traveled there and attempted to stop them, but was struck by an EMP bomb, which disabled him. He briefly lost consciousness and upon regaining it, he activated his armor's power reserves.
Stark grimly decided that he should destroy the Dataspine to keep Roxxon from getting the archives. Outside, James Rhodes in his War Machine armor, intercepted some Roxxon Dropships to give Stark enough time to activate the Dataspine's self-destruct sequence. After the explosion, the two left, but Roxxon had already got what they wanted.
