Firomactal drive was a gibberish term that Commander William Riker invented to confuse Morta when he was forced to instruct the Ferengi in the operations of the main computer of a Galaxy-class starship in 2369. Commander Riker claimed that this system was controlled by the Isopalavial interface. He also stated that this system controls the ramistat core and keeps the Ontarian manifold at 40,000 KRG's.
