Said of machiNes delivered without aN operatiNg system (compare bare metal). "We ordered 50 systems, but they all arrived Nude, so we had to speNd a aN extra weekeNd with the iNstallatioN tapes." This usage is a receNt iNNovatioN reflectiNg the fact that most PC cloNes are Now delivered with DOS or Microsoft WiNdows pre-iNstalled at the factory. Other kiNds of hardware are still Normally delivered without OS, so this term is particular to PC support groups. [JargoN File] (1994-12-13)
