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 disks." This usage is a recent innovation
reflecting the fact that most IBM-PC clones are now delivered with
an operating system pre-installed at the factory. Other kinds of
hardware are still normally delivered without OS, so this term is
particular to PC support groups.
