(^80) PC Hardware: A Beginner’s Guide
A consortium of computer and component manufacturers developed the NLX speci-
fication. This standard is published for all to use. The hope is that by sharing information,
the problems associated with the LPX form factor can be avoided.
TherewerethreeprimaryfocusesoftheNLXstandard:processorandsystemcooling,
the number of connectors for multimedia hardware, and reducing the clutter of interior
cables. The NLX specification features a redesigned airflow for its slim line case. The size
and high operating temperatures of newer and more powerful microprocessors and
high-performance graphics adapters necessitated a new approach to the cooling system
of the PC case. The NLX also addresses the requirement from multimedia systems for
additional I/O connectors on the motherboard and the need to reduce the cable clutter in
the system case that impedes repairs and upgrades.
The Components of the Motherboard
The motherboard is the foundation on which a PC is built. It provides the interconnecting
circuitry through which the primary components of the motherboard receive their power
and pass control signals, data, addresses, and instructions to each other. In short, with aFigure 4-5. An NLX motherboard and riser board. Photo courtesy of Intel Corporation
