Chapter 1 System Overview The Dell® OptiPlex® N computers are high-speed, upgradable computers designed for centrally managed network operation. These computers have a small-footprint, locked chassis with no externally accessible drives. The OptiPlex N computers use the Intel® Pentium® microprocessor with MMX™ technology. The microprocessor is installed in a type 7 ZIF socket, allowing the computer to be upgraded when faster microprocessors become available. The Pentium microprocessor contains a built-in clock multiplier circuit, which increases the internal operating frequency to a multiple of the system clock frequency. The microprocessors for Dell OptiPlex N computers operate at a frequency of 166 MHz, 200 MHz, or 233 MHz, derived from a system clock frequency of 66 MHz. These Dell computers incorporate the high-performance PCI expansion bus. This bus is built into the system board, which also integrates the microprocessor, memory controller, hard-disk drive controller, video controller, and other elements of the basic computer.

T

OptiPlex
®
N computers are high-speed, upgradable computers
designed for centrally managed network operation. These computers have a
small-footprint, locked chassis with no externally accessible drives.
The OptiPlex N computers use the Intel

Pentium
®
microprocessor with
MMX
™
technology. The microprocessor is installed in a type 7 ZIF socket,
allowing the computer to be upgraded when faster microprocessors become
available.
The Pentium microprocessor contains a built-in clock multiplier circuit, which
increases the internal operating frequency to a multiple of the system clock fre-
quency. The microprocessors for Dell OptiPlex N computers operate at a
frequency of 166 MHz, 200 MHz, or 233 MHz, derived from a system clock
frequency of 66 MHz.
These Dell computers incorporate the high-performance PCI expansion bus.
This bus is built into the system board, which also integrates the micro-
processor, memory controller, hard-disk drive controller, video controller, and
other elements of the basic computer.
