Introduction
EPoX is proud to introduce the KP6-FX 2 mainboard to support Intel Pentium ® II
Processor Intel’s latest technology in CPU’s. The KP6-FX 2 is based on Intel’s 82440FX
chipset, and supports uni-Pentium
® II Processor processor. Full specifications include 4
PCI and 4 ISA slots, USB ready, and a special ring-in feature all built into full ATX
format. KP6-FX 2 also supports a memory capacity upto 1GB to run the most demanding
applications. The KP6-FX 2 also uses Easy-Setting-Single-Jumper (ESSJ) to simplify
your CPU clock setting.
1-1 Pentium ® II Processor Overview
The Pentium ® II Processor processor is follow-on to the Pentium ® Processor. The
Pentium ® II Processor, like the Pentium ® Pro processor implements a Dynamic Execution
micro-architecture -- a unique combination of multiple branch prediction, data flow
analysis, and speculative execution. This enables the Pentium
® II Processor to deliver
higher performance than the Pentium ® processor, while maintaining binary compatibility
with all previous Intel architecture processors.
A significant feature of the Pentium ® II Processor, from a system perspective, is the build-
in direct multiprocessing support. In order to achieve multi-processing, and maintain
memory and I/O bandwidth to support them, new system designs are needed. For systems
with dual processors, it is important to consider the additional power burdens and signal
integrity issues of supporting multiple loads on a high speed bus. The Pentium
® II
Processor card supports both uni-processor and dual processor implementations.
The Pentium ® II Processor utilizes Single Edge Contact (S.E.C.) (Figure 1-1) cartridge
packaging technology. The S.E.C. cartridge allows the L2 cache to remain tightly coupled
to the processor, while maintaining flexibility when implementing high performance
processors into OEM systems. The second level cache is performance optimized and
tested at the cartridge level. The S.E.C. cartridge utilizes surface mounted core compo-
nents and a printed circuit board with an edge finger connection. The S.E.C. cartridge
package introduced on the Pentium
® II Processor will also be used in future Slot 1

processors.
The S.E.C. cartridge has the following features: a
thermal plate, a cover and a PCB with an edge
finger connection. The thermal plate allows
standardized heatsink attachment or customized
thermal solutions. The thermal plate enables a re-
usable heatsink to minimize fit issues for service-
ability, upgradability and replacement. The full
enclosure also protects the surface mount
components. The edge finger connection
maintains socketabilty for system configuration.
The edge finger connector is notated as ‘Slot 1
connector’ in this and other documentation.
