Overview
Pentium II
The Pentium® II Processor is the 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
built-in direct multiprocessing support. In order to achieve multiprocessing, and
maintain the memory and I/O bandwidth to support it, 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) 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 components 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 reusable
heatsink to minimize fit issues for serviceability, upgradeability 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
denoted as ‘Slot 1 connector’ in this and other documentation.
The entire enclosed product is called the Pentium
®
II Processor. The packaging
technology and each of the physical elements of the product are referred to using
accurate technical descriptions. This allows clear reference to the products as just a
IntroductionP2-100B
Page 1-3
processor. This is the model used in past packaging technologies like PGA, TCP,
PQFP, DIP, etc.
S.E.C. Cartridge Terminology
• Pentium® II Processor
The new enclosed card packaging technology is called a “Single
Edge Contact cartridge.” This is similar to previous names for
packaging technology such as PGA or TCP.
• Processor card
The green PCB (with or without components on it)
• Processor core
The silicon on the PLGA package on the PCB
• Cover
The plastic cover on the opposite side from the thermal plate.
• Slot 1
The slot that the S.E.C. cartridge plugs into, just as the Pentium
®
Pro processor uses Socket 8.
• Retention mechanism
Formerly ‘retention module’ the dual posts, etc. that holds the
cartridge in place.
• Thermal plate
The heatsink attachment plate.
• Heat sink supports
The support pieces that are mounted on the mainboard to provide
added support for heatsinks.

The Pentium

II Processor is the first
product to utilize the S.E.C. cartridge
technology and Slot 1 connector. Unless
otherwise noted, any references to
“Pentium® II Processor,” “Pentium® II
Processor/Slot 1 processor” or Processor” will apply to both the Pentium® II
Processor desktop processors.

Accelerated Graphics Port
(AGP or A.G.P.)
Typically, 3D graphics rendering requires a tremendous amount of memory, and
demands ever increasing throughput speed as well. As 3D products for the personal
computer become more and more popular, these demands will only increase. This
will cause a rise in costs for both end users and manufacturers. Lowering these
costs as well as improving performance is the primary motivation behind AGP. By
providing a massive increase in the bandwidth available between the video card and
the processor, it will assist in relieving some of these pressures for quite sometime.
Hardware Monitoring
Hardware monitoring allows you to monitor various aspects of your systems operations and status. The features include CPU temperature, voltage and RPM of fan.
Desktop Management Interface
(DMI)
DMI, or Desktop Management Interface, is a BIOS level method for monitoring
specific BIOS related hardware features. It allows the BIOS to collect and store
information specific to the system, so that vendors and system integrators will have
greater access to information regarding system configuration and design. This allows
for better troubleshooting, migration planning, and upgradeability decision making.

ATX
POWER SUPPLY
P2-100B Board
Power-On/Off (Remote)
The P2-100B has a single 20-pin connector for ATX power supplies. For ATX
power supplies that support the Remote On/Off feature, this should be connected to
the systems front panel for system Power On/Off button. The systems power On/
Off button should be a momentary button that is normally open.
The P2-100B has been designed with “Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off button,
and the other is the "Soft Off" function (coming from the P2-100B’s onboard circuit
controller) that can be controlled by the operating system. Windows 95 will control
this when the user clicks that they are ready to Shutdown the system.
