Overview
Pentium II or Deschutes Processor
The Pentium® II or Deschutes Processor (The Deschutes Processor as 300/
100MHz, 350/100MHz, 400/100MHz and 450/100MHz speed with 512K-L2 cache
Versions.) is the follow-on to the Pentium® Processor. The Pentium® II or
Deschutes 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
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 or Deschutes Processor card
supports both uni-processor and dual processor implementations.
®
The Pentium
II or Deschutes 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.
II or Deschutes Processor, from a system
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

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 processor. This is the model used in past packaging technologies like PGA,
TCP, PQFP, DIP, etc.
S.E.C. Cartridge Terminology
• Pentium® II or Deschutes 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 L2 cache (TagRAM, PBSRAM)
components keep standard industry
names.

Introduction EP-BXT
EP-BXT Form-Factor
The EP-BXT is designed with ATX form factor - the new industry standard of
chassis. The ATX form factor is essentially a Baby-AT baseboard rotated 90
degrees within the chassis enclosure and a new mounting configuration for the power
supply. With these changes the processor is relocated away from the expansion slots,
allowing them all to hold full length add-in cards. ATX defines a double height
aperture to the rear of the chassis which can be used to host a wide range of
onboard I/O. Only the size and position of this aperture is defined, allowing PC
manufacturers to add new I/O features (e.g.; TV input, TV output, joystick, modem,
LAN, etc.) to systems. This will help systems integrators differentiate their products
in the marketplace, and better meet your needs.
• Smaller size promotes a smaller system size.
• I/O shield does not need to be retooled in an ATX 2.01 or later. Mainboard could
be used in an ATX 2.01-compliant.
• A smaller power supply cam be used. High integration on mainboard reduces the
system costs.

The EP-BXT 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 EP-BXT 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 the
button, and the other is the "Soft Off" function (coming from the EP-BXT’s onboard
circuit controller) that can be controlled by the operating system. Windows 95/98 will
control this when the user clicks that they are ready to Shutdown the system.

Note: Based on the implementation of Intel 440BX PCIset, EP-BXT is able to
provide two host bus frequencies -- either 66 or 100MHz for Slot1 processor
and memory operating. The default is set at 100MHz once Pentium® II
processor to be mounted onto this mainboard. However, no matter what kind
of Slot1 processor you installed, it should come with right memory modules
for normal and stable operation. For example, if you install a Deschutes
processor, you should use the SDRAM module with 100MHz based(or above)
to match the CPU speed. Furthermore, one thing you may need to bear in
mind, before the CPU installation, it is anyway our advice to use JP3 and set
up right speed of Slot1 processor at any time.

System Memory Configuration
Memory Layout
The EP-BXT supports (3) 168-pin DIMMs (Dual In-line Memory Module). The
DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized
DRAM).
• We recommend using SDRAM DIMM can not mixing
with EDO DIMM modules together at 66MHz.
• The EDO DIMM only support pentium
support Deschutes Processor at 100MHz.
• 256MB only Support Registered synchronous DRAM Memory
Modules. The Registered SDRAM DIMM do not mix with SDRAM
DIMM modules together.
• We recommend when installed the 100MHz Deschutes Processor
using DIMM SDRAM must be 125MHz (-8ns) bus speed. If used
100MHz (-10ns) SDRAM may be critical timing for the
motherboard.
• About the “PC/100 SDRAM spec.” information you may visit Intel’s
home page at:
http//developer.intel.com/design/pcisets/memory/index.htm
• DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or
125MHz (-8ns) bus speed.
