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 Proces-

sor 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 perfor-

mance 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 connec-

tion 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

processor. This is the model used in past packaging technologies like PGA, TCP,

PQFP, DIP, etc.

IntroductionEP-BXBS

Page 1-3

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 L2 cache (TagRAM, PBSRAM) components keep standard industry names.

Enterprise Symmetrical

Multi-Processing (SMP)

At last an Enterprise-Class solution for your Bandwidth Critical applications server at

PC prices. This mainboard features the latest Intel Pentium

®

II Processor horse-

power in a Symmetrical Multi-Processing (SMP) configuration previously only

available on RISC and Mainframe systems.

In SMP Operating Systems such as Unix

®

and Windows

®

NT the two main tasks of

I/O and Application thread can be most efficiently done if split evenly over two

CPU’s. The core benefit to you is not only the reduced outlay in infrastructure, but

also the PC-architecture that you need for security of investment and future

compatibility.

This mainboard is also an excellent single-user Workstation solutions for Mission-

Critical 32-bit applications such as Adobe

®

Photoshop for Windows

®

NT, where

double floating-point power can really smooth out your work-load. Also provided are

the latest PC Workstation technologies including A.G.P., USB, and PC2.1 Expansion

Slots.

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. These include features such as CPU temperature, voltage and fan RPM’s.

Adaptec SCSI (Legacy/SE & Ultra-2 LVD)

The EP-BXBS mainboard features the advanced Adaptec AIC-7890 Ultra-2 Wide SCSI

controller. This controller provides support for Low Voltage Differential (LVD) SCSI devices

as defined under the Ultra-2 section of the SCSI-3 standard. LVD SCSI devices allow for data

transfer rates of up to 80 Mbytes/sec and can use cable lengths of up to 12 meters! Addition-

ally the AIC-3860 Adaptec controller is also provided for backwards compatibility with single-

ended (SE) legacy SCSI devices such as SCSI-1, Fast, Fast Wide, Ultra and Ultra Wide. Below

is a chart summarizing the possible data-transfer rates available with SCSI.

Introduction EP-BXBS

Page 1-6

EP-BXBS Form-Factor

The EPoX EP-BXBS is designed with ATX form factor - the latest 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, audio, etc.) to systems. This will help systems integrators differentiate their

products in the marketplace, and better meet your needs.

• By integrating more I/O down onto the board and better positioning the hard

drive and floppy connectors material cost of cables and add-in cards is reduced.

• By reducing the number of cables and components in the system, manufacturing

time and inventory holding costs are reduced and reliability will increase.

• By using an optimized power supply, it's possible to reduce cooling costs and

lower acoustical noise. An ATX power supply, which has a side-mounted fan,

allows direct cooling of the processor and add-in cards making a secondary fan

or active heatsink unnecessary in most system applications.

The EP-BXBS is equipped with an I/O back panel. Please use the appropriate I/O

POWER SUPPLY

EP-BXBS Board

Power-On/Off (Remote)

The EP-BXBS 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-BXBS 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 EP-BXBS’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.
