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.

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.

System Memory Configuration

Memory Layout

The P2-100B supports (3) 168-pin DIMMs (Dual In-line Memory Module). The
DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized
DRAM). The DIMMs may be installed using just one chip.

• We recommend using SDRAM DIMM can not mixing

with EDO DIMM modules together.

• We recommend when installed the 100MHz 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.

AWARD BIOS SETUP

BIOS Instructions

Award’s ROM BIOS provides a built-in Setup program which allows user to modify
the basic system configuration and hardware parameters. The modified data will be
stored in a battery-backed CMOS, so that data will be retained even when the power
is turned off. In general, the information saved in the CMOS RAM will stay un­changed unless there is a configuration change in the system, such as hard drive
replacement or a device is added.

It is possible for the CMOS battery to fail, this will cause data loss in the CMOS
only. If this does happen you will need to reconfigure your BIOS settings.

To enter the Setup Program :

Power on the computer and press the <Del> key immediately, this will bring you into
the BIOS CMOS SETUP UTILITY.

If user set his HDD to NORMAL mode, the maximum accessible HDD size will be
528 Megabytes even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode: A new HDD accessing method to
overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors
shown in setup may not be the number physically contained in the HDD. During
HDD accessing, the IDE controller will transform the logical address described by
sector, head & cylinder into its own physical address inside the HDD. The maximum
HDD size supported by LBA mode is 8.4 GigaBytes which is obtained by the
following formula:

no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x bytes per sector ( 512)

8.4 GigaBytes

LARGE mode: Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some

cases, user do not want LBA). The Award BIOS provides another alternative to
support these kinds of LARGE mode.

CYLS HEADS SECTOR MODE

1120 16 59 NORMAL
560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse
transformation process will be made inside

BIOS P2-100B

INT 12h in order to access the right HDD address!
Maximum HDD size:

no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)

1 GigaByte

Note: To support LBA or LARGE mode of HDDs, there must be some
software involved. All the software is located in the Award HDD Service
Routine (INT 13h). It may fail to access a HDD with LBA (LARGE) mode
selected if you are running under an Operating System which replaces the
whole INT 13h.

UNIX operating systems do not support either LBA or LARGE and must utilize the
Standard mode. UNIX can support drives larger than 528MB.

4-10 HDD Low Level Format

Interleave: Select the interleave number of the hard disk drive you wish to perform
a low level format on. You may select from 1 to 8. Check the documentation that
came with the drive for the correct interleave number, or select 0 for automatic
detection.

Auto scan bad track: This allows the utility to scan first then format by each track.
Start: Press<Y>to start low level format.

4-11 Save & Exit Setup

The “SAVE & EXIT SETUP” option will bring you back to the boot up procedure
with all the changes you just recorded in the CMOS RAM.

4-12 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up
procedure without saving any data into CMOS RAM.

All old data in the CMOS will not be destroyed.
