The Pentium™ II Processor
Figure 2-1
Figure 2-2 Figure 2-3
The Pentium™ II and Celeron™ processor is the next member of the P6 processor family.
It combines the architectural advances in the Pentium Pro processor with the instruction set
extensions of MMX technology. It is fully compatible with the huge base of Intel architec-
ture-based PC software. Additional, the Pentium™ II processor delivers new levels of
performance for advance media and communications software including powerful, realistic
graphics and imaging capabilities, video conference, and the ability to run full-screen, full-
motion video. The combination of these advanced technologies makes the Pentium™ II
processor the ideal choice foe executing modem 32-bit compute-intensive and multimedia-
enhanced application work loads using advanced 32-bit operating systems.
The Pentium™ II and Celeron processor both have a separate, 32KB, on-chip, non-blocking
L1 cache which run at the processor frequency, Pentium™ II processor also has a 512KB or
256KB on-board L2 non-blocking cache runs at half the processor speed.
The Pentium™ II processor using Single Edge Contact Cartridge (S.E.C.C.) and S.E.C.C.2
packaging technology which enables high volume availability, improved handling protec-
tion.
The Celeron™ processor using Single Edge Processor Package. ( S.E.P.P.)

What does the URM (Universal Retention Mechanism) consist of
Pentium II processor requires the Retention Mechanism (RM) and optional Heat Sink
Support (HSS) to hold the base processor in the S.E.C. cartridge.(or SECC 2)
Following installation procedure will display how to install these mechanism.
Retention Mechanism package consists of 2 separate parts and optional Heat Sink Support
consists of 3 separate parts.
Normally, depend on the type of heat sink, Heat Sink Support is not always available. For
some heat sink attached on pentium II processor might not fit to install the Heat Sink
Support. The introduction of Heat Sink Support installation on this manual only for your
reference.
Universal Retention Mechanism (URM) -
Plastic Guide with captive nuts that hold the
S.E.C. Cartridge in the Slot1 connector.
(Refer to Figure 2-4)
URM Attach Mount (URMAM) -
Bolt/Bridge assemblies inserted up through
the bottom of the mainboard. Then secures the
URM to URMAM (two URMAM required per URM).
(Refer to Figure 2-5)
Figure 2-4
Figure 2-5
Installthe UniversalRetentionMechanism andHeatSink Support
Place the mainboard on a workbench (not in a chassis). Be sure that the mainboard is bare
(that is, no DIMMs, cables, or cards are installed).
Install the Retention Mechanism :
1. Finds out the Universal Retention
Mechanism (URM) Mounting Holes
of Slot1 on HOT-661/P main board.
(Refer to Figure 2-6)
2. Install two Universal Retention
Mechanism Attach Mounts (URMAM)
with Bolt/Bridge assemblies inserted
up through the bottom of the
mainboard. (Notice the URMAM's
bridge orientation as Figure 2-7)

Push the latches on the processor toward the center of the processor until they click into
place.
Hold the processor so that the fan shroud is facing toward the Heat Sink Support Base bar on
the mainboard. Slide the processor into the Universal Retention Mechanism. Ensure that the
alignment notch in the processor fits over the plug in Slot 1. Push the processor down firmly,
with even pressure on both sides of the top, until it is seated.
Push the latches on the processor outward until they click into place in the Universal Reten-
tion Mechanism. The latches must be secured for proper electrical connection of the proces-
sor.
Attach the end of the power cable to the three-pin connector on the mainboard or to the CPU
fan connector on the HOT-661/P.

Celeron™Processor S.E.P.P.OnlyRetention MechanismAssembly
Procedures
These procedures have been included to help assemble the S.E.P.P. (Single
Edge Processor Package) only Retention Mechanism.
Please follow them exactly:

SEPP (Figure 2-12)
Heatsink (Figure 2-13)
Heatsink Retention Clip (Figure 2-14)
Primary Side
Figure 2-13
Figure 2-14
Procedures
Assemble all parts on a static free bench using
proper operator grounding and an ESD mat.
Carefully insert all four heatsink clip legs into
SEPP. (Figure 2-15)
Clip base must be located on thenon-primary
side.(Figure 2-16) FYI - The side of the clip plate
which touches the substrate is covered with a
mylar insulator. This insulator prevents the clip
from shorting lines on the substrate.
Before you fully engage two legs of the clip into
the heatsink (Figure 2-17), make sure you remove
the blue film covering the thermal interface. The
blue film protects the thermal interface from
damage during shipping.
Grasp the heatsink clip assembly between the clip
base and the heatsink. Do not bend or apply
pressure directly to SEPP.
Using a nonmetallic stock or screw driver, push
the remaining two clip legs into the heatsink.
Caution: Take care not to contact passively or
scratch SEPP when using screw driver or bar
stock.
Verify that all the feet on the clip are fully en-
gaged and seated on the heatsink. (Figure 2-18)

HOT-661/P featuring CPU Speed Soft-Configure function. The user can adjust CPU Host
Clock and CPU Clock Ration from BIOS. When the system power-on first time, BIOS will
set CPU clock speed to233 MHz or 350 MHz automatically depend onthe CPU type. If
your CPU speed higher than 233 MHz or 350 MHz., you only have to entry BIOS to set CPU
speed to the higher one.
For the practiced user, HOT-661/P also provides Hard-Configure function to adjust your CPU
Speed. You can adjust your CPU Host Clock on JP39 and adjust your CPU Clock Ratio on
JP37 manually. Please refer to next section on next two pages.
Soft-Configure CPU Clock from BIOS
1) Inserting jumper pack on AUTO group of JP37.
2) Leave jumper JP39 open.
Hard-Configure CPU Host Clock and CPU Clock Ratio.
1) Removing jumper pack from JP37.
2) Inserting mini jumpers properly on JP37 for desired CPU Clock Ratio.
3) Inserting mini jumper/s properly on JP39 for desired CPU Host Clock.
(Above graphics show to configure
CPU Speed to 300 MHz - 66 MHz x 4.5)
Jumpers
CPU Clock Speed Selection - JP39 and JP37
Several hardware settings are made through the use of jumper caps to connect jumper pins on
the main board. The jumper's pin 1 on main board will be on the top or on the left when hold-
ing the main board with the keyboard connector away from yourself.
Jumpers with two pins will be shown as for Close (On) and for Open (Off).
To connect the pins, simply place a plastic jumper cap over the two pins.

Special Tip for User's Reference Only
HOT-661/P mainboard provides a specialJumper
JP45 to overspeed your 66 MHz based Pentium II and
Celeron processor to 100 MHz when jumper group
JP37 set to MANUAL.
Normally, CPU Host Clock 100 ~ 112 MHz are not
available for 66 MHz based processor no matter Soft-
Configure or Hard-Configure.
But, when pull out mini jumper from JP45 (let it open),
the user can Hard-Configure your 66 MHz based
processor to 100 MHz.based. For example, overspeed
your 266 MHz (66 MHz x 4) Celeron to 300 MHz
(100 x 3) or more.
