HOT-675 is a highly integrated IBM PC/ATX compatible system board designed to
meet the industry's most demanding desktop applications.
Based on the Intel 82440BX AGPset chipset which support up to 500MHz PentiumTM II
processor with MMX technology.
HOT-675 is equipped with an Accelerated Graphics Port (A.G.P.), a high-performance
interconnect for graphic-intensive application, such as 3D applications. The A.G.P. is
independent of the PCI bus and is designed to exclusively use with graphical-display
devices. The HOT-675 supports 3.3 V A.G.P. devices with data transfer rates up to 133
MHz, allowing data throughput of 500 MB/sec.
The Intel's 82440BX AGPset chipset provides an integrated Bus Mastering IDE control-
ler with two high performance IDE interfaces which allows up to four IDE devices
connection and up to 33 MB/sec of data transfer rates.
The on-board I/O controller provides standard PC I/O functions:
floppy drive interface, two FIFO serial ports, an IrDA device port and a SPP/EPP/ECP
capable parallel port.
HOT-675 is built with two PCI local bus slots providing a high bandwidth data path for
data-movement intensive functions such as graphics, and with two ISA slots.
HOT-675 provides the foundation for cost effective, high performance and highly
expandable platforms, which delivers the latest in the Intel PentiumTM II processor and
new advanced chipset technology.

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.

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
Install the Universal Retention Mechanism
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-675 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 Retention
Mechanism. The latches must be secured for proper electrical connection of the processor.
Attach the end of the power cable to the three-pin connector on the mainboard or to the CPU
fan connector on the HOT-675.

Celeron™ Processor S.E.P.P. Only Retention Mechanism Assembly
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:
Required Components
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 the non-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)

Jumpers
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.
HOT-675 featuring CPU Plug & Play function, the user needn't to adjust onboard system clock
and CPU multiplier. When the system power-on first time, BIOS will set CPU clock
speed to 233 MHz or 350 MHz (depend on CPU external frequency) automatically. 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.
HOT-675 mainboard features a clock generator to provide adjustable system clock frequency.
JP1 is a 6-pin jumpers which determine the system clock frequency 66 MHz to 133 MHz.
CPU Plug & Play function is supported by 66MHz / 100MHz.
HOT-675 mainboard provides Jumper group of JP10 to figure the CPU core clock multiplier.
By inserting mini jumpers on MANUAL group, the user can figure the Host Bus Clock/CPU
Core Clock ratio (multiplier) manually.
CPU Plug & Play function is supported when an Jumper Pack inserted on
AUTOgroup.
Listed diagrams on right side show the sample position on jumper group of JP10:
1) Setting CPU Clock from BIOS
- jumper pack on AUTO.
(Factory default)
2) Adjust multiplier manually from hardware
- jumper pack on MANUAL, multiplier set to 5X manually.

By inserting jumper pack on Row B-C group, the user can Soft-Configure the CPU Host Clock and
CPU Clock Ratio from BIOS.
By removeing jumper pack from Row B-C group and inserting mini jumpers on Row A-B group
properly, the user can configure the CPU Clock Ration (multiplier) manually.
Note: 73, 83 MHz are for 66 MHz based and 103 ~ 133 MHz are for 100 MHz based processor over-

Special Tip for User's Reference Only
HOT-675 mainboard provides a special Jumper J19
to overspeed your 66 MHz based Pentium II processor
to 100 MHz.
Normally, CPU Host Clock 100 ~ 133 MHz are not
available for 66 MHz based processor no matter Soft-
Configure or Hard-Configure.
But, when pull out mini jumper from J19 (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.
