2-3 INSTALLATION GUIDE
We will now begin the installation of the motherboard. Please follow
the step-by-step procedure designed to lead you to a complete and
correct installation.
Warning: Turn off the power to the motherboard, system
chassis, and peripheral devices before performing any
work on the motherboard or system.
Step 1. Single or Dual CPU Installation
Notice 1 (Dual processor): When installing two processors
(Dual CPU), please make sure the front side bus, working
frequency, and the specification number are identical for both
processors.
Notice 2 (Single processor): If you are using a single
processor, preferably install the processor in Slot2 #1, then
insert the FSB Termination Card in the available Slot2 #2.
Your SY-D6IGA motherboard comes with a DRM (Dual Retention
Mechanism) Assembly. The DRM Assembly is used to hold both
Single or Dual Pentium® II Xeon™& Pentium® III Xeon™
processors attached to the Slot2 #1 or Slot2 #2 slot connectors on
the motherboard.
Follow these instructions to install your Xeon™processor correctly.

Hardware Setup SY-D6IGA
10
1. Mount the Motherboard on the Computer Chassis
You must first install the SY-D6IGA motherboard on the computer
chassis. The motherboard should be bare (without DRM and CPU)
and disconnected from any power source.
Position the motherboard with its mounting holes facing the
corresponding attachment holes on the chassis and tighten the
motherboard mounting screws.
2. Check the Parts Required for CPU Installation
qPart 1: DRM (Dual Retention Mechanism)
This motherboard is shipped with a DRM (Dual Retention
Mechanism) assembly to hold the single or dual Xeon™
processor in Slot2 #1 and Slot2 #2.
DRM Mounting Holes
Chassis Mounting Holes

Hardware Setup SY-D6IGA
11
FSB Termination Card
(To be inserted in Slot2 #2)
qPart 2: CPU Heat Sink & Fan
SOYO has also included a heavy-
duty Heat Sink & Fan assembly for
better heat dissipation of the CPU.
We recommend that you use this
instead of the heat sink that comes
with your CPU.
qPart 3: FSB Termination Card
The FSB (Front Side Bus)
Termination Card must be
inserted in the unoccupied Slot2
connector #2 in a Single processor
configuration. If you install only one
processor, fit it in Slot2 #1, and
insert the FSB Termination Card in
the available Slot2 #2.
3. Mount the CPU Heat Sink & Fan Assembly
The CPU Heat Sink & Fan assembly provided by SOYO provides
better heat dissipation capability. Remove the original heat sink at
the back of the CPU SEC cartridge and affix SOYO’s Heat Sink &
Fan assembly by securing the four mounting screws to the CPU’s
thermal plate.

Hardware Setup SY-D6IGA
12
4. Install the DRM Assembly
4(a) Locate Slot2 #1 & Slot2 #2 connectors and the DRM
mounting holes on the motherboard. Note that Slot2 #1 is
located closer to the middle of the motherboard while Slot2
#2 is situated near the edge of the board.
4(b) Attach the two fan cables of the DRM Stand (the one
equipped with 2 fans) to the fan power connectors labeled
DRMFAN 1 & 2 on the motherboard.
4(c) Affix this DRM Stand (the one equipped with 2 fans) to the
motherboard and then fix the DRM Stand by securing two
DRM mounting screws at the base of the DRM Stand to
the chassis.

Hardware Setup SY-D6IGA
13
4(d) Mount the second DRM Stand (the one without fans)
opposite from the DRM fans (between the back panel
connectors and Slot2 sockets) and use two DRM mounting
screws to secure its base to the motherboard.
Note:If your system is using two chassis cooling fans, plug
the second fan cable to the chassis fan power connector
labeled CHAFAN 2, now. Once the second DRM Stand is
mounted, it will block the CHAFAN 2 connector, providing
insufficient clearance to either attach or remove the fan
power connector cable.
5. Install the First Processor in Slot2 #1
Record the working frequency and specification number of your
CPU that should be clearly marked on the CPU cover.
Pentium® II Xeon™Processor Pentium® III Xeon™Processor
400 MHz (100 x 4.0) 500 MHz (100 x 5.0)
450 MHz (100 x 4.5) 550 MHz (100 x 5.5)
S/N: S/N:

Hardware Setup SY-D6IGA

5(a) Clip the DRM Top onto the processor with the DRM Top
mounting holes facing away from the processor’s heat sink
assembly.
5(b) Slide-in the processor into the DRM Assembly and insert it
in Slot2 #1, while making sure that the heat sink assembly
is facing towards the center of the motherboard.
Important: The Slot2 connector is directionally keyed, and
the processor will not go in unless it is properly oriented,
as shown in the figure.
5(c) Secure the DRM Top bar to both DRM stands by using two
mounting screws.
5(d) Connect the processor cooling fan cable to the CPU fan
power connector labeled CPUFAN on the motherboard.

Hardware Setup SY-D6IGA
15
6. (Dual Processor Configuration)
Install the Second Processor in Slot2 #2
If you are installing a second processor in Slot2 #2, apply the same
procedure as in step 5. However, in step 5(a), clip the DRM Top onto
the processor with the mounting holes facing towards the heat sink.
Notice 1: When installing two processors, make sure the front side
bus and working frequency are identical for both processors. Do
NOT install different types of CPU at the same time, for example,
Pentium® II Xeon™(400/450 MHz) and Pentium® III Xeon™
(500/550 MHz) processors may not work properly when installed
together in a dual configuration. We strongly recommend using two
processors with the same specification number in dual processor
configuration.
Notice 2: If two processors are installed in the DRM assembly, then
the clearance between processors will be insufficient and not allow
the use of a heat sink & fan assembly on the second processor (the
one installed in Slot2 #2). Cooling of the second processors will be
provided by the two DRM fans. If you install a heat sink on the
second processor, only use a narrow gage heat sink so as not to
obstruct the flow of air between the two processors.
7. (Single Processor Configuration)
Install the Termination Card in Slot2 #2
If only one processor is installed in your system, you are required to
insert the FSB Termination Card in the available Slot2 #2.
Note: If you are using a single processor, you must install the
processor in Slot 2 #1, then insert the Termination Card in Slot 2
#2, in this order.

Hardware Setup SY-D6IGA
16
7(a) Insert the termination card in Slot2 #2, while making sure
that the two notches at the base of the card align perfectly
with the keys in Slot2 #2 connector.
Important: The Slot2 connector is directionally keyed, and
the termination card will not go in unless it is properly
oriented, as shown in the figure.
