Installation Guide

Getting Started
WARNING!
Computer motherboards and expansion cards contain very delicate Integrated
Circuit (IC) chips. To protect them against damage from static electricity, you
should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have one,
touch both of your hands to a safely grounded object or to a metal object, such as the
power supply case.
3. Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.
4. Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or remove the ATX
power connector on the motherboard.
Installing the motherboard to the chassis…
If the motherboard has mounting holes, but they don’t line up with the holes on the base and
there are no slo ts to attach the spacers, do not become alarmed you can still attach the spacers
to the mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard
to cut off, so be careful of your hands). In this way you can still attach the motherboard to the
base without worrying about short circuits. Sometimes you may need to use the plastic springs
to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by
the hole. Be careful, don’t let the screw contact any printed circuit write or parts on the PCB that
are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

You may use the 4 screws which come wi th the mai nboard to reinforc e the s upport bet ween P4
CPU heat-sink on the mainboard and chassis.
Please note! In order to follow the installation steps below; your chassis must be
WILLMETTE/850 board design compatible.
Step1: The 4 new mounting holes on the
chassis are for additional support for P4 CPU
heat-sink on the mainboard.
Step2: Please remove 4 sets of plasti c Push-pins
as indicated on Figure2. Remove the white
pins first, then black pins as indicated on
Figure3.

To set up your computer, you must complete the following steps:
Step 1 - Set system jumpers
Step 2- Install the Central Processing Unit (CPU)
Step 3-Install memory modules
Step 4-Install expansion cards
Step 5-Connect ribbon cables, cabinet wires, and power supply
Step 6-Set up BIOS software

Memory Installation
The motherboard has 4 Rambus In-line Memory Module (RIMM) sockets. The BIOS will
automatically detects memory type and size. To install the memory module, just push it vertically
into the RIMM Slot .The RIMM module can only fit in one direction due to the two notches.
Please note; Both RIMM modules inserted on RIMM1 and RIMM2 slots are recommended to
have the same size, frequency. If not, the larger sized module will l be automatically re-sized by
BIOS to match the smaller sized module. The same rule applies to both RIMM3 and RIMM4
slots.
You can insert two RIMMs or four RIMMs into RIMM slots, but C-RIMM (Continuity RIMM)
modules must be inserted into the empty slots.
RIMM
Check RIMM module if it is supported by the
M/B.
Insert the RIMM module into the slot.

CRIMM
Push the ejector tab towards the RIMM.
