Step 1
Install the CPU:
1. Locate the CPU ZIF (Zero Insertion Force) socket on the upper-right
sector of your mainboard (between the back-panel connectors and the
DIMMmemoryslots).
2. Pull the CPU ZIF socket lever slightly sideways away from the socket
to unlock the lever, and then bring it to an upwardly vertical position.
3. Place your PPGA/FC-PGA370 processor in the ZIF socket. Note that the
CPU’s edges have been purposely designed non-symmetrically to prevent
from insertingtheprocessorinthewrongdirection. Thefollowing diagram
demonstrates the correct placement of the CPU in the ZIF socket. You can
seethat the two blunt-edged corners should face towards thesocket-lever.
4. Slightlypush the PPGA/FC-PGA370 processor intothe socket without
applying excessive force while making sure there is no gap between CPU
and socket. Then lower the socket-lever all the way down to its horizontal
position and lock it to secure the CPU in place.
5. The PPGA/FC-PGA370 processor requires a set of heatsink/fan to ensure
proper cooling of the processor. If heatsink/fan having not been already
mounted on your CPU, you must purchase the heatsink/fan separately
and have it installed. Plug the cable throught the heatsink/fan in the CPU
fan power connector located nearby. Note that there are several types of
CPU fan connectors. Normally, if your mainboard supports the hardware
monitoringfunction,a3-pinfanpower connector should allowyoursystem
to detect the CPU fan’s speed . The CPU fan can also run with a 2-pin fan
power connector, however, detection of CPU fan’s speed is not supported.
Another type of CPU fan may feature a large 4-pin fan power connector,
which does not support CPU fan's speed detection and must be directly
connectedto the system’s power supply unit. Please referto the following
diagram.

Step 2.
Set Jumpers
This mainboard is jumperless! The default jumper settings have been set for
the common usage standard of this mainboard. Therefore, you do not need
to reset the jumpers unless you require special adjustments as in any of the
followingcases:
1. Over-clock your CPU
2. Clear CMOS
3.SettingDDRVoltage
Forfirst-time DIY system builders, we recommend thatyou do not change the
defaultjumpersettingsifyouarenottotallyfamiliarwithmainboardconfigu-
rationprocedures. Thefactory-setdefaultsettingsaretunedforoptimum
system performance. For the advanced users who wish to customize their
system,section 3.2 Jumper Settingswillprovidedetailedinformationonhow
to configure your mainboard manually.
Step 3.
Install DDR SDRAM System Memory
Toinstallmemory,insertDDRSDRAMmemory module(s) in DIMMslot(s).
Note that DDR SDRAM modules are directional and will not go in the DIMM
slotsunlessproperlyoriented. Afterthemoduleisfullyinsertedintothe
DIMMslots,lifttheclipsofbothsidesoftheDIMMslottolockthemodulein

Step 4
Install Internal Peripherals in System Case
Before you install and connect the mainboard into your system case, we
recommendthatyoufirstassemblealltheinternal peripheral devices into the
computerhousing, including but not limited to thehard disk drive (IDE
/HDD),floppydiskdrive(FDD),CD-ROMdrive,andATXpowersupplyunit.
Thiswill greatly facilitate in making the connections tothe mainboard de-
scribedbelow.
ToinstallIDE&FDDdrives,followthisprocedure:
1. Set the required jumpers on board each device according to the
instructionsprovidedbythemanufacturer.(IDEdevices,HDD,and
CD-ROM have to set jumpers on Master or Slave mode depending
on your willing to install more than one device for each kind.)
2. Connect IDE cable and FDD cable on the back-panel of the internal
peripheral devices to the corresponding headers on board. Note that the
cable should be oriented with its colored stripe (usually in red or magenta)
connected to pin#1 both on the mainboard IDE or FDD connector and on
thedeviceaswell.
3. Connect an available power cable through your system power supply unit
to the back-panel of each peripheral device. Note that the power cable
isdirectional and cannot fit in if not properlypositioned.

- 15 -
Step 5
Mount the Mainboard on the Computer Chassis
1. You may find that there are a lot of different mounting hole positions
both on your computer chassis and on the mainboard. To choose a
correct mounting hole, the key point is to keep the back-panel of the
mainboard in a close fit with your system case, as shown below.
2. After deciding on the proper mounting holes, position the studs between
the frame of chassis and the mainboard. The studs are used to fix the
mainboard and to keep a certain distance between the system chassis
and the mainboard, in order to avoid any electrical short between the
board and the metal frame of chassis. (If your computer case is
alreadyequipped with mounting studs, you willneed to tighten screws to
attachthe mainboard.)
Note: In most computer housings, you will be able to find 4 or more
attachmentpointsto install mounting studs and fix the mainboard.
If there aren’t enough matching holes, then make sure to install at
least 4 mounting studs to ensure proper attachment of the
mainboard.

- 16 -
Step 6
Connect Front-Panel Switches/LEDs/Speaker/USB connectors
You can find there are several different cables already existing in the system
caseandoriginatingfromthecomputer’sfront-paneldevices(HDDLED,
Power LED, Reset Switch, PC Speaker, or USB devices etc.) These cables
serve to connect the front-panel switches, LEDs, and USB connectors to the
mainboard’s front-panel connectors group (JP10, JP7, and JP8), as shown
below.
