Hardware Setup 2-1
Chapter 2. Hardware Setup
Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or
disconnect the power cord before installing or unplugging any connectors or add-on cards. Failing to do
so may cause the motherboard components or add-on cards to malfunction or damaged.
2-1. Install The Motherboard
Most computer chassis have a base with many mounting holes to allow motherboard to be securely
attached on and at the same time, prevented from short circuits. There are two ways to attach the
motherboard to the chassis base:
1. use with studs
2. or use with spacers
In principle, the best way to attach the board is to
use with studs. Only if you are unable to do this
should you attach the board with spacers. Line up
the holes on the board with the mounting holes on
the chassis. If the holes line up and there are
screw holes, you can attach the board with studs.
If the holes line up and there are only slots, you
can only attach with spacers. Take the tip of the
spacers and insert them into the slots. After doing
this to all the slots, you can slide the board into
position aligned with slots. After the board has been positioned, check to make sure everything is OK
before putting the chassis back on.
ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they
are already fastened on the chassis base and are without mounting-holes on the motherboard to align with.

2-2. Install CPU, Heatsink and Fan Assembly
In order to protect the contact pins, please pay
attention to these notices:
1. A maximum 20 cycles of CPU installation
is recommended.
2. Never touch the contact pins with fingers
or any object.
3. Always put on the cap when the CPU is
not in use.
4. Use your right thumb and forefinger to
grasp the CPU package. Be sure to grasp on the
edge of the substrate, and face the Pin-1
indicator toward the bottom-left side. Aim at the
socket and place the CPU package vertical
down into the socket.
1. Place the board so as to let the lever hook
of the socket is on your left side. Use your left
thumb and forefinger to hold the lever hook,
pull it away from the retention tab.
2. Rotate the lever to fully open position.
3. Use your right thumb on the bottom-right
side of the load plate and lift it up to fully open
position.
5. Visually inspect if the CPU is seated well
into the socket. The alignment key must be
located in the notch of package.
6. Use your left hand to hold the load plate,
and use your right thumb to peel the cap off.
AG8 Series
Hardware Setup 2-3
The cap plays an important role in protecting
contact pins. In order to prevent bent pin, PUT
ON the cap after operation or testing.
7. Lower the plate onto the CPU package.
Engage the load lever while gently pressing
down the load plate.
8. Secure the lever with the hook under
retention tab.
For detailed information on how to install your
heatsink and fan assembly, please refer to the
instruction manual came packed with the
heatsink and fan assembly you bought.
10. Press each of the four fasteners down into
the mounting holes.
11. Rotate the fastener clock-wise to lock the
heatsink and fan assembly into position.
9. Place the heatsink and fan assembly onto
the socket. Align the four fasteners toward the
four mounting holes on the motherboard.
12. Attach the four-pin power plug from the
heatsink and fan assembly to the CPU FAN
connector.

2-3. Install System Memory
The Intel 915P Express Chipset MCH memory interface is designed with Flex Memory Technology
supporting single-channel or dual-channel DDR memory configurations.
• To reach the optimum performance in dual-channel configurations, install identical DDR DIMM
pairs for each channel.
• Install DIMMs with the same CAS latency. To reach the optimum compatibility, obtain memory
modules from the same vendor.
• Due to chipset resource allocation, the system may detect less than 4GB of system memory in the
installation of four 1GB DDR memory modules.
• Due to chipset limitation, 128MB DIMM modules or double-sided x16 memory chips are not
supported.
There are several methods of different DDR configurations depending on how the DIMMs are populated
on each system memory channel:
• [Single Channel]: only one channel is populated.
Method
1 512MB - - 2 - 512MB - 3 - - 512MB 4 - - - 512MB
5 512MB 512MB - 6 - - 512MB 512MB
DIMM1 DIMM2 DIMM3 DIMM4
Channel A Channel B
AG8 Series

• [Dual Channel Asymmetric]: both channels are populated, but each channel has a different
amount of total memory. (Channel A≠Channel B)

of total memory. (Channel A＝Channel B)
Method

Power off the computer and unplug the AC power cord before installing or removing memory modules.
1. Locate the DIMM slot on the board.
2. Hold two edges of the DIMM module
carefully, keep away of touching its
connectors.
3. Align the notch key on the module with the
rib on the slot.
4. Firmly press the module into the slots until
the ejector tabs at both sides of the slot
automatically snaps into the mounting notch. Do not force the DIMM module in with extra force as
the DIMM module only fit in one direction.
5. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and
then pull out the DIMM module.
ATTENTION: Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a
grounded metal object briefly.

(11). Floppy and IDE Disk Drive Connectors
The FDC1 connector connects up to two floppy drives with a 34-wire, 2-connector floppy cable. Connect
the single end at the longer length of ribbon cable to the FDC1 on the board, the two connectors on the
other end to the floppy disk drives connector. Generally you need only one floppy disk drive in your
system.
NOTE: The red line on the ribbon cable must be aligned with pin-1 on both the FDC1 port and the floppy
connector.
Each of the IDE port connects up to two IDE drives at
Ultra ATA/100 mode by one 40-pin, 80-conductor, and
3-connector Ultra ATA/66 ribbon cables.
Connect the single end (blue connector) at the longer
length of ribbon cable to the IDE port of this board, the
other two ends (gray and black connector) at the shorter
length of the ribbon cable to the connectors of your hard
drives.
NOTE: Make sure to configure the “Master” and “Slave” relation before connecting two drives by one
single ribbon cable. The red line on the ribbon cable must be aligned with pin-1 on both the IDE port and
the hard-drive connector.

(12). POST Code Display
This is an LED device to display the “POST” Code, the acronym of Power On Self Test. The computer
will execute the POST action whenever you power on the computer. The POST process is controlled by
the BIOS. It is used to detect the status of the computer’s main components and peripherals. Each POST
Code corresponds to different checkpoints that are also defined by the BIOS in advance. For example,
“memory presence test” is an important checkpoint and its POST Code is “C1”. When the BIOS execute
any POST item, it will write the corresponding POST Code into the address 80h. If the POST passes, the
BIOS will process the next POST item and write the next POST Code into the address 80h. If the POST
fails, we can check the POST Code in address 80h to find out where the problem lies.
This LED device also displays the “POST” Code of AC2003, an “uGuru” chipset developed exclusively
by ABIT computer.
NOTE: The decimal point lights up when executing the AC2003 POST action.
See Appendix for both AWARD and AC2003 POST Code definition.
