Hardware Setup	2-1

Chapter 2. Hardware Setup

Before 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 become damaged.

2-1. Install The Motherboard

Most computer chassis have a base with many mounting holes to allow the motherboard to be securely attached, and at the same time, prevent the system from short circuits. There are two ways to attach the motherboard to the chassis base:

1.use studs, or

2.use spacers

In principle, the best way to attach the board is to use 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.

2-3. Install System Memory

This motherboard provides four 240-pin DIMM slots for Single/Dual Channel DDR2 667 memory modules with memory expansion size up to 8GB.

•To reach the optimum performance in dual-channel configurations, install identical DDR2 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 DDR2 memory modules.

•Due to chipset limitation, 128MB DIMM modules or double-sided x16 memory chips are not supported.

There are several methods of different DDR2 configurations depending on how the DIMMs are populated on each system memory channel:

•[Single Channel]: only one channel is populated.

Method		Channel A			Channel B
	DIMM1		DIMM2	DIMM3		DIMM4

(13). 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 AC2005, an “uGuru” chipset developed exclusively by ABIT computer.

NOTE: The decimal point lights up when executing the AC2005 POST action.

See Appendix for both AWARD and AC2005 POST Code definition.
