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.

the CPU release lever.  
3. Align the Backplate Standoffs with the  
mounting holes on motherboard. Position the  
backplate onto motherboard.  
4. Place the Retention Frame onto the  
motherboard and align it with the Backplate  
Standoffs.  
5. Place heatsink on top of CPU, and make sure  
the heatsink fits properly on the retention  
frame.  
6. Hook both sides of the Spring Clip onto the  
Mounting Tabs of Retention Frame. Tighten  
screws until the Spring Clip is fully installed.  
7. Attach the fan connector of Heatsink & Fan  
Assembly with the CPU-FAN connector on

(11). IDE Connectors  
This motherboard provides two IDE ports to connect up to four IDE drives at Ultra DMA mode by Ultra  
ATA/66 ribbon cables. Each cable has 40-pin 80-conductor and three connectors, providing two hard  
drives connection with motherboard. Connect the single end (blue connector) at the longer length of  
ribbon cable to the IDE port on motherboard, and the other two ends (gray and black connector) at the  
shorter length of the ribbon cable to the connectors on hard drives.  
If you want to connect two hard drives together through one IDE channel, you must configure the second  
drive to Slave mode after the first Master drive. Please refer to the drives’ documentation for jumper  
settings. The first drive connected to IDE1 is usually referred to as “Primary Master”, and the second  
drive as “Primary Slave”. The first drive connected to IDE2 is referred to as “Secondary Master” and the  
second drive as “Secondary Slave”.  
Keep away from connecting one legacy slow speed drive, like CD-ROM, together with another hard drive  
on the same IDE channel; this will drop your integral system performance.

(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.

(15). System Management Bus Headers  
This header is reserved for system management bus (SM bus). The SM bus is a specific implementation  
of an I2C bus. I2C is a multi-master bus, which means that multiple chips can be connected to the same  
bus and each one can act as a master by initiating a data transfer. If more than one master simultaneously  
tries to control the bus, an arbitration procedure decides which master gets priority.

Troubleshooting (Need Assistance?)  
H-1  
Appendix H. Troubleshooting (Need Assistance?)  
Q & A:  
Q: Do I need to clear the CMOS before I use a new motherboard to assemble my new computer  
system?  
A: Yes, we highly recommend that you clear the CMOS before installing a new motherboard. Please  
move the CMOS jumper from its default 1-2 position to 2-3 for a few seconds, and then back. When  
you boot up your system for the first time, follow the instructions in the user's manual to load the  
optimized defaults.  
Q: If my systems hang when I update the BIOS or set the wrong CPU parameters, what should I  
do?  
A: Whenever you update the BIOS or if the system hangs due to wrong CPU parameters setting, always  
clear CMOS jumper before booting up again.  
Q: Why the system failed to boot up and nothing was displayed on the screen after I did some  
over-clocking or non-standard settings inside the BIOS? Is the motherboard dead? Do I need to  
return it to where I bought from or go through an RMA process?  
A: It should not cause hardware or permanent damage to motherboard when BIOS settings were  
changed from default to over-clocking or non-standard status.  
We suggest the following three troubleshooting methods to discharge CMOS data, recover the  
hardware default status, and then make the motherboard working again. No need to bother returning  
the motherboard to where you bought from or go through an RMA process.  
Step 1. Switch off the power supply unit and then switch it on again after one minute. If there is no  
power switch on the power supply unit, disconnect its power cord for one minute and then  
connect it back.  
Press and hold the <Insert> key on the keyboard, press the power-on button to boot up  
system. If it works, loose the <Insert> key and hit <Del> key to enter the BIOS setup page to  
do the correct settings.  
If the situation remains the same, repeat the procedures in Step 1 for three times, or try Step  
2.  
Step 2. Switch off the power supply unit or disconnect the power cord. Open the chassis cover.  
Locate the CCMOS jumper near the button battery. Change the jumper position from default  
1-2 to 2-3 for one minute to discharge the CMOS data, and then put it back to default 1-2  
position.  
Close the chassis and switch on the power supply unit or plug in the power cord. Press the  
power-on button to boot up system. If it works, hit <Del> key to enter the BIOS setup page  
to do the correct settings.  
If the situation remains the same, try Step 3.  
Step 3. The same procedure as Step 2, but in the meantime of discharging the CMOS data, pull out  
ATX power connectors from motherboard and remove the button battery during CMOS  
discharging.

Q: How can I get a quick response to my request for technical support?  
A: Be sure to follow the guidelines as stated in the “Technical Support Form” section of this manual.  
If you have a problem during operation, in order to help our technical support personnel quickly  
determine the problem with your motherboard and give you the answers you need, before filling in  
the technical support form, eliminate any peripheral that is not related to the problem, and indicate it  
on the form. Fax this form to your dealer or to the company where you bought the hardware in order  
to benefit from our technical support. (You can refer to the examples given below)  
Example 1:  
With a system including: motherboard (with CPU, DRAM, COAST...) HDD, CD-ROM, FDD, VGA  
CARD, MPEG CARD, SCSI CARD, SOUND CARD, etc. After the system is assembled, if you  
cannot boot up, check the key components of the system using the procedure described below. First  
remove all interface cards except the VGA card and try to reboot.  
If you still cannot boot up: Try installing another brand/model VGA card and see if the system will  
start. If it still does not start, note the VGA card model, motherboard model, Bios identification  
number, CPU on the technical support form (refer to main instructions), and describe the problem in  
the problem description space provided.  
If you can boot up: Insert the interface cards you have removed back into the system, one by one  
and try to start the system each time you insert a card, until the system will not start. Keep the VGA  
card and the interface card that caused the problem inserted on the motherboard, remove any other  
cards or peripheral, and start again. If you still cannot start, note the information related to both cards  
in the add-on Card space provided, and don’t forget to indicate the motherboard model, version,  
BIOS identification number, CPU (refer to main instructions), and give a description of the problem.  
Example 2:  
With a system including the motherboard (with CPU, DRAM, COAST...) HDD, CD-ROM, FDD,  
VGA CARD, LAN CARD, MPEG CARD, SCSI CARD, SOUND CARD, after assembly and after  
having installed the Sound Card Driver, when you restart the system, when it runs the Sound Card  
Driver, it resets automatically. This problem may be due to the Sound Card Driver. During the  
Starting DOS… procedure, press SHIFT (BY-PASS) key, to skip CONFIG.SYS and  
AUTOEXEC.BAT; edit CONFIG.SYS with a text editor, and in function the line that loads the  
Sound Card Driver, add a remark REM, in order to disable the Sound Card Driver. See the example  
below.  
CONFIG.SYS:  
DEVICE=C:\DOS\HIMEM.SYS  
DEVICE=C:\DOS\EMM386.EXE HIGHSCAN  
DOS=HIGH, UMB  
FILES=40  
BUFFERS=36  
REM DEVICEHIGH=C:\PLUGPLAY\DWCFGMG.SYS  
LASTDRIVE=Z  
Restart the system. If the system starts and does not reset, you can be sure that the problem is due to  
the Sound Card Driver. Write down the Sound Card model, motherboard model, BIOS identification  
number on the technical support file (refer to main instructions), and describe the problem in the  
space provided.  
We will show you how to fill the “Technical Support Form”.

7. RMA Service. If your system has been working but it just stopped, but you have not  
installed any new software or hardware recently, it is likely that you have a defective  
component. Please contact the reseller from whom you bought the product. You should be  
able to get RMA service there.  
8. Reporting Compatibility Problems to ABIT. Because of tremendous number of email  
messages we receive every day, we are forced to give greater weight to certain types of  
messages than to others. For this reason, any compatibility problem that is reported to us,  
giving detailed system configuration information and error symptoms will receive the  
highest priority. For the other questions, we regret that we may not be able to reply  
directly. But your questions may be posted to the Internet news group in order that a  
larger number of users can have the benefit of the information. Please check the news  
group from time to time.
