Hardware Installation 2.2 Jumpers Jumpers are made by pin headers and plastic connecting caps for the purpose of customizing your hardware. Doing so requires basic knowledge of computer hardware, be sure you understand the meaning of the jumpers before you change any setting. The onboard jumpers are normally set to their default with optimized settings. On the mainboard, normally there is a bold line marked beside pin 1 of the jumper, sometimes, there are numbers also.

Hardware Installation Warning: Please make sure that you have installed CPU fan properly if Intel PP/MT-233 or AMD K6 CPU is being selected to use. It may cause your system unstable if you can not meet the heat dissipation requirement from above CPU type. It is recommended to adopt larger fan on these CPU for better air flow in the system. Please refer to AOpen 's web site (http://www.aopen.com.tw) to choose a proper CPU fan.
Hardware Installation This motherboard supports the CPU core voltage from 1.3V to 3.5V, that can be applied to the various CPU type in future.

To clear the CMOS, follow the procedures listed below: JP14 JP14 1 2 3 1 2 3 Normal Operation (default) Clear CMOS The procedure to clear CMOS: 1. Turn off the system power. 2. Locate JP14 and short pins 2-3 for a few seconds. 3. Return JP14 to its normal setting by shorting pins 1-2. 4. Turn on the system power. 5.
Hardware Installation 2.3 Connectors 2.3.1 Power Cable A standard baby AT (PS/2) power supply has two cables with six wires on each. Plug in these cables to the onboard power connector in such a way that all the black wires are in the center. The power connector is marked as PWR1 on the system board. Caution: Make sure that the power supply is off before connecting or disconnecting the power cable.
Hardware Installation 2.3.2 CPU Fan Plug in the fan cable to the two-pin fan connector onboard. The fan connector is marked CPUFAN on the system board. Attach the heatsink and fan to the CPU. Check its orientation, make sure the air flow go through the heatsink. +12V GND CPUFAN 2.3.3 PS/2 Mouse Pin 1 2 3 4 5 6 To connect a PS/2 mouse, insert the PS/2 mouse bracket connector to PS2 MS on the system board. Then plug in the PS/2 mouse cable to the mouse port on the bracket.
Hardware Installation 2.3.4 Serial Devices (COM1/COM2) To support serial devices, insert the serial device connector into the serial port on the bracket. Plug in the 10-pin flat cable to the appropriate onboard connectors. The serial port 1 connector is marked as COM1 and the serial port 2 connector is marked as COM2 on the system board. 2 1 10 9 COM2 2 1 10 9 COM1 2.3.5 USB Device (optional) You need a USB bracket to have your system to support additional USB device(s).

Hardware Installation 2.3.8 IDE Hard Disk and CD ROM This mainboard supports two 40 pin IDE connectors marked as IDE1 and IDE2. IDE1 is also known as primary channel and IDE2 as secondary channel, each channel supports two IDE devices that makes total of four devices. In order to work together, the two devices on each channel must be set differently to master and slave mode, either one can be hard disk or CDROM.
Hardware Installation IDE1 (Primary Channel) Slave (2nd) Master (1st) IDE2 (Secondary Channel) Slave (4th) Master (3rd) 2.3.9 Hard Disk LED The HDD LED connector is marked as HDD LED on the board. This connector is designed for different type of housing, actually only two pins are necessary for the LED. If your housing has four pin connector, simply plug it in. If you have only two pin connector, please connect to pin 1-2 or pin 3-4 according to the polarity.
Hardware Installation 2.3.10 Panel Connector The Panel (multifunction) connector is a 20pin connector marked as PANEL on the board. Attach the power LED, keylock, speaker, reset switch, suspend switch, and green mode LED connectors to the corresponding pins as shown in the figure. 1 11 GND KEYLOCK GND RESET POWER LED SPEAKER +5V GND NC SPEAKER Some housings have a five-pin connector for the keylock and power LED Since power LED and keylock are aligned together, you can still use this kind of connector.
Hardware Installation Note: If your housing comes with a Turbo switch, you may use this connector for Suspend switch function. Note: Pressing the Suspend switch allows you to manually force the system to suspend mode. However, this is possible only if the Power Management function in the BIOS Setup menu is enabled. Warning: If you use toggle mode Turbo switch as Suspend switch, be sure to push it twice to simulate momentary mode. Otherwise the system may hang or fail to reboot. 2.3.
Hardware Installation 2.3.12 IrDA Connector Serial port 2 can be configured to support wireless infrared module, with this module and application software such as Laplink, user can transfer files to or from laptops, notebooks, PDA and printers. This mainboard supports IrDA (115Kbps, 1 meter) as well as ASK-IR (19.2Kbps). Install infrared module onto IrDA connector and enable infrared function from BIOS setup, make sure to have correct orientation when you plug onto IrDA connector.
Hardware Installation 2.3.13 SB-LINK Pin 1 2 3 4 5 6 SB-LINK is used to connect Creative-compatible PCI sound card. If you have a Creative-compatible PCI sound card installed, it is necessary to link the card to the connector for compatibility issue under DOS environment.
Hardware Installation 2.4 Installing the System Memory Pin 1 of DIMM2 Pin 1 of DIMM1 This mainboard has four 72 pin SIMM sockets (Single-in-line Memory Module) and two 168 pin DIMM socket (Dual-inline Memory Module) that allow you to install system memory from minimum 8MB up to maximum 256MB. Pin 1 of Bank1 Pin 1 of Bank0 The SIMM supported by this mainboard can be identified by 4 kinds of factors: I.
Hardware Installation II. Speed: normally marked as -12, which means the clock cycle time is 12ns and maximum clock of this SDRAM is 83MHz. Sometimes you can also find the SDRAM marked as -67, which means maximum clock is 67MHz. III. Buffered and non-buffered: This motherboard supports non-buffered DIMMs.
Hardware Installation There is no jumper setting required for the memory size or type. It is automatically detected by the system BIOS. You can use any single side SIMM and DIMM combination list below for BANK0/BANK1 or DIMM socket, and the total memory size is to add them together. Note that because TX chipset limitation, the maximum is only 256MB.
Hardware Installation Double side module at either Bank0 or DIMM1, the other must be empty. Double side module at either Bank1 or DIMM2, the other must be empty. Following table explains more about the RAS limitation. You can see that Bank0 1st side and DIMM1 2nd side use the same RAS0#, and Bank0 2nd side and DIMM1 1st side use the same RAS1#. If you are using single side SIMM at Bank0 and single side DIMM at DIMM1, it should be no problem.
Hardware Installation There is an important parameter affects SDRAM performance, CAS Latency Time. It is similar as CAS Access Time of EDO DRAM and is calculated as number of clock state. The SDRAM that AOpen had tested are listed below. If your SDRAM has unstable problem, go into BIOS "Chipset Features Setup", change CAS Latency Time to 3 clocks.
Hardware Installation parity chips(4=4/1), total is 12 chips. 4. For 64 bit DIMM using 1M by 16 bit SDRAM, the chip count is 64/16=4 chips.
