Chapter 2 Hardware Installation This chapter gives you a step-by-step procedure on how to install your system. Follow each section accordingly. Caution: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component. 1. Do not remove a component from its protective packaging until you are ready to install it. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection. 2. 2-1 Hardware Installation 2.1 Jumpers and Connector Locations The following figure shows the locations of the jumpers and connectors on the system board: USB PS2 MS KB1 BIOS I S A 3 I S A 2 I S A 1 PWR1 FDC COM2 PRINTER COM1 P C I 4 P P C C I I IrDA 3 2 P C I 1 S I M M 1 S I M M 2 S I M M 3 S I M M 4 D I M M 1 D I M M 2 SB-LINK IDE1 IDE2 PiiX4 HDD LED SW1 JP14 TX PANEL FAN JP12 JP4 JP5 JP6 2-2 Hardware Installation Jumpers SW1: JP4,JP5,JP6: JP12: JP14: DIP Switch for CPU voltage and clock ratio CPU external (bus) clock I/O Voltage Clear CMOS Connectors KB1: PWR1: PS2 MS: USB: COM1: COM2: FDC: PRINTER: IDE1: IDE2: FAN: IrDA: HDD LED: PANEL: SB-LINK: AT keyboard connector AT (PS/2) power connector PS/2 mouse connector USB connector COM1 connector COM2 connector Floppy drive connector Printer connector IDE1 primary channel IDE2 secondary channel CPU fan connector IrDA (Infrared) connector HDD LED connector Front panel (Multifunction) connector Creative PCI sound card connector 2-3 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. If we connect (short) plastic cap to pin 1 and 2, we will say set it at 1-2, and when we say jumper is open, that means no plastic cap connected to jumper pins. 1 2 1 2 1 2 3 1 2 3 Open Short Jumper set at 1-2 Jumper set at 2-3 2-4 Hardware Installation 2.2.1 Setting the CPU Voltage S4 ON OFF OFF ON OFF OFF OFF S5 ON ON OFF OFF OFF ON ON S6 ON ON ON OFF OFF OFF OFF S7 ON ON ON ON ON OFF ON S8 OFF OFF OFF OFF OFF OFF ON Vcore 3.52V 3.45V 3.2V 2.9V 2.8V 2.2V 1.8V SW1 is used to select CPU core voltage (Vcore) and ratio, there are totally eight switches on the DIP.

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. Tip: Normally, for single voltage CPU, Vcpuio (CPU I/O Voltage) is equal to Vcore, but for CPU that needs dual voltage such as PP/MT (P55C) or Cyrix 6x86L, Vcpuio is different from Vcore and must be set to Vio (PBSRAM and Chipset Voltage). The single or dual voltage CPU is automatically detected by hardware circuit. Tip: For supporting more different CPUs in future, this motherboard uses five switchs to specify Vcore. There are 32 settings totally, and the range is from 1.3V to 3.5V.
