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 Jumper and Connector Locations The following figure shows the locations of the jumpers and connectors on the system board: PS2 MS KBC USB KB 1 PWR 1 I S A 3 I S A 2 I S A 1 PCI 4 PCI 3 PCI 2 PCI 1 S I M COM2 M 4 PRINTER S I M M 3 S I M M 2 SD II MM MM 11 COM1 FDC1 IDE2 JP3 JP4 IDE1 JP25 JP14 JP20 BIOS RTC JP18 FAN HDD LED IrDA JP11 JP9 JP7 PANEL JP8 JP12 JP1 JP2 JP10 2-2 Hardware Installation Jumpers: JP1,JP2: JP3,JP4: JP7: JP8: JP9,JP10, JP11,JP12 JP14: JP18: JP20: JP25: Connectors: KB1: PWR1: PS2 MS: USB: COM1: COM2: FDC1: PRINTER: IDE1: IDE2: FAN: IrDA: HDD LED: PANEL: CPU frequency ratio select CPU external (bus) clock select CPU core voltage setting (Vcore) I/O voltage setting (Vio) CPU type (Single/Dual voltage, Vcpuio) selection For clearing CMOS Enable/disable onboard super I/O controller Enable/disable onboard PS/2 mouse DIMM memory type select 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 2-3 Hardware Installation 2.2 Jumper Settings Board jumpers are made of pin headers and plastic connecting caps. These are included in the mainboard design to enable you to customize your hardware. The onboard jumpers are normally set to its default and optimum setting. Be sure you have basic knowledge of computer hardware and understand the function of the jumper before you change any setting. Pin 1 of a jumper is indicated by a bold line on the mainboard. You may also find number indications on the board to specify the proper configuration of the jumper. To set a jumper, simply connect the plastic cap to the required pins. For example, to set a jumper to 1-2, place the plastic cap on pins 1-2 of the jumper. An OPEN setting means that no plastic cap connected to the 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 JP7 1-2 3-4 5-6 7-8 9-10 11-12 CPU Core Voltage (Vcore) 3.45V (Intel P54C or IDT C6) 3.52V (Cyrix or AMD K5) 2.9V (K6-166/200 or M2) 2.8V (MMX P55C) 3.2V (AMD K6-233) 2.1V (Reserved) JP7 is used to select CPU core voltage (Vcore), normally it is set to default 3.45V for INTEL Pentium P54C. It must be changed if you have CPU with different core voltage, such as INTEL PP/MT MMX (P55C), AMD K5/K6 and Cyrix 6x86, refer to the CPU specification for more details.

Please make sure that you have installed CPU fan properly if Intel PP/MT-233 or AMD K6-200/233 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. 2-5 Hardware Installation JP8 1-2 3-4 I/O Voltage (Vio) 3.45V (default) 3.52V JP8 is reserved for testing purposes only. This jumper enables you to set the voltage of the onboard chipset and PBSRAM (Vio). For dual-voltage CPU, JP8 also functions as CPU I/O voltage (Vcpuio) controller. The default voltage setting is 3.45V.

These jumpers are actually for selecting the CPU I/O voltage (Vcpuio). Normally, for single-voltage CPU such as P54C, AMD K5 and Cyrix 6x86, Vcpuio is equal to Vcore. However, for CPU that needs dual voltage such as PP/MT (P55C) and Cyrix 6x86L, Vcpuio is different from Vcore and must be set to Vio.

Unlike the Intel P54C, their internal core frequency is not exactly equal to P-rating marked on the CPU. For example, the AMD PR133 frequency is 100MHz, but its performance is almost equal to Intel P54C 133MHz. The Intel VX chipset does not support CPU with 55MHz and 75MHz external bus clock; thus, this motherboard cannot support Cyrix P133+ and C6150. 2-11 Hardware Installation 2.2.3 Disabling the Onboard Super I/O Controller JP18 1-2 2-3 Onboard Super I/O Enabled (default) Disabled The board is default by the manufacturer to enable the onboard Super I/O controller. In case you wish to use an external I/O controller, you need to disable the onboard I/O before the external I/O card functions. To disable, set jumper JP18 to 2-3.
