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. 2.

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.

It must be changed if you have CPU with different core voltage, such as INTEL PP/MT (P55C), AMD K5/K6 and Cyrix 6x86, refer to the CPU specification for more details.
Hardware Installation JP9 Close JP10 Open JP11 Close Open Close Open CPU Type (Vcpuio) Single voltage CPU Vcpuio = Vcore (default) Dual voltage CPU Vcpuio = Vio (PP/MT P55C) JP11 5 6 Set the jumper JP9, JP10 and JP11 according to the type of CPU. They are actually the selection of CPU I/O Voltage (Vcpuio). Normally, for single voltage CPU, Vcpuio is equal to Vcore, but for CPU that needs dual voltage such as PP/MT (P55C), Cyrix 6x86L, Vcpuio must be set to Vio, and it is different from Vcore.

Hardware Installation 2.4 Configuring the System Memory This mainboard has four 72 pin SIMM sockets (Single-in-line Memory Module) that allow you to install system memory from minimum 4MB up to maximum 256MB. Pin 1 of SIMM The SIMM supported by this mainboard can be identified by 4 kinds of factors: ♦ Size: single side, 1Mx32 (4MB), 4Mx32 (16MB), 16Mx32 (64MB), and double side, 1Mx32x2 (8MB), 4Mx32x2 (32MB), 16Mx32x2 (128MB).
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 combination list below for, and the total memory size is to add them together, the maximum is 256MB.
Hardware Installation Warning: Do not install any SIMM that contains more than 24 chips. SIMMs contain more than 24 chips exceed the chipset driving specification. Doing so may result in unstable system behavior. Tip: The SIMM chip count can be calculated by following example: 1. For 32 bit non-parity SIMM using 1M by 4 bit DRAM chip, 32/4=8 chips. 2. For 36 bit parity SIMM using 1M by 4 bit DRAM chip, 36/4=9 chips. 3.
