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.

Hardware Installation 2 34 1 33 FDC 2.3.10 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 Caution: The specification of IDE cable is maximum 46cm (18 inches), make sure your cable does not excess this length. Caution: For better signal quality, it is recommended to set far end side device to master mode and follow the suggested sequence to install your new device . Please refer to following figure. IDE2 (Secondary Channel) Slave (4th) Master (3rd) IDE1 (Primary Channel) Slave (2nd) Master (1st) 2.3.

Hardware Installation Other housings may have a 12-pin connector. If your housing has this type of connector, connect it to PANEL as shown in the figure. Make sure that the red wire of the connector is connected to +5V. 1 11 +5V 10 20 PANEL Note: If your housing comes with Turbo switch and Turbo LED connectors, you may use these connectors for Suspend switch and Green mode LED functions, respectively. Caution:.
Hardware Installation 1 2 3 4 5 6 IrDA 2.3.14 Wake-up Connector This mainboard implements special circuit to support Modem Ring-On, both Internal Modem Card (AOpen MP32) and external box Modem are supported. Since Internal Modem card consumes no power when system power is off, it is recommended to use Internal Modem. To use AOpen MP32, connect 4-pin cable from RING connector of MP32 to WKUP connector on the mainboard. Refer to Appendix B "Frequently Asked Question" for detail.
Hardware Installation 2.4 Configuring the System Memory Pin 1 of DIMM2 Pin 1 of DIMM1 Pin 1 of Bank1 This mainboard has four 72 pin SIMM sockets (Single-in-line Memory Module) and two 168 pin DIMM socket (Dual-in-line Memory Module) that allow you to install system memory from minimum 8MB up to maximum 256MB.
Hardware Installation Warning: The default memory timing setting is 60ns to obtain the optimal performance. Because of the specification limitation, 70ns SIMM is recommended to be used only for CPU external clock 60MHz. Tip: EDO DRAM is designed to improve the DRAM read performance.
Hardware Installation For double side memory module, there is one limitation. This mainboard supports only 4 RAS# (Row address latch) signals for DRAM control. They can only be occupied by one DRAM module, they can not be shared. The simple rule is: If double side module at either Bank0 or DIMM1, the other must be empty, if you use double side at Bank0, DIMM1 must be empty. If you use at DIMM1, Bank0 must be empty. Bank1 and DIMM2 have the same limitation.
Hardware Installation Warning: Do not use SIMM and SDRAM DIMM together unless you have 5V tolerance SDRAM (such as Samsung or TI). The FPM/EDO operate at 5V while SDRAM operates at 3.3V. If you combine them together the system will temporary work fine; however after a few months, the SDRAM 3.3V data input will be damaged by 5V FPM/EDO data output line. There is an important parameter affects SDRAM performance, CAS Latency Time.
Hardware Installation Warning: Do not install any SIMM that contains more than 24 chips. SIMMs contain more than 24 chips exceed the INTEL chipset driving specification. Doing so may result in unstable system behavior. Warning: Although Intel TX chipset supports x4 SDRAM chip. Due to loading issue, it is not recommended to use this kind of SDRAM. Tip: The SIMM/DIMM 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.
