Unpacking the Mainboard & Static Electricity Precautions This mainboard package contains the following items: 1. 2. 3. The i430TX Mainboard This UserÕs Guide Cables: 2 serial port ribbon cables/brackets; 1 parallel ribbon cable/bracket; 1 floppy ribbon cable; 1 IDE ribbon cable 4. 5. 6. The Device Driver for this mainboard ATX FORM CARD (optional) Sound & Game ribbon cables/bracket This mainboard is easily damaged by static electricity. Follow the precautions below while unpacking or installing the mainboard. 1. Do not remove the mainboard from its original package until you are ready to install it. Before handling the mainboard, ground yourself by grasping an unpainted portion of the systemÕs metal chassis. 2. Introduction 3. 5 Frequently ground yourself to discharge any static electric charge that may build up in your body while working on installation and/or configuration. Remove the mainboard from its anti-static packaging and place it on a grounded surface, component side up. Handle the mainboard by its edges or by the mounting bracket to avoid touching its components. Check the mainboard for damage. If any integrated circuit appears loose, press carefully to seat it firmly in its socket. Do not apply power if the mainboard appears damaged. If there is damage to the board contact your dealer immediately. 4. 5. 6. 7. Chapter 2 Hardware Configuration Before installing the mainboard into the system chassis, you may find it convenient to first configure the mainboardÕs hardware. This chapter describes how to set jumpers and install memory modules, and where to attach components. 8 Chapter 2 Mainboard Component Locations 1 12 12 2 1 8 7 J2 Sound Pro J1 PS1 COM1 COM2 PRN1 1 1 1 1 IO Chip SL1 SL2 1 SL3 KBD1 IDE2 IDE1 PWR1 PCI4 JP1A JP1B Game Sound PCI3 10 1 PCI2 PCI1 CPU FAN 1 1 JP9 19 RST TB-LED J7 SUS-SW Keylock 2 20 HDD-LED Figure 2Ð1.

A description of each connector follows. See Figure 2Ð1 for the location of the connectors on the mainboard. Note: Make sure that the power is turned off before making any connection to the board. PWR1 ­ AT Power Supply Connectors The power supply connectors are two six-pin male header connectors. Plug the dual connectors from the power directly onto the board connectors. Most of power supply have two leads and each lead has six wires. Two of which are black, orient the connectors so that the black wires are in the middle.
