NOTE
The “LOAD SETUP DEFAULTS” function loads the default settings directly from BIOS
default table, these default settings are the best-case values that will optimize system
performance and increase system stability. This function will be necessary when you
receive this system board, or the system CMOS data is corrupted.
By pressing “Enter” key. The SETUP default values will be loaded. (Please refers to the
Chapter 5 AWARD BIOS SETUP procedures in this manual.)

1. INTRODUCTION
1.1 SYSTEM OVERVIEW
ThePT-5ITBPentium PCI Local Bus system mainboard is designed based on AT
form-factor on the Intel 82430TX PCIset system chipsets and Winbond I/O chipset, which
built-in two channels PIO and Bus Master Enhanced PCI IDE port, one Floppy Disk
control port, two high speed Serial ports (UARTs), one multimode Parallel port, one PS/2
keyboard port, one PS/2 mouse port, one IR port, two USB ports, and support PC97
specification. It is designed to fit a high performance, Pentium 75 MHz to 233 MHz based
solution for high-end and true GREEN-PC computer systems.
This system board supports the Peripheral Component Interconnect (PCI) Local Bus
standard (PCI Specification Rev. 2.1 compliant). It not only breaks through the I/O
bottlenecks if the traditional ISA mainboard, but also provides the performance needs for
networking and multi-user environments.

PT-5ITB SYSTEM BOARD HARDWARE SETUP

4. HARDWARE SETUP
This chapter explains how to configure the mainboard hardware. When you are installing
the mainboard, you will have to make jumper settings and cable connections. Refer to this
chapter whenever you install or reconfigure your system.
4.1 UNPACKING
The system board package should contain the following parts :
The PT-5ITB system board.
OPERATION MANUAL.
Cable set for IDE and I/O device.
The mainboard contains electric sensitive components which can be easily damaged by
static electricity, so the mainboard should be left in its original packing until it is installed.
Unpacking and installation should be done on a grounded anti-static mat. The operator
should be wearing an anti static wristband, grounded at the same point as the anti-static
mat.
Inspect the mainboard carton for obvious damage. Shipping and handling may cause
damage to your board. Be sure there are no shipping and handling damages on the board
before proceeding.
After opening the motherboard carton, extract the mainboard and place it only on a
grounded anti-static surface with the component side up. Inspect the board again to see
whether there is any damage.
Press down on all of the socket IC‘s to make sure that they are properly seated. Do this
only with the board placed on a firm flat surface.
4.2 HARDWARE CONFIGURATION
Before the system board is ready for operating, the hardware must be configured to make
sure it will work properly with different environment. To configure the PT-5ITB system
board is a simple task, only a few jumpers, connectors, cables and sockets needs to be
selected and installed. (For the detailed locations of each component please refer to the
“system board layout figure” which appears in page 3-1.)

4.2.2 JUMPERS
A jumper is two, three or more pins which may or may not be covered by a plastic
connector plug (mini-jumper). A jumper is used to select different system options. Please
make sure all jumpers at correct position before this system board used.
(A) JP1, JP2, JP3, JP4, JP5, JP6 CPU type selection (For Jumpers Setting)
NOTE :
When JP1, JP2, JP3, JP4, JP5, JP6 are empty, then this mainboard is jumperfree for CPU
type selection, so you must enter the system BIOS to setup the correct CPU type. Please
you refer to this manual the page 5-6, the 5.6 CHIPSET FEATURES SETUP item.
