PT-5IH
SYSTEM BOARD
INTRODUCTION
1. INTRODUCTION
1.1
SYSTEM OVERVIEW
The
PT-5IH
Pentium PCI Local Bus system board is designed based on the Intel 82430HX PCIset system
chipset and Winbond (or SMC, UMC) 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) and one multimode Parallel
prot and also supports IR and USB ports. It is designed to fit a high performance, Pentium 75 MHz to 200 MHz
(ideally) based solution for high-end and true GREEN-PC computer systems.
This system board supports the Peripheral Component Interconnect (PCI) Local Bus standard (PCI Spec. Rev.
2.1 compliant). It not only breaks through the I/O bottlenecks of the traditional ISA main board, but also
provides the performance needs for networking and multi-user environments.
1.2
FEATURES
The PT-5IH system board contains the following features:
Pentium P54C/P54CT/P54CS/P55C, Cyrix 6x86 & AMD 5
k
86 based, PC/AT compatible
system board with ISA Bus and PCI Local Bus.
Supports the most part of "586" level CPUs designed by Intel, Cyrix and AMD.
Built-in 2 sets voltage regulator circuit to support multi-spec. CPU I/O voltage (includes
Standard, VR and VRE specification) and CPU CORE voltage (+2.5V DC and +2.8V DC).
