SYSTEM OVERVIEW
The
PT-6IFA
Pentium Pro PCI Local Bus system board is an ATX form-factor
system board. It is designed based on the Intel 82440FX PCIset system chipset and
Winbond I/O chipset. It built-in two channel PIO and Bus Master Enhanced PCI IDE
ports, one Floppy Disk control port, two high speed Serial ports (UARTs) and one
multimode Parallel port and also supports PS/2 mouse, IR and USB ports. It is designed
to fit a high performance, Pentium Pro Processor 150 MHz up to 266 MHz based
solution for high-end and true GREEN-PC computer systems.
The Pentium Pro Processor is a 64-bit processor with RISC technology, which offers
several key features such as built-in 256KB/512KB L2 cache, 12-stage superpipeline
architecture, out of order execution .... etc, in order to optimize its capabilities and
performances, the Pentium Pro Processors require 32-bit Operating Systems (such
Windows NT and OS/2) and applications.
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.
A.
FEATURES
The PT-6IFA system board contains the following features:
Supports wide range Pentium Pro family CPUs from 150 MHZ through 266
MHz , fully IBM PC/AT compatible system board with ISA Bus and PCI Local
Bus.
Built-in 3 set voltage regulator circuits to support all low-voltage components
include CPU, chipset ..., so that no VRM (Voltage Regulator Module) is needed.
DRAM Memory : Supports fast page mode (FPM), Extended Data Out (EDO)
and Burst Extended Data Out (BEDO) memory. Supports
