FCC Notice:
Information to the User
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. Should you
experience interference to radio or television reception then the user is encouraged to try to
correct this interference by one or more of the following measures:
Re-locate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help and for additional
suggestions.
The user may find the following booklet prepared by the Federal Communications
Commission helpful:
“How to identify and Resolve Radio-TV Interference Problems.” This booklet is available

a Class B device, shielded
Introduction
1. Introduction
1.1 Overview
• The PT-7502-2 motherboard offers 64-bit programming architecture compatible with the
software base of 486 and 586 microprocessors. It is a reliable motherboard, using a Intel
i430VX chipset and a multi-layer printed circuit board. The chipset consists of a TVX
(Host Bridge & Cache Memory Controller), two TDX (Write Buffer Data Path
Controller), and 82371SB, PIIX3 (ISA Bridge & System I/O Controller).
• The PT-7502-2 is a PCI Local Bus motherboard. The four Master Mode PCI Local Bus
slots fully comply with the PCI (Peripheral Component Interconnect) Local Bus
Specification Rev. 2.1. The speed of I/O peripherals can be dramatically increased by
connecting PCI compatible interface cards to the PCI Local Bus slots on the PT-7502-2.
PINE is a member of PCI SIG (Special Interest Group).
• The PT-7502-2 is a ‘green’ design motherboard which means if there is no system activity
for a specific period of time (this period is software programmable), the PT-7502-2 will
slow down its original working frequency to zero. This will help to save power
consumption, reduce energy related pollution and protect our environment.
• The PT-7502-2 has the full complement of I/O on-board: FDC, PCI local bus Enhanced
IDE, printer port, COM ports, and dual USB port as well.
1.2 Green PC Power Management
The Green PC mode is a state that minimizes power consumption. There are two different
levels of Green PC modes :
• Standby mode. The spin motor of the HDD can be turned off.
• Inactive mode / Sleep Mode. The PT-7502-2 can stop the CPU clock under this mode.
The PT-7502-2 will be placed into Green PC mode as a result of one of the following events :
When the SMI header is connected to a momentary switch, pressing the switch will put
PT-7502-2 into Green mode.
Expiration of the internal Green PC Timer. The Green PC Timer is software programmable
which can configure in the "Power Management Setup" option of the BIOS CMOS setup. The
power management feature will be enabled as default; however, the timing may differ due to
production control. It is recommended that you re-adjust these timings according to your
personal requirements/set-up.
Through system activity monitoring and management, the PT-7502-2 will not go into Green
PC mode if any of the following activity is detected:
• PCI Master 0 activity • COM port activity
• PCI Master 1 activity • ISA master & DMA activity
• PCI Master 2 activity • IDE activity
• LPT port activity • Floppy activity
• COM port activity • Keyboard activity

Introduction
1.5 Static Electricity Precaution
Static electricity can easily damage your PT-7502-2 mainboard.
Observing a few basic precautions can help you safeguard against damage that could result in
expensive repairs. Follow the measures below to protect your equipment from static
discharge:
- Keep the mainboard and other system components in their anti-static packaging until
you are ready to install them.
- Touch a grounded surface before you remove any system component from its
protective anti-static packaging. A grounded surface within easy reach is the
expansion slot covers at the rear of the system case or any other unpainted portion of
the system chassis.
- During configuration and installation, touch a grounded surface frequently to discharge
any static electric charge that may build up in your body. Another option is to wear a
grounding wrist strap.
- When handling a mainboard or an adapter card, avoid touching its components.
Handle the mainboard and adapter cards either by the edges or by the mounting
bracket that attaches to the slot opening in the case.
