Introduction

Introduction

Thank you for choosing the Thunderbolt system board.
The Thunderbolt is the ultimate 32-bit computing solution
for the industry's most demanding workstation applica­tions.

Based on the Intel 430TX PCIset, the Thunderbolt sup­ports the Pentium® processor with MMX™ technology,
which provides a smoother and more realistic multimedia
experience and increased 32-bit performance. Other fea­tures of the 430TX PCIset include advanced power man­agement, Universal Serial Bus support, Ultra DMA/33
hard drive protocol (up to 33MBytes/sec transfer rate),
concurrent PCI and support for different memory types,
including Synchronous Dynamic RAM and Extended Data
Out RAM.

Designed to fit into the most modern ATX form factor, the
flexible Thunderbolt also features support for PCI and ISA
slots and optional onboard sound. The ATX form factor
allows critical components such as floppy drive connectors,
chassis fan, CPU and memory to be strategically located so
that full length cards can be installed in all slots.

Micronics builds all products to exacting standards, using
the highest quality components available. We are proud
to provide this system board and believe you will be
pleased with your purchase.

be properly
grounded by
using a
special wrist
or ankle
strap, or
touch a
safely
grounded
object.

Quick Installation

We know that many experienced people prefer to read as
little of the documentation as possible. If this sounds like
you, here’s the short form to get up and running quickly.

Installing the Thunderbolt

1. Make backup copies of your installation and configu­ration diskettes.

2. Ground yourself to prevent damaging static dis­charge, then remove the Thunderbolt from its packag­ing.

3. Configure and verify the system board’s jumper set­tings (refer to Jumper Settings in Chapter 2).

4. Install the CPU and the system memory (refer to
Chapter 3).

5. Install the system board into the chassis and make all
necessary case connections.

6. Install any ISA and/or PCI add-on peripherals (refer to
Chapter 3).

7. Now you can connect any optional devices (refer to
Chapter 3).

8. Turn the computer on and press the <F2> key
when you see the screen in Figure 1.1.

9. Set the time and date. Adjust the BIOS settings to
match your configuration. If installing an IDE drive,
select the IDE device you wish to configure. Press
ENTER with Autotype Fixed Disk selected and the
BIOS will automatically configure the drive for you
(refer to Chapter 4).

10. After you have configured the Main Setup menu,
make any desired setting configurations in the Ad­vanced and Security menu. When finished, go to the
exit screen, select “Save Changes and Exit” and you
are finished with the BIOS configuration (see Chap­ter 4).

11. Install your IDE CD-ROM drive and its device
drivers (optional). Refer to Chapter 3.

12. Install the sound controller device drivers (optional).
Refer to Chapter 5.

Configuring the Thunderbolt

Although the Thunderbolt system board is packaged in
protective materials, it is important to use care while
unpacking and setting up.

Static Electricity

The Thunderbolt is shipped from the factory in an anti­static bag. To reduce the possibility of damage, it is impor­tant to neutralize any accumulated static charges on your
body before handling the board. The best way to do this
is to ground yourself using a special wrist or ankle strap.
If you do not have a strap, you should touch both of your
hands to a safely grounded object. After you have
grounded yourself, ground the Thunderbolt via the solder
pads surrounding one of its mounting holes.

Once the Thunderbolt is removed from its packaging,
place it on top of the antistatic bag. Carefully inspect the
board for damage which may have occurred during ship­ment.

Office Environment

Make sure the finished computer system is in an area with
good ventilation. The system should not be in direct
sunlight, near heaters, or exposed to moisture, dust or
dirt.

Installing the Thunderbolt

Introduction

This chapter explains how to install the Thunderbolt
system board, memory, CPU and peripherals.

WARNING: Before installing or removing any peripherals or
components, make sure you have a clear work space and that
you adhere to all anti-static precautions described in Chapter

1. Micronics recommends only trained technicians install and
configure the system board.

Damage which occurs to the board while adding or removing
peripherals or components may void the warranty. If prob­lems arise while installing peripherals, contact the computer
dealer where you purchased the peripheral or Micronics’
Technical Support Department.

System Memory Support

The flexibility of the Thunderbolt is augmented by its
support for SDRAM, EDO and FPM DRAM memory.
SDRAM memory is a new, faster memory technology that
features the ability to synchronize all operations with the
processor clock signal, which enables the coexistence of
high-performance and simple user interface.

The SDRAM memory technology extends the perfor­mance of conventional DRAM memory with its syn­chronized operation and burst mode. The result is an
improvement in memory-access performance on the Thun­derbolt system board.

Thunderbolt System Board Manual

19

Chapter 3: Installing the Thunderbolt

Installing the Thunderbolt

Installation of the Thunderbolt system board depends on
the type of case you use. The Thunderbolt is designed for
the standard ATX form factor and must be installed in an
ATX chassis.

NOTE: If you are unfamiliar with installing a system board,
Micronics highly recommends that you read the computer
user’s manual or contact your dealer’s technical support
department.

Tools Required

Micronics recommends using the following tools to install
the Thunderbolt:

Small Phillips screwdriver
Tweezers or a pair of needle-nose pliers
Tray (to hold loose screws)

Equipment Required

Micronics recommends using the following equipment with
the Thunderbolt for a typical configuration:

ATX chassis with standard hardware.
A high-quality ATX power supply capable of providing

continuous power within a 3 volt range. A power filter
may be used with a noisy AC power source.

PS/2 mouse and compatible keyboard.
Eight ohm speaker (optional)
Standard ribbon cables for internal connections.
Standard power cord (grounded).
Heat sink with cooling fan for CPU (required).

Chapter 3: Installing the Thunderbolt

System Memory

System memory is necessary to operate the Thunderbolt
system board. The Thunderbolt has two unbuffered 64-bit,
168-pin DIMM sockets for a maximum of 256 Megabytes of
RAM. Support is provided for SDRAM, EDO and FPM
DRAM memory. This chapter will explain the type of
DIMMs supported, list the rules for adding memory to the
Thunderbolt, give some examples of common memory
configurations and show how to physically install the new
DIMMs.

DIMMs Supported

For long
term
reliability,
Micronics
recom­mends using
DIMMs with
gold-plated
contacts.
The use of
tin-plated
contacts
may conflict
with the gold
alloy on the
DIMM
socket.

The Thunderbolt supports the following types of 60 or 70ns
DIMMs:

8MB (1MBx64)
16MB (2MBx64)
32MB (4MBx64)
64MB (8MBx64)
128MB (16MBx64)

Upgrading Rules

The following is a list of rules to follow when upgrading
DIMMs. If you follow these rules, your upgrade should be
trouble-free:

Use 70ns or faster DIMMs.
For EDO and FPM DRAM memory, you must use 3.3V

buffered DIMMs.
Upgrade DIMMs one bank at a time. Start with Bank

0, then Bank 1 (one DIMM per bank), adding memory
from the smallest to the largest size.

Install the different types of memory in separate banks.
(For example, install SDRAM memory in Bank 0 and
EDO memory in Bank 1.)
