M55Hi-Plus System Board Manual

Introduction

Thank you for choosing the M55Hi-Plus system board.
The high-performance M55Hi-Plus provides the latest
enhancements in system board technology for the world’s
most advanced workstation applications.

Based on the Intel 430HX (Triton II) chipset, the M55Hi­Plus provides enhanced PCI throughput and perfor­mance as well as support of Universal Serial Bus (USB).
The USB interface has a maximum bandwidth of 12Mbps
and can connect as many as 127 devices to a host system.
USB supports both standard devices that operate at the
full 12-Mbps rate and low-end devices that use only a 1.5­Mbps subchannel.

The M55Hi-Plus is designed to fit into the most modern
ATX form factor. The ATX form factor allows critical
components such as floppy and IDE connectors, chassis
fan, CPU and memory to be strategically located so that
full length cards can be used in all slots. The M55Hi-Plus
combined with the Intel 430HX chipset makes this
system board the ultimate desktop workstation solution.

The M55Hi-Plus comes with many features. These in­clude support for Extended Data Out (EDO) and Fast
Page Mode (FPM) DRAM memory, Error Checking
Correction (ECC), the Phoenix Plug and Play BIOS and
an optional feature for integrated 16-bit sound.

For energy efficiency, full support is provided for the
Green PC specification. 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.

Configuring the M55Hi-Plus

Although the M55Hi-Plus system board is packaged in
protective materials, it is important to use care while
unpacking and setting up.

Static Electricity

The M55Hi-Plus 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 M55Hi-Plus via the sol­der pads surrounding one of its mounting holes.

Once the M55Hi-Plus 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 M55Hi-Plus

Introduction

This section explains how to install the M55Hi-Plus
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
Section 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 M55Hi-Plus is augmented by its
support for Error Checking and Correction (ECC),
Extended Data Out (EDO) DRAM memory and Fast
Page Mode (FPM) DRAM memory. The M55Hi-Plus
allows vast memory capability without worrying about
memory errors. It does this by providing ECC which
enables parity checking to detect and correct memory
errors.

EDO memory is designed to keep data available to the
processor for an extended period of time. The EDO
memory support extends the performance of conven­tional DRAM memory. The result is an improvement in
memory-access performance on the M55Hi-Plus system
board.

Section 3: Installing the M55Hi-Plus

System Memory

System memory devices, commonly known as SIMMs,
are necessary to operate the M55Hi-Plus system board.
The M55Hi-Plus has four 32/36-bit SIMM sockets and
can be upgraded to 256 Megabytes of RAM. In addition,
support is provided for Error Checking (ECC), Extended
Data Out (EDO) DRAM memory and Fast Page Mode
(FPM) DRAM memory.

This section will explain the type of SIMMs supported,
list the rules for adding memory to the M55Hi-Plus, give
some examples of common memory configurations and
show how to physically install the new SIMMs.

SIMMs Supported

The M55Hi-Plus supports the following types of 60 or
70ns SIMMs:

4MB (1MBx32/36)
8MB (2MBx32/36)
16MB (4MBx32/36)
32MB (8MBx32/36)
64MB (16MBx32/36)

Upgrading Rules

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

Use 70ns or faster SIMMs.
Upgrade SIMMs one bank at a time. Each bank must

contain two SIMMs of the same size and preferably
from the same manufacturer. For example, to add
16MB of memory to the system board, install two
8MB SIMMs into the same bank.

When installing SIMMs, fill bank 0, then bank 1.
