Micronics 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:
1.Make backup copies of your installation and configuration diskettes.
2.Ground yourself to prevent damaging static discharge, then remove the
M54Hi-Plus from its packaging.
3.Configure and verify the system board’s jumper settings. (See Jumper
Settings in Chapter 2)
4.Install the CPU and the system memory (Chapter 3).
5.Install the system board into the chassis and make all necessary
connections (Chapter 3).
6.Install the sound riser card and connect all sound devices (Chapter 3).
7.Install any peripherals (Chapter 3).
8.Turn the computer on and press the <F2> key when you see the screen
below:
iii
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 (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 (Chapter 4).
11. Install any CD-ROM drive and its device drivers (Chapter 5).
12. Install the sound controller device drivers (Chapter 5).

Although the M54Hi-Plus system board is packaged in protective
materials, it is important to use care while unpacking and setting up.
Static Electricity
The M54Hi-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 neutralize these static charges 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 M54Hi-Plus via the solder pads
surrounding one of its mounting holes.
Once the M54Hi-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.

System Memory, CPUs and
Peripherals
This section explains how to install the M54Hi-Plus system board,
SIMMs, CPUs, and peripherals.
Warning:
Before installing or removing any peripherals or components, make
sure you have a clear work space and adhere to all anti-static
precautions described on page 2-1. Micronics recommends only
trained technicians operate on 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
outlet where you purchased the peripheral or Micronics’ Technical
Support Department.

Micronics M54Hi-Plus System Board Manual
Installation of the M54Hi-Plus
The installation of the M54Hi-Plus system board depends on the type of case
you use. The M54Hi-Plus is an integrated baby AT size system board and
may be installed into most cases.
Prior to installing the M54Hi-Plus, make sure you have a clear work space
available and adhere to all anti-static precautions.
If you are unfamiliar with installing a system board, Micronics highly
recommends 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 M54Hi-Plus:
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 M54Hi-Plus
for a typical configuration:
Chassis with standard hardware.
A high quality power supply capable of providing continuous power
within a 5 volt range, plus or minus 5% (eg. 4.75 to 5.25). A power
filter may be used with a noisy AC power source.
AT compatible keyboard (AT Version).
PS/2 compatible keyboard (PS/2 Version).
Eight ohm speaker.
Standard ribbon cables for internal connections.
Standard power cord (grounded).
CPU heat sink with cooling fan (strongly recommended).

Installing System Memory and Add-On Peripherals
System Memory
System memory devices, commonly known as SIMMs (Single Inline Memory
Modules), are necessary to operate the M54Hi-Plus system board. The
M54Hi-Plus has four SIMM sockets and may be upgraded to 128 Megabytes
of RAM. This section will explain the type of SIMMs supported, list the
rules of adding memory to the M54Hi-Plus, give some examples of common
memory configurations, and show how to physically install the new SIMMs.
SIMMs Supported
The M54Hi-Plus supports the following 72 pin, 60ns or 70ns SIMMs:
4MB (1Mx36)
8MB (2Mx36)
16MB (4Mx36)
32MB (8Mx36)
Note:
For long term reliability, Micronics recommends using SIMMs with tin-plated
contacts. The use of gold-plated contacts may conflict with the tin-alloy on
the SIMM socket.
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.
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.

Common Memory Configurations
The following table (Table 3-1) lists the most common memory configurations. The M54Hi-Plus will accept any combination of SIMMs as long as the
rules in the previous section are followed.
