Micronics Quick Installation
We know that many experienced people prefer to read as little of the documen-
tation 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
M4Pi 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
case connections.
6. Install any peripherals (Chapter 3).
7. Turn the computer on and press the <F2> key when you see the screen
below:

8. 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. (See Chapter 4)
9. 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). The system is
ready to be loaded with software and used.

1Introduction
The M4Pi is an integrated system board featuring PCI Local Bus
architecture and a Mode 3 IDE controller. The PCI architecture pro-
vides high performance for Graphical User Interfaces (GUIs) and
peripherals which perform high speed data transfers, such as disks and
multimedia. It will make an excellent foundation for an advanced
personal computer or workstation.
The Micronics M4Pi system board represents Micronics' continuing
commitment to the PCI architecture. The M4Pi has been successfully
satisfying the most demanding of users for over a year. The latest
revision features Phoenix 4.04 BIOS and advanced power management.
The M4Pi's advanced power management features makes it a "Green
Board" which means it adheres to the Environmental Protection
Agency's strict Energy Star efficiency guidelines. See Chapter 4 for
information and instructions on how to set up the "Green Section" of the
BIOS.

2Configuring the M4Pi
Although the M4Pi system board is packaged in protective materials, it
is important to use care while unpacking and setting up.
Static Electricity
The M4Pi 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 M4Pi
via the solder pads surrounding one of its mounting holes.
Once the M4Pi 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 ventila-
tion. The system should not be in direct sunlight, near heaters, or
exposed to moisture, dust, or dirt.

3Installing the M4Pi, System
Memory, CPUs, and
Peripherals
This section explains how to install the M4Pi system board, SIMMs,
CPUs, 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 on page 2-1. Micronics recommends that only
trained technicians operate on the system board. Damage which
occurs to the board while adding or removing peripherals or compo-
nents may void the warranty.
If problems arise while installing peripherals, contact the computer
outlet where you purchased the peripheral or Micronics’ Technical
Support Department.
3-1

Installation of the M4Pi
The installation of the M4Pi system board depends on the type of chassis you
use. The M4Pi is an integrated baby AT size system board and can be installed
in most chassis.
Prior to installing the M4Pi, 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 recom-
mends 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 M4Pi:
mSmall Phillips screwdriver.
mTweezers or a pair of needle-nose pliers.
mTray (to hold loose screws).
Equipment Required
Micronics recommends using the following equipment with the M4Pi for a
typical configuration:
mChassis with standard hardware.
mA 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.
mAT compatible keyboard (AT Version).
mPS/2 compatible keyboard and mouse (PS/2 Version).
mEight ohm speaker.
mStandard ribbon cables for internal connections.
mStandard power cord (grounded).
mCPU heat sink.

System memory devices, commonly known as SIMMs (Single Inline Memory
Modules), are necessary to operate the M4Pi system board. The M4Pi has
four SIMM sockets and can be upgraded to 128 Megabytes of RAM. This
section will explain the type of SIMMs supported, list the memory configura-
tions supported, and show how to physically install the new SIMMs.
SIMMs Supported
The M4Pi supports the following 72 pin, 60 or 70ns SIMMs:
4MB (1Mx36)
8MB (2Mx36)
16MB (4Mx36)
32MB (8Mx36)
