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. Ground yourself to prevent damaging static discharge, then remove
the M5Pi from its packaging.
2. Configure and verify the system board’s jumper settings. (See
Jumper Settings in Chapter 2)
3. Install the CPU and the system memory (Chapter 3).
4. Install the system board into the system case and make all necessary
case connections.
5. Install any ISA and PCI peripherals (Chapter 3).
6. Turn the computer on and press <Ctrl>, <Alt>, and <s>
simultaneously after 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

iv
to configure. Press <Enter> with Auto 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).

1Introduction
Congratulations for choosing the Micronics M5Pi! The M5Pi is a high-
performance system board designed to be a foundation for serious
computer applications.
The M5Pi is a 60/66 MHz Pentium based board and is one of the most
powerful Intel-based products on the market.
The M5Pi comes with many built in features. These include support for
four IDE hard drives, support for two floppy drives, a bi-directional
parallel port, and two high speed serial ports.
Micronics builds all products to exacting standards, using the highest
quality components available. We are proud to provide this system
board and hope it brings you years of reliable service.

Features
The M5Pi includes the following features:
mPentium processor support for 60MHz or 66MHz processors.
mTwo 32-bit PCI slots, four ISA slots, and one shared (PCI or ISA) slot.
m256K of L2 write-back cache.
mSupports up to 128MB of on-board system memory.
mPrimary PCI Mode 3 IDE controller (supports two drives).
mSecondary ISA IDE controller (supports two drives).
mFloppy controller for two floppy drives (Supports 2.88MB, 1.44MB,
1.2MB, 720K, and 360K floppy drives).
mTwo high speed NS16550 compatible serial ports.
mBi-directional parallel port that is EPP and ECP compatible (see
Specifications).

2Configuring the M5Pi
Although the M5Pi system board is packaged in protective materials, it
is important to use care while unpacking and setting up.
Static Electricity
The M5Pi 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 M5Pi
via the solder pads surrounding one of its mounting holes.
Once the M5Pi 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 M5Pi, System
Memory, CPUs and Peripherals
This section explains how to install the M5Pi 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 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.

Installation of the M5Pi
The installation of the M5Pi system board depends on the type of case you
use. The M5Pi is a Baby AT size system board and you should be able to
install it in most cases.
Prior to installing the M5Pi, 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 M5Pi:
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 M5Pi 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..
mPS/2 compatible keyboard (PS/2 version).
mAT-compatible keyboard (AT version).
mEight ohm speaker (included with most chassis).
mStandard ribbon cables for internal connections.
mStandard power cord (grounded).
mHeat sink with cooling fan (required).

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 M5Pi system board. The M5Pi has
four SIMM sockets and can be upgraded to 128 Megabytes of RAM. This
section will explain the type of SIMMs supported, list the rules of adding
memory to the M5Pi, give some examples of common memory configurations,
and show how to physically install the new SIMMs.
SIMMs Supported
The M5Pi supports the following 72 pin, 60 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 of 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:
mUse 70ns or faster SIMMs. Anything slower will not keep up with
the Pentium processor.
mUpgrade SIMMs two at a time. These SIMMs must be the same size
and preferably from the same manufacturer. To add 16MB of
memory to the system board, install two 8MB SIMMs into bank 0
and bank 1.
mWhen installing SIMMs, start with ‘bank 0’ and work your way up
(0,1,2,3).
