Micronics Quick Installation
We know many experienced people prefer to read as little of the documenta-
tion 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
M4Pe 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. (See Chapter 3)
5. Install the motherboard into the system case and make all of the neces-
sarycase connections.
6. Install any ISA, PCI, and EISA add-on peripherals. (See Chapter 3)
Do not replace the computer cover until you have verified the
system is working properly.
7. Turn the computer on and press the <Ctrl>, <Alt>, and <Esc> keys
simultaneously when you see the screen below:

8. Set the time and date. Adjust the BIOS settings to match what is
installed in your system. If installing an IDE drive, select the IDE
device you wish
to configure. Press <Enter> with AUTO CONFIG 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, press the <F4> key (Save Values, Exit
SETUP, and Reboot), and you are finished with the BIOS configuration.
(See Chapter 4)
10. Insert the MCS EISA Configuration Utility into Drive A or Drive B and
type:
a:cf <Enter>
or
b:cf <Enter>
Follow the directions and install the necessary drivers for your EISA
peripherals. (See Chapter 5)

2Configuring the M4Pe
Although the M4Pe system board is packaged in protective materials, it
is important to use care while unpacking and setting up.
Static Electricity
The M4Pe 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. Then ground the M4Pe via the solder pads surround-
ing one of its mounting holes.
Once the M4Pe 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.

3Installing the M4Pe, System
Memory, CPUs and Peripherals
This section explains how to install the M4Pe 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 (see 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.
3-1

Installation of the M4Pe
The installation of the M4Pe system board depends on the type of case you
have. Prior to installing the M4Pe, make sure you have a clear work space
available and adhere to all anti-static precautions.
If you are unfamiliar with installing a motherboard, it is highly recommended
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 M4Pe:
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 M4Pe 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 added for areas with noisy transmission.
mAT compatible keyboard.
mEight ohm speaker.
mStandard ribbon cables for internal connections.
mShielded AC power cable (grounded).
mHeat sink (for DX2 and DX4 processors).
Micronics M4Pe System Board Manual

3-3
Installing System Memory and Add-On Peripherals
System Memory
The M4Pe will accomodate a maximum of 128MB using on-board 256Kx36
(1MB) through 8Mx36 (32MB) SIMMs.
The SIMMs
The M4Pe has four 36-bit (72-pin) SIMM sockets that must be filled two at a
time. Fill bank 0 and bank 1 first. Then fill bank 2 and bank 3, if necessary.
The SIMMs must be rated at 70ns or faster. Use the following guidelines
when installing additional memory:
mBanks 0 and 1 must be filled with identical SIMMs. When install-
ing different size SIMMs, install the larger size SIMMs into banks 0 and
one and the smaller size into banks 2 and 3.
mBanks 2 and 3, if filled, must contain the same size SIMM.
mAll memory must be either all parity SIMMs or all non-parity
SIMMs.
Note:
For long term reliability, Micronics recommends using SIMMs with gold-
plated contacts. The use of tin-plated contacts may conflict with the gold-
plated contacts of the SIMM socket.
Installing the SIMMs
Perform the following steps to install the SIMMs:
1. Hold the SIMM so the NOTCHED edge points towards the CPU
socket.
2. Insert the SIMM at a 45 degree angle.
3. Gently push the SIMM to an upright position until it “snaps” into
place.
