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. Ground yourself to prevent damaging static discharge, then remove the
Mpower 4 plus 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. (See Chapter 3)

4. Install the system board into the system case and make all of the necessary
case connections.

5. Install any peripherals (see Chapter 3). It is best not to put the computer
cover on until you have verified the system is working properly.

6. Turn the computer on. The computer goes through a self-test and the
following screen appears. If Setup detects any configuration errors, the
message "Press <F1> to continue (boot up) or <F2> to run the Setup
procedure" will appear. Press the <F2> key and make any necessary
configurations.

iii

If the Power-Up screen does not appear, but the DOS prompt does (ie.,
A:\ or C:\), press the <Ctrl>, <Alt>, and <Esc> keys simultaneously to
begin the Setup procedure.

7. 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. Select Auto Config and the BIOS will automatically
configure the drive for you. (See Chapter 4)

8. After all configurations have been made, press <Esc> to exit. Then press
<F4> to save the configuration and reboot. (See Chapter 4)

Introduction

1

The Mpower 4 plus is an integrated, low-profile, LPX system board,
featuring VESA Local bus architecture, a Mode 3 IDE controller, and
64-bit graphics. The Micronics Mpower 4 plus system board represents
Micronics' third generation of VESA Local Bus system boards and
makes an excellent foundation for an advanced personal computer or
workstation.

Micronics is a forerunner in VESA Local Bus technology. The VESA
Local Bus Architecture provides high performance for Graphical User
Interfaces (GUIs) and peripherals that perform high speed data transfers,
such as disks and multimedia.

Setting Up the Mpower 4 plus

2

Although the Mpower 4 plus system board is packaged in protective
materials, it is important to use care while unpacking and setting it up.

Static Electricity

The Mpower 4 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 (any silver part of the case should
suffice). After you have grounded yourself, ground the Mpower 4 plus
via the solder pads surrounding one of its mounting holes.

Once the Mpower 4 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.

Accelerator Software

The Mpower 4 plus comes standard with the ATI mach64 video chip on
board. The mach64 chip is a 64-bit graphics accelerator offering
superior video performance. Certain utilities must be run before using
the mach64. For optimal performance, install the utilities completely.

Preparation

Make sure that no hardware (internal modems, Fax cards, or LAN cards)
are using addresses between the range of 2E0 to 2EF, such as COM 4
(2E8). If they are occupied, change the device(s) to a different range
outside of 2E0 through 2EF.

Make sure LAN cards, scanner cards and other adapters are not using
memory addresses between C0000 and C7FFF. Check and record the
amount of memory installed on the system board.

Review the CONFIG.SYS file to determine if a Memory Manager
Device driver is loaded. Memory Manager Device drivers (for example;
EMM386, QEMM, and 386MAX) may interfere with the mach64
installation. Install the Memory Manager after the mach64 is com­pletely loaded.

Installing Graphics Accelerator Software

Troubleshooting

Listed below are several checks you can make to help determine the cause of
any problems:

System Lockup

M If you are using a memory manager such as QEMM or 386MAX, you

need to modify the command line in the CONFIG.SYS file so the
address of the graphics card video BIOS, C0000-C7FFF, is excluded.
For example, add “X=C000-C7FF” to the command line

M Remove all unnecessary boards.

M Disable shadow RAM.

M Ensure the board is seated correctly and the card has been installed

using proper utilities.

M Try the card in a different system and reset to factory defaults using

the INSTALL program. If the card works in another system, the
problem is likely due to incorrect configuration.

Test Patterns OK; Applications Do Not Sync

M The wrong monitor type has been selected. Change the settings in the

INSTALL program.

Window Driver Not Installing Properly

M Windows must be running in 386 Enhanced Mode. Incompatible

commands or options within CONFIG.SYS may prevent Windows
from starting in enhanced mode. If this occurs, remove the offending
driver or reinstall the memory manager software.

AutoCAD Driver Not Installing Properly

M If using a 386, ensure AutoCAD has been configured for the

appropriate ADI driver. The protected mode driver requires extended
memory.

Beep Codes

B

Beep codes are a series of beeps sent through the speaker which indicate
a problem during the Power On Self Test (POST). If text appears on the
video screen, the Mpower 4 plus has completed POST; any other tone
from the speaker indicates something other than a POST error. These
tones are not described in Table B-1.

The beep error codes are a series of three sets of beeps. The duration of
the beep tones are constant, but the length of the pauses between the
beeps varies. For example: a 1-3-3 beep code will sound like one beep,
a pause; three beeps consecutively, another pause; and then three more
beeps.

One beep code is often misunderstood. If a video card is not installed or
is failing, the system board will generate a long-short-long-short beep
code. This is often interpreted as a 1-2-1 beep code. But POST errors
always vary in the length of the pause and not the duration of the beep
tone.

Another way of identifying a POST error is to use a device called a
POST card. This peripheral card is inserted into one of the ISA slots
and has an LED (or LCD) read out showing the contents of port 80h.

The following table provides a list of all beep codes and probable
causes.
