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.

the Sound Controller Drivers
This chapter explains how to install a CD-ROM drive and the sound
drivers necessary to operate the sound controller on the M54Hi-Plus.
Prior to installing any drivers, follow the instructions in Chapter 3 on
how to install the sound riser card and how to connect devices to the
sound controller.
About Device Driver s
Device drivers are necessary for the computer system to communicate
with devices such as CD-ROM drives, sound controllers, graphics
adapters, or any devices which are not natively supported by the system
BIOS.
Once started, device drivers remain active in the background of the
computer system. Usually a device driver is added to the CONFIG.SYS
file, the AUTOEXEC.BAT file, or both.

Micronics M54Hi-Plus System Board Manual
Installing a CD-ROM Drive
Micronics recommends the installation of an IDE CD-ROM. If you are
installing a CD-ROM drive these instructions will help you, but also refer to
the documentation which accompanied your CD-ROM drive. Before starting
the setup and installation, make sure your computer is off and the power cord
is disconnected from the wall outlet. Your CD-ROM drive kit should contain
the following items for a successful installation:
CD ROM Drive with optional slide rails.
Interface Cable.
Audio Cable.
Install the CD-ROM hardware as recommended by the CD-ROM manufacturer. Follow the steps below for help on installing the CD-ROM audio cable.
Installing the cable:
1. Connect the ribbon cable as described in the CD-ROM’s documentation,
making sure the red stripe on the cable is aligned with pin 1 of the
connectors.
2. Connect the audio cable to the CD-ROM drive's audio connector.
3. Connect the other end of the audio cable to the MPC-2 compatible CDROM audio connector on the M54Hi-Plus system board (Figure 3-10).
4. Install the CD-ROM device drivers. CD-ROM drives require device
drivers to access the drive and are generally provided by the manufacturer of the CD-ROM drive. Usually one device driver is added to the
CONFIG.SYS file and one to the AUTOEXEC.BAT file.
5. Now, you are now ready to setup the sound controller. Follow the
“Hardware Installation” section in Chapter 3 and the “Installing the
Sound Controller Drivers” section at the end of this chapter.
5-2
Installing the Sound Drivers
Installing the Sound Controller Drivers
If you are installing a CD-ROM drive, it is recommended you install it before
setting up the sound controller. See Installing a CD-ROM Drive on the
previous page.
1. Follow the instructions in Chapter 3 on installing the sound riser card
and connecting devices.
2. If you previously installed another sound card, remove it and all associated files from your AUTOEXEC.BAT and CONFIG.SYS files.
3. Start your computer system.
4. Insert the sound controller driver disk into your floppy drive.
5. From the DOS prompt (C:\), type:
a:install
6. Follow the on-screen instructions and the install program automatically
copies the drivers to your hard drive.
7. Once the software is copied, the install program automatically updates
your CONFIG.SYS and AUTOEXEC.BAT files.
8. After the installation is complete, reboot your system and your sound
controller is ready to use.

Beep and POST Codes
Beep and POST 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 M54Hi-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 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 POST routines..
