Configuring the M55Hi-Plus
Although the M55Hi-Plus system board is packaged in
protective materials, it is important to use care while
unpacking and setting up.
Static Electricity
The M55Hi-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. After you have
grounded yourself, ground the M55Hi-Plus via the solder pads surrounding one of its mounting holes.
Once the M55Hi-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.

turning on the computer, make sure all cables are correctly connected and all jumpers are correctly set.
It is recommended you keep the computer cover off the
first time you boot the system. This will make it easier to
correct any difficulties that might arise.
Initial Boot Up
Power up the M55Hi-Plus. If the system does not properly boot, check all your cables and peripherals for bad
connections. You may also get beep codes or error
messages. If this occurs, consult Appendices B and/or C
for a guide to possible solutions.
After the system properly boots, it is ready to be configured. The following information explains the proper
procedures for BIOS configuration.
Setup
The Setup program is used to configure the computer’s
BIOS (Basic Input/Output System). The computer’s
BIOS is responsible for configuring the system board and
providing hardware information to the operating system.
In order for the computer to run properly, run the Setup
procedure after first installing the system board and
whenever you make a hardware change to the system.

Appendix C: Beep and POST Codes
Appendix
C
Beep and POST Codes
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 M55Hi-Plus has completed POST; any other tone
from the speaker indicates something other than a
POST error. These tones are not described in the tables
on the following pages.
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 1-33 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 tables list all beep codes and POST
routines.

Appendix E: Updating the System BIOS
Appendix
E
If you
encounter
any
problems
during this
process, or
if you have
questions
about the
procedure,
please call
Technical
Support.
Updating the System BIOS
The Micronics system boards are designed so that the
BIOS can be reprogrammed using a BIOS file. You can
easily FLASH a BIOS by following the steps below:
1) After downloading the appropriate BIOS file from
our BBS or Website, extract it to a bootable MSDOS 6.X or Windows 95 diskette.
2) If you are using MS-DOS 6.X, reboot your system
with the bootable diskette in the A: drive. To make
sure a clean DOS environment is loaded, press the
F5 key while "Starting MS-DOS" is displayed. After
the system has rebooted, the cursor will appear at
the A:\> prompt.
3) If you are using Windows 95, press F8 when you see
"Starting MS Windows 95." Select the option "Safe
Mode Command Prompt."
4) Now you can run the FLASH utility. The filename
will be either "FSH" (or FSH20, FSH20G, etc.) or
"PHLASH." Type this filename at the A:\> prompt
(but don’t include its extension), followed by a space
and the BIOS ROM image’s filename. This file will
be included in the download and has a file length of
about 131K. For example, to update the M55HiPlus to BIOS version 02, you would type:
PHLASH M55HIPLS.02P [ENTER]
5) After the update process is completed, turn off the
system.
6.) Turn the system back on and verify that the new
BIOS version appears on the screen.
NOTE: If the BIOS is somehow erased or doesn’t seem
to accept the upgrade, you can have your original BIOS
chip reprogrammed manually by Technical Support.
There is a $29.95 fee for this service, which includes
M55Hi-Plus System Board Manual
65
Appendix E: Updating the System BIOS
shipping charges to send your FLASH EPROM chip back
to you. Also, a preprogrammed FLASH EPROM chip can
be purchased from Technical Support for $50.00. Overnight shipping costs an additional $10.00. (Price and
availability subject to change.)
If you prefer to send your system board in for the upgrade,
the RMA department offers this service free of charge if
your system board is under warranty.
