The M4Pi is an integrated system board featuring PCI Local Bus
architecture and a Mode 3 IDE controller. The PCI architecture provides high performance for Graphical User Interfaces (GUIs) and
peripherals which perform high speed data transfers, such as disks and
multimedia. It will make an excellent foundation for an advanced
personal computer or workstation.
The Micronics M4Pi system board represents Micronics' continuing
commitment to the PCI architecture. The M4Pi has been successfully
satisfying the most demanding of users for over a year. The latest
revision features Phoenix 4.04 BIOS and advanced power management.
The M4Pi's advanced power management features makes it a "GreenBoard" which means it adheres to the Environmental Protection
Agency's strict Energy Star efficiency guidelines. See Chapter 4 for
information and instructions on how to set up the "Green Section" of the
BIOS.

Configuring the M4Pi
2
Although the M4Pi system board is packaged in protective materials, it
is important to use care while unpacking and setting up.
Static Electricity
The M4Pi 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 M4Pi
via the solder pads surrounding one of its mounting holes.
Once the M4Pi 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.

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 LPM30 has completed POST; any other tone from the
speaker indicates something other than a POST error. These tones arenot 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..
