Although the M6Pi system board is packaged in protective
materials, it is important to use care while unpacking and setting up.
Static Electricity
The M6Pi 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 M6Pi via the solder pads surrounding one of its mounting
holes.
Once the M6Pi 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.

Installing System Memory and Add-On Peripherals
System Memory
System memory devices, commonly known as SIMMs (Single Inline Memory
Modules), are necessary to operate the M6Pi system board. The M6Pi has
four SIMM sockets and may be upgraded to 256 Megabytes of RAM. This
section will explain the type of SIMMs supported, list the rules of adding
memory to the M6Pi, give some examples of common memory configurations,
and show how to physically install the new SIMMs.
SIMMs Supported
The M6Pi supports the following 72 pin, 60ns or 70ns SIMMs:
4MB (1Mx36 or 1Mx32)
8MB (2Mx36 or 2Mx32)
16MB (4Mx36 or 4Mx32)
32MB (8Mx36 or 8Mx32)
64MB (16Mx36 or 16Mx32)
Note:
For long term reliability, Micronics recommends using SIMMs with tin-plated
contacts. The use of gold-plated contacts may conflict with the tin-alloy on
the SIMM socket.
Upgrading Rules
The following is a list of rules to follow when upgrading SIMMs. If you
follow these rules, your upgrade should be trouble-free:
❏ Use 70ns or faster SIMMs.
❏ Upgrade SIMMs one bank at a time. All SIMM sockets must contain
SIMMs of the same size and preferably from the same manufacturer. To
add 16MB of memory to the system board, install two 8MB SIMMs into
the same bank.
❏ When installing SIMMs, fill bank 0, then bank 1.

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 M6Pi 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..
