Configuring the M5Pi
2
Although the M5Pi system board is packaged in protective materials, it
is important to use care while unpacking and setting up.
Static Electricity
The M5Pi 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 M5Pi
via the solder pads surrounding one of its mounting holes.
Once the M5Pi 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 ventila-
tion. The system should not be in direct sunlight, near heaters, or
exposed to moisture, dust, or dirt.

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 M5Pi system board. The M5Pi has
four SIMM sockets and can be upgraded to 128 Megabytes of RAM. This
section will explain the type of SIMMs supported, list the rules of adding
memory to the M5Pi, give some examples of common memory configurations,
and show how to physically install the new SIMMs.
SIMMs Supported
The M5Pi supports the following 72 pin, 60 or 70ns SIMMs:
4MB (1Mx36)
8MB (2Mx36)
16MB (4Mx36)
32MB (8Mx36)
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 of 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:
m
m
Use 70ns or faster SIMMs. Anything slower will not keep up with
the Pentium processor.
Upgrade SIMMs two at a time. These SIMMs must be the same size
and preferably from the same manufacturer. To add 16MB of
memory to the system board, install two 8MB SIMMs into bank 0
and bank 1.
m
When installing SIMMs, start with ‘bank 0’ and work your way up
(0,1,2,3).

keyboard during boot. If set for NOT INSTALLED, the system will ignore
any keyboard errors and always attempt to boot. Set this for INSTALLED
unless using the system board in an application which does not require a
keyboard.
Setting the CMOS Extended Screen
You can toggle between the Main screen and the Extended screen (Figure 4-3)
using the PgUp and PgDn key.

Serial Port B
Serial Port 2 may be set for COM2 (default), COM4, or may be disabled. Be
sure this setting does not conflict with any other peripherals.
Parallel Port
The parallel port may be set for LPT1 (default), LPT2, or may be disabled. Be
sure this setting does not conflict with any other peripherals.
Secondary IDE
The ISA IDE controller can be set to ENABLED or DISABLED.
Onboard Floppy
The On Board Floppy controller can be set to ENABLED or DISABLED.
Swap Floppies
This category can be set to remap the floppy drives. It can be set for NOR-
MAL (default) or SWAPPED. For normal operation, Drive A: and Drive B:
work normally. When “Swapped” is selected, Drive A: becomes Drive B:, and
Drive B: becomes Drive A:.
Boot Sequence
This category selects the order the system searches for a boot disk and can be
set for “A: First” or “C: First.”
Cache State
This category allows you to enable both the internal and the external cache,
enable the internal cache only, or disable both caches. For optimal perfor-
mance, select BOTH.
Note:
External cache must be installed in order to select BOTH.
1st PCI Device
This selection allows you to set the IRQ of the 1st PCI device to IRQ9, IRQ11,
or IRQ15. The next IRQ will automatically be assigned to the next peripheral.
(eg. If slot 0 is empty, slot 1 has a SCSI controller, and slot 2 has a network
card, setting 1st PCI Device for IRQ9 will assign the SCSI controller to IRQ9
and the network card to IRQ11.)
Note:
Not all PCI peripherals require an IRQ and most video cards do not. Even if
slot 0 had a video card installed in the above example, the system would still
assign IRQ9 to the SCSI controller.

The BIOS Setup Utility
System BIOS
The System BIOS Option allows you to Shadow, Shadow & Cache, or Disable
the BIOS Shadow on the system board. Choosing SHADOWED copies the
system’s BIOS into RAM for faster execution. Choosing SHADOWED &
CACHED caches the shadowed system BIOS for even higher performance.
This allows you to take advantage of the high-speed 32-bit bus and the 70
nanosecond RAM. Use the <+/-> key to toggle between the options.
Video BIOS
The Video BIOS Option allows you to Shadow, Shadow & Cache, or Disable
the BIOS Shadow on the system board. Choosing SHADOWED copies the
system’s video BIOS into RAM for faster execution. Choosing SHADOWED
& CACHED caches the shadowed video BIOS for even higher performance.
Use the <+/-> key to toggle between the options. The System BIOS Shadow
option must be set to SHADOW or SHADOW & CACHE before enabling the
Video BIOS Shadow options.
Option ROM
Some peripheral cards such as low-priced SCSI controllers and network
adapters which do not have their own BIOS require this feature. Check the
documentation of your peripheral cards to see if they need this feature.

Beep Codes
B
Beep codes are a series of beeps sent through the speaker which indicate
a problem during POST. If text appears on the video screen, the M5Pi
has completed POST; any other tone from the speaker indicates some-
thing 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. With no video card installed, or
if the video card 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.

Limited Warranty
Except as described below, Micronics warrants the products to be free from
defects in material and workmanship in normal use for a period of one (1) year
from date of purchase. Should any product fail to perform according to this
warranty at any time during the warranty period, except as provided below,
Micronics or its authorized service centers will, at Micronics’ option, repair or
replace the product at no additional charge.
The warranty does not cover loss or damage which occurs in shipment or
which is due to: (1) improper installation or maintenance, misuse, neglect or
any cause other than ordinary commercial application, including without
limitation, accidents or acts of God; (2) adjustment, repair, or modification by
other than a Micronics authorized service center; (3) improper environment,
excessive or inadequate heating or air conditioning, or electrical power
failures, surges or other irregularities; (4) any statement about the product
other than those set forth in this warranty; or (5) nonconformity to models or
samples shown to the purchaser. Any models or samples were for the sole
purpose of suggesting the character of the product and are not intended to
form the basis of the bargain.
A receipt or copy of the invoice with the date of purchase from a Micronics
reseller is required before any warranty service can be rendered. Service can
be obtained by calling Micronics for a Return Merchandise Authorization
(RMA) Number.
The RMA Number should be prominently displayed on the outside of the
shipping carton of the returned product. Returned product should be shipped
prepaid or hand carried to Micronics. The purchaser assumes risk of loss or
damage in transit, and unless otherwise agreed to in writing by Micronics, will
pay inbound shipping charges.

repair or replace at Micronics’ option, but if for any reason that remedy should
fail of its essential purpose, the exclusive remedy of the purchaser shall then
be actual damages up to amounts paid for the defective product by the
purchaser. This limited warranty shall be deemed to “fail of its essential
purpose” if, after repeated efforts, Micronics is unable to make the product
operate as warranted. Micronics’ liability for damages to the purchaser for
any cause whatsoever; regardless of the form of action and whether in contract
or in tort, shall be limited to the purchase price in effect when the cause of
action arose for the product that is the basis of the claim.
