MSM855/HLV/B/B2 Detailed Manual V1.0A
ROM-BIOS Sockets
An EPROM socket with 8bit wide data access normally contains the board's AT compatible ROM-BIOS. The
socket takes an E82802AC8 EPROM (or equivalent) device. The board's wait-state control logic
automatically inserts four memory wait-states in all CPU accesses to this socket. The ROM-BIOS sockets
occupy the memory area from C0000H through FFFFFh; however, the board's ASIC logic reserves the entire
area from C0000h through FFFFFh for onboard devices, so that this area is already usable for ROM-DOS
and BIOS expansion modules. Consult the appropriate address map for the MICROSPACE MSM855 ROMBIOS sockets.
5.7.
CMOS RAM Map
Systems based on the industry-standard specification include a battery backed Real Time Clock chip. This
clock contains at least 64Bytes of non-volatile RAM. The system BIOS uses this area to store information
including system configuration and initialization parameters, system diagnostics, and the time and date. This
information remains intact even when the system is powered down.
The BIOS supports 128Bytes of CMOS RAM. This information is accessible through I/O ports 70h and 71h.
CMOS RAM can be divided into several segments:

 Locations 00h - 0Fh contain real time clock (RTC) and status information

 Locations 10h - 2Fh contain system configuration data

 Locations 30h - 3Fh contain System BIOS-specific configuration data as well as chipset-specific
information

 Locations 40h - 7Fh contain chipset-specific information as well as power management configuration
parameters
The following table provides a summary of how these areas may be further divided.

EEPROM Saved CMOS Setup
The EEPROM has different functions, as listed below:

 Backup of the CMOS-Setup values.

 Storing system informations like: version, production date, customisation of the board, CPU type.

 Storing user/application values.
The EEPROM will be updated automatically after exiting the BIOS setup menu. The system will also operate
without a CMOS battery. While booting up, the CMOS is automatically updated with the EEPROM values.
Press the ESC-key while powering on the system before the video shows the BIOS message and the CMOS
will not be updated. This is helpful if incorrect parameters are stored in the EEPROM and the setup of the
BIOS does not start.
If the system hangs or a problem appears, the following steps must be performed:
1. Reset the CMOS-Setup (to reset the CMOS, disconnect the battery for at least 10 minutes).
2. Press ESC until the system starts up.
3. Enter the BIOS Setup:
a. load DEFAULT values (F9)
b. enter the settings for the environment
c. exit the setup (F10)
4. Restart the system.
The user may access the EEPROM through the INT15 special functions. The system information is read-only
and uses the SFI functions. Please refer to the driver/software/BIOS manual 855_BIOS, the chapter on
Special Peripherals / Configurations, the Special Function Interface (SFI).
5.8.1.
EEPROM Memory for Setup
The EEPROM is used for setup and configuration data, stored as an alternative to the CMOS-RTC.
Optionally, the EEPROM setup driver may update the CMOS RTC, if the battery is running down and the
checksum error would appear and stop the system. The capacity of the EEPROM is 2 kByte.

5.14. SpeedStep Performance Control
The Pentium-M improved the SpeedStep mechanism by adding a third power scheme in addition to the lowpower and the full-performance modes. This new mode is called adaptive mode, and allows the frequency
and voltage to switch according to the CPU activity. The CPU uses a low-power mode by default, but when
its activity increases, it switches itself very quicky into full-performance mode. This new power scheme is
very pleasant to use, because it allows full CPU speed only when needed. Of course, power consumption
depends on the CPU activity, and the more the CPU is used, the more it consumes power.

Notes:
1. The shaded area denotes power or ground signals.
2. The KEY pins are to guarantee proper module installation. Pin-A1 will be removed and the female
side plugged for 5.0V I/O signals and Pin-D30 will be modified in the same manner for 3.3V I/O. It is
recommended that both KEY pins (A1 and D30) be electrically connected to GND for shielding.

* J16 Default Setting: closed by a jumper between Pins 1 and 2. If this jumper is closed until the main supply
powers up, the computer system will start with a boot sequence.
If you want to use a push button to start the system:
If this jumper is open until the main supply powers up, the board does not start. You must connect a
push button (Main Button) to Pins 1-2. After pushing the main button, the board will start. (If you press
the Main Button for more than 4 seconds, the power will be switched off.)
** if you want to use the PWRBTN signal (i.e., in W2k or XP) you must connect another push button to Pins
2-3 of the J16 jumper to shut down the Windows OS by pressing the push button.
Note…
After the system is shut down with the Power Button, to restart the system the Main Button
(connected to Pins 1-2) must be used.
The PWRBTN signal is low active and internally pulled to 3.3V.

The following figures show the location of all jumper blocks on the MSM855 board. The numbers shown in
the figures are silk screened on the board so that the pins can easily be located. This chapter refers to the
individual pins for these jumpers. The default jumper settings are written in bold.
Be careful: some jumpers are soldering bridges; you will need a miniature soldering station with a vacuum
pump.
Settings written in bold are defaults!

Maximum length for the IDE cable is 30cm.
Attention!
Check the Pin 1 marker of the cable and the connector before you power-on. Refer to the
technical manual of the installed drives because a wrong cable will immediately destroy the
drive and/or the MICROSPACE MSM945 board. In this case the warranty is void! Without
the technical manual you may not connect this type of drive.
The 44pin IDE connector on the drives is normally composed of the 44 pins, 2 open pins and
4 test pins, 50 pins in total. Leave the 4 test pins unconnected.

Attention!

 Do not short circuit these signal lines.

 Never connect any pins on the same plug or to any other plug on the MICROSPACE

10.THERMAL SPECIFICATIONS
10.1. Thermal Analysis for Case Integration
Since the integrated heat sink is uni-directional, the airflow must be exactly in the direction of the heat rails. If
possible, mount the board vertically, so that the heat rails are up/down. In this case, the self produced airflow
is about 3m/sec.
Pay particular attention when mounting the PC-product in a fully enclosed case/box. The thermal energy will
be stored in the inner room of this environment.
If the case has a fan:

 The hot air must be exchanged with cool air from outside using a filtered fan.

 The hot air must be cooled with a heat exchanger.
If the case has no fan or opening to exchange the hot air:

 The heat sink of the CPU must be mounted directly to a heat sink integrated in the case. The thermal
energy does not go through the air; the heat will be conducted directly through the alloy of the heat
sink to the outside.

 Diminish the thermal energy production by reducing the CPU performance, i.e. by using the 600MHz
clock only.

Step 1:
Put the passive heat sink onto the SM855.
Step 2:
Attach the heat sink with 3 screws.
Screw Type:
Cylinder hexagon socket type screw M2x6mm

 Used for connecting the ATX–compatible toggle switch (momentary close between Pins 1 and 2).

 If this jumper is closed until the main supply powers up, the computer system starts by booting.

 If this jumper is open until the main supply power up, then Pin1 (ATX-switch) must be tied to the
ground (Pin 2) to start the computer system (this is the ATX-function).
