COMe-bSC2 / Introduction

2 Introduction

2.1 Product Description

In 2011, Intel® introduced its first quad core CPU suitable for the COM Express® platform. With the quad-core CPU Core™
i7-2715QE and the dual-core CPUs Core™ i3/i5/i7, COM Express® reaches ground-breaking performance values: both for
CPU and GPU rankings. With various CPUs COMe-bSC# serves your individual performance needs, starting with a 1.0 GHz
version Celeron® 807UE.

Kontron's COMe-bSC# is available as COM Express® basic form factor (125x95mm) for Pin-out Type 2 (COMe-bSC2) and
Pin-out Type 6 (COMe-bSC6) with or without ECC DDR2 memory support.

2.2 Naming clarification

COM Express® defines a Computer-On-Module, or COM, with all components necessary for a bootable host computer,
packaged as a super component.

» COMe-bXX# modules are Kontron's COM Express® modules in basic form factor (125mm x 95mm)

» COMe-cXX# modules are Kontron's COM Express® modules in compact form factor (95mm x 95mm)

» COMe-mXX# modules are Kontron's COM Express® modules in mini form factor (55mm x 84mm)

The product names for Kontron COM Express® Computer-on-Modules consist of a short form of the industry standard
(COMe-), the form factor (b=basic, c=compact, m=mini), the capital letters for the CPU and Chipset Codenames (XX) and
the pin-out type (#) followed by the CPU Name.

2.3 Understanding COM Express® Functionality

All Kontron COM Express® basic and compact modules contain two 220pin connectors; each of it has two rows called Row
A & B on primary connector and Row C & D on secondary connector. COM Express® Computer-on-modules feature the
following maximum amount of interfaces according to the PICMG module Pin-out type:

COMe-bSC2 / Introduction

2.4 COM Express® Documentation

This product manual serves as one of three principal references for a COM Express® design. It documents the
specifications and features of COMe-bSC2. Additional references are available at your Kontron Support or at PICMG®:

» The COM Express® Specification defines the COM Express® module form factor, pin-out, and signals. This document

is available at the PICMG® website by filling out the order form.

» The COM Express® Design Guide by PICMG® serves as a general guide for baseboard design, with a focus on

maximum flexibility to accommodate a wide range of COM Express® modules.

Some of the information contained within this product manual applies only to certain
product revisions (CE: xxx). If certain information applies to specific product revisions (CE:
xxx) it will be stated. Please check the product revision of your module to see if this
information is applicable.

2.5 COM Express® Benefits

COM Express® modules are very compact, highly integrated computers. All Kontron COM Express® modules feature a
standardized form factor and a standardized connector layout which carry a specified set of signals. Each COM is based on
the COM Express® specification. This standardization allows designers to create a single-system baseboard that can
accept present and future COM Express® modules.

The baseboard designer can optimize exactly how each of these functions implements physically. Designers can place
connectors precisely where needed for the application on a baseboard designed to optimally fit a system’s packaging.

A single baseboard design can use a range of COM Express® modules with different sizes and pin-outs. This flexibility can
differentiate products at various price/performance points, or when designing future proof systems that have a built-in
upgrade path. The modularity of a COM Express® solution also ensures against obsolescence when computer technology
evolves. A properly designed COM Express® baseboard can work with several successive generations of COM Express®
modules.

A COM Express® baseboard design has many advantages of a customized computer-board design and, additionally,
delivers better obsolescence protection, heavily reduced engineering effort, and faster time to market.

Power Supply

The COMe-bSC2 supports a power input from 8.5V - 18V (20V@nonECC). The supply voltage is applied through the VCC pins
(VCC) of the module connector.

Power Button (PWRBTN#)

The power button (Pin B12) is available through the module connector described in the pinout list. To start the module via
Power Button the PWRBTN# signal must be at least 50ms (50ms ≤ t < 4s, typical 400ms) at low level (Power Button Event).

Pressing the power button for at least 4seconds will turn off power to the module (Power Button Override).

Power Good (PWR_OK)

The COMe-bSC2 provides an external input for a power-good signal (Pin B24). The implementation of this subsystem
complies with the COM Express® Specification. PWR_OK is internally pulled up to 3.3V and must be high level to power on
the module.

Reset Button (SYS_RESET#)

The reset button (Pin B49) is available through the module connector described in the pinout list. The module will stay in
reset as long as SYS_RESET# is grounded. If available, the BIOS setting for “Reset Behavior” must be set to “Power Cycle”.

Modules with Intel® Chipset and active Management Engine do not allow to hold the
module in Reset out of S0 for a long time. At about 10s holding the reset button the ME will
reboot the module automatically

SM-Bus Alert (SMB_ALERT#)

With an external battery manager present and SMB_ALERT# (Pin B15) connected the module always powers on even if
BIOS switch “After Power Fail” is set to “Stay Off”.

3.10 MTBF

The following MTBF (Mean Time Before Failure) values were calculated using a combination of manufacturer’s test data, if
the data was available, and the Telcordia (Bellcore) issue 2 calculation for the remaining parts.
The calculation method used is “Telcordia Issue 2 Method 1 Case 3” in a ground benign, controlled environment (GB,GC).
This particular method takes into account varying temperature and stress data and the system is assumed to have not
been burned in.
Other environmental stresses (extreme altitude, vibration, salt water exposure, etc) lower MTBF values.

System MTBF (hours): 222498 @ 40°C (w/PCB)

Fans usually shipped with Kontron Europe GmbH products have 50,000-hour typical
operating life. The above estimates assume no fan, but a passive heat sinking arrangement
Estimated RTC battery life (as opposed to battery failures) is not accounted for in the above
figures and need to be considered separately. Battery life depends on both temperature
and operating conditions. When the Kontron unit has external power; the only battery
drain is from leakage paths.

3.13 Thermal Management, Heatspreader and Cooling Solutions

A heatspreader plate assembly is available from Kontron Europe GmbH for the COMe-bSC2. The heatspreader plate on top
of this assembly is NOT a heat sink. It works as a COM Express®-standard thermal interface to use with a heat sink or
external cooling devices.

External cooling must be provided to maintain the heatspreader plate at proper operating temperatures. Under worst­case conditions, the cooling mechanism must maintain an ambient air and heatspreader plate temperature on any spot of
the heatspreader's surface according the module specifications:

» 60°C for commercial grade modules

» 75°C for extended temperature grade modules (E1)

» 85°C for industrial temperature grade modules (E2/XT)

The aluminum slugs and thermal pads or the heat-pipe on the underside of the heatspreader assembly implement thermal
interfaces between the heatspreader plate and the major heat-generating components on the COMe-bSC2. About 80
percent of the power dissipated within the module is conducted to the heatspreader plate and can be removed by the
cooling solution.

You can use many thermal-management solutions with the heatspreader plates, including active and passive approaches.
The optimum cooling solution varies, depending on the COM Express® application and environmental conditions. Active
or passive cooling solutions provided from Kontron Europe GmbH for the COMe-bSC2 are usually designed to cover the
power and thermal dissipation for a commercial grade temperature range used in a housing with proper air flow.

COMe-bSC2 / Features and Interfaces

4 Features and Interfaces

4.1 S5 Eco Mode

Kontron’s new high-efficient power-off state S5 Eco enables lowest power-consumption in soft-off state – less than 1 mA
compared to the regular S5 state this means a reduction by at least factor 200!

In the “normal” S5 mode the board is supplied by 5V_Stb and needs usually up to 300mA just to stay off. This mode allows
to be switched on by power button, RTC event and WakeOnLan, even when it is not necessary. The new S5 Eco mode
reduces the current enormous.

The S5 Eco Mode can be enabled in BIOS Setup, when the BIOS supports this feature.

Following prerequisites and consequences occur when S5 Eco Mode is enabled

» The power button must be pressed at least for 200ms to switch on.

» Wake via Power button only.

» “Power On After Power Fail”/“State after G3”: only “stay off” is possible

COMe-bSC2 / Features and Interfaces

4.2 Rapid Shutdown

Overview

For “R” or the “RXT” version of the COMe-bSC2, Kontron has implemented a rapid shutdown function. It works as follows:

1) An active-high shutdown signal is asserted by the COM Express Eval Type 2 carrier board via pin C67 of the COM Express
connector. The characteristics of the shutdown signal are as follows:

» Amplitude 5.0V +/- 5%

» Source impedance < = 50 ohms

» Rise time 1uS⇐

» Duration >= 20uS

The assertion of this signal causes all power regulators to be disabled and the internal power supply rails to be discharged
by crowbar circuits. The shutdown circuitry provides internal energy storage that maintains crowbar activation for at least
2mS following the de-assertion of the shutdown signal. The circuit also incorporates a weak input pulldown resistor so
that the RXT module will operate normally in systems where the rapid shutdown functionality is not used and pin C67 of
the COM Express is left unconnected.

2) Simultaneously with the leading edge of shutdown, the 12V (main) input power to the RXT module is removed and
these input power pins are externally clamped to ground though a crowbar circuit located on the COM Express carrier
board. This external clamping circuit must maintain a maximum resistance of approximately 1 ohm and be activated for a
minimum of 2mS.

3) Simultaneously with the leading edge of shutdown, the 5V (standby) input power to the RXT module is removed, if
present. External clamping on these pins is not necessary.

Crowbar implementation details

As a tool for designing the internal crowbars, Kontron developed tallied the total capacitance present on each of the
internal power rails, and calculates the required discharge resistance in order to achieve the desired voltage decay time
constant. The principal design criteria are that each supply rail must decay to 37% of initial value (equivalent to 1RC)
within 250uS, and to below 1.5V within 2mS. Analysis shows that the power rails fall into four general classes. Each class
of power rails has a corresponding discharge strategy.

1) Power Input Rails: The main 12V power input rail incorporates about 300uF of distributed capacitance. This rail must be
discharged by an external crowbar located on the carrier board, which must provide a shunt resistance of approximately 1
ohm. The peak power dissipation in this crowbar resistance will be relatively high (on the order of 150W when the crowbar
is activated), but will diminish very rapidly as the input capacitors discharge.

2) Low Voltage, High Power Rails: Each of these 5 “major” internal supply rails has an output voltage in the 1.0 V to 1.5V
range, and each rail has between 1500uF and 3300uF of output capacitance. The required discharge resistances for these
rails are in the range of 0.1 to 0.2 ohm, and peak discharge currents are in the range of 8 to 16A.

The discharge circuit for each rail is implemented with a “pulse withstanding” thick-film SMT resistor in series with a low­RDSon MOSFET. The resistor peak powers are in the 8W to 20W range; depending on PCB layout considerations either a
single resistor or multiple smaller resistors may be used to achieve sufficient pulse handling capability.

Because of the relatively high currents in the discharge paths, these crowbar circuits require wide copper traces and
careful component placement adjacent to the output components of the corresponding power supplies.

3) Low Voltage, Low Power Rails: These rails have voltages of 1.8V or less and capacitances under 1000uF, with peak
discharge currents <3A. The discharge circuits for these rails are also implemented with resistor(s) and a low-RDSon

32

COMe-bSC2 / Features and Interfaces

MOSFET. In some cases, the peak pulse power dissipation in the resistor(s) is low enough that specialty “pulse
withstanding” resistors are not required.

4) Medium Voltage Rails: These 3.3V and 5V rails typically have relatively small output capacitances and peak discharge
currents <1A. The discharge circuits for these rails are typically implemented with conventional resistor(s) and a low­RDSon MOSFET.

Shutdown input circuit details

The shutdown input pin to the RXT module is coupled through a series Schottky diode and a small series resistor to the
gates of all crowbar MOSFETs, connected in parallel. All crowbar MOSFETs are N-channel “logic level” parts that have are
specified for operation at Vgs = 4.5V. Three additional components are connected in parallel between the MOSFET gates
and ground:

» A capacitor that provides energy storage to keep the MOSFETs conducting for several mS after the shutdown signal

is de-asserted.

» A high-value resistor that provides a discharge path for the capacitor as well as a pulldown resistance (to insure

that the shutdown circuits remain inactive if the shutdown pin is left floating).

» A 6.2V zener diode that protects the MOSFET gates from damage due to input ESD or input overdrive.

In order to insure that the crowbars do not “fight” active switching regulators while the input capacitors are being
discharged, the shutdown circuit rapidly crowbars the 5V rail, with a time constant <10uS. The 5V rail powers most of the
remaining switching regulators, and as its voltage falls below about 4V those regulators enter under-voltage lockout
mode and cease to operate. Additionally, by using the UVLO mechanism in the design of the RXT module, Kontron
minimizes the risk of inadvertently affecting the standard power sequencing logic for such RXT modules. Two of the
switching regulators do not require the 5V supply for operation, and in those two cases it will be necessary to clamp the
enable inputs to ground when shutdown begins.

4.3 LPC

The Low Pin Count (LPC) Interface signals are connected to the LPC Bus bridge located in the CPU or chipset. The LPC low
speed interface can be used for peripheral circuits such as an external Super I/O Controller, which typically combines
legacy-device support into a single IC. The implementation of this subsystem complies with the COM Express®
Specification. Implementation information is provided in the COM Express® Design Guide maintained by PICMG. Please
refer to the official PICMG documentation for additional information.

The LPC bus does not support DMA (Direct Memory Access) and a clock buffer is required when more than one device is
used on LPC. This leads to limitations for ISA bus and SIO (standard I/O´s like Floppy or LPT interfaces) implementations.

All Kontron COM Express® Computer-on-Modules imply BIOS support for following external baseboard LPC Super I/O
controller features for the Winbond/Nuvoton 5V 83627HF/G and 3.3V 83627DHG-P:

83627HF/G Phoenix BIOS AMI CORE8 AMI / Phoenix EFI

PS/2 YES YES YES

COM1/COM2 YES YES YES

LPT YES YES YES

Features marked as not supported do not exclude OS support (e.g. HWM can be accessed via SMB). For any other LPC
Super I/O additional BIOS implementations are necessary. Please contact your local sales or support for further details.

4.4 Serial Peripheral Interface (SPI)

The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates
in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame.
Multiple slave devices are allowed with individual slave select (chip select) lines. Sometimes SPI is called a “four wire”
serial bus, contrasting with three, two, and one wire serial buses.

The SPI interface can only be used with a SPI flash device to boot from external BIOS on the
baseboard.

4.5 SPI boot

The COMe-bSC2 supports boot from an external SPI Flash. It can be configured by pin A34 (BIOS_DIS#0) and pin B88
(BIOS_DIS1#) in following configuration:

BIOS_DIS0# BIOS_DIS1# Function

open open Boot on-module BIOS

GND open Boot baseboard LPC FWH

open GND Baseboard SPI = Boot Device 1, on-module SPI = Boot Device 2

GND GND Baseboard SPI = Boot Device 2, on-module SPI = Boot Device 1

By default only SPI Boot Device 1 is used in configuration 3 & 4. Both SPI Boot Devices are
used by splitting the BIOS with modified descriptor table in customized versions only

Using an external SPI flash

To program an external SPI flash follow these steps:

» Connect a SPI flash with correct size (similar to BIOS ROM file size) to the module SPI interface

» Open pin A34 and B88 to boot from the module BIOS

» Boot the module to DOS/EFI-Shell with access to the BIOS image and Firmware Update Utility provided on EMD

Customer Section

» Connect pin B88 (BIOS_DIS1#) to ground to enable the external SPI flash

» Execute Flash.bat/Flash.efi to program the complete BIOS image to the external SPI flash

» reboot

Your module will now boot from the external SPI flash when BIOS_DIS1# is grounded.

External SPI flash on Modules with Intel® ME

If booting from the external (baseboard mounted) SPI flash then exchanging the COM Express® module for another one
of the same type will cause the Intel® Management Engine to fail during next start. This is by design of the ME because it
bounds itself to the very module it has been flashed to. In the case of an external SPI flash this is the module present at
flash time.

To avoid this issue please make sure to conduct a complete flash of the external SPI flash device after changing the
COMexpress module for another one. If disconnecting and reconnecting the same module again this step is not necessary.

4.9 Dual Staged Watchdog Timer

Basics

A watchdog timer (or computer operating properly (COP) timer) is a computer hardware or software timer that triggers a
system reset or other corrective action if the main program, due to some fault condition, such as a hang, neglects to
regularly service the watchdog (writing a “service pulse” to it, also referred to as “kicking the dog”, “petting the dog”,
“feeding the watchdog” or “triggering the watchdog”). The intention is to bring the system back from the nonresponsive
state into normal operation.

The COMe-bSC2 offers a watchdog which works with two stages that can be programmed independently and used one by
one.

Time-out events

Reset

A reset will restart the module and starts POST and operating system new.

NMI

A non-maskable interrupt (NMI) is a computer processor interrupt that cannot be ignored by st andard interrupt masking techniques in the system. It is
typically used to signal attention for non-recoverable hardware errors.

SCI

A system control interrupt (SCI) is a OS-visible interrupt to be handled by the OS using AML code

Delay

Might be necessary when an operating system must be started and the time for the first trigger pulse must extended. (Only available in the f irst stage)

WDT Signal only

This setting triggers the WDT Pin on baseboard connector (COM Express® Pin B27) only

Cascade:

Does nothing, but enables the 2nd stage af ter the entered time-out.

WDT Signal

B27 on COM Express® Connector offers a signal that can be asserted when a watchdog timer has not been triggered within
time. It can be configured to any of the 2 stages. Deassertion of the signal is automatically done after reset. If
deassertion during runtime is necessary please ask your Kontron technical support for further help.

4.10 Speedstep Technology

The Intel® processors offer the Intel® Enhanced SpeedStep™ technology that automatically switches between maximum
performance mode and battery-optimized mode, depending on the needs of the application being run. It enables you to
adapt high performance computing on your applications. When powered by a battery or running in idle mode, the
processor drops to lower frequencies (by changing the CPU ratios) and voltage, conserving battery life while maintaining
a high level of performance. The frequency is set back automatically to the high frequency, allowing you to customize
performance.

In order to use the Intel® Enhanced SpeedStep™ technology the operating system must support SpeedStep™ technology.

By deactivating the SpeedStep feature in the BIOS, manual control/modification of CPU performance is possible. Setup
the CPU Performance State in the BIOS Setup or use 3rd party software to control CPU Performance States.

4.11 C-States

New generation platforms include power saving features like SuperLFM, EIST (P-States) or C-States in O/S idle mode.

Activated C-States are able to dramatically decrease power consumption in idle mode by reducing the Core Voltage or
switching of parts of the CPU Core, the Core Clocks or the CPU Cache.

Following C-States are defined:

C-State Description Function

C0 Operating CPU fully turned on

C1 Halt State Stops CPU main internal clocks via software

C1E Enhanced Halt Similar to C1, additionally reduces CPU voltage

C2 Stop Grant Stops CPU internal and external clocks via hardware

C2E Extended Stop Grant Similar to C2, additionally reduces CPU voltage

C3 Deep Sleep Stops all CPU internal and external clocks

C3E Extended Stop Grant Similar to C3, additionally reduces CPU voltage

C4 Deeper Sleep Reduces CPU voltage

C4E Enhanced Deeper Sleep Reduces CPU voltage even more and turns of f the memory cache

C6 Deep Power Down Reduces the CPU internal voltage to any value, including 0V

C7 Deep Power Down Similar to C6, additionally LLC (LastLevelCache) is switched of f

C-States are usually enabled by default for low power consumption, but active C-States my influence performance
sensitive applications or real-time systems.

» Active C6-State may influence data transfer on external Serial Ports

» Active C7-State may cause lower CPU and Graphics performance

It's recommended to disable C-States / Enhanced C-States in BIOS Setup if any problems occur.

4.12 Hyper Threading

Hyper Threading (officially termed Hyper Threading Technology or HTT) is an Intel®-proprietary technology used to
improve parallelization of computations performed on PC´s. Hyper-Threading works by duplicating certain sections of the
processor—those that store the architectural state but not duplicating the main execution resources. This allows a Hyper­Threading equipped processor to pretend to be two “logical” processors to the host operating system, allowing the
operating system to schedule two threads or processes simultaneously. Hyper Threading Technology support always relies
on the Operating System.

43

COMe-bSC2 / Features and Interfaces

4.13 VID-x

The processor implements the VID-x feature for improved control of core voltage levels when the processor enters a
reduced power consumption state. VID-x applies only when the processor is in the Intel Dynamic Acceleration Technology
performance state and one or more cores are in low-power state (i.e., CC3/CC4/CC6). VID-x provides the ability for the
processor to request core voltage level reductions greater than one VID tick. The amount of VID tick reduction is fixed and
only occurs while the processor is in Intel Dynamic Acceleration Technology mode. This improved voltage regulator
efficiency during periods of reduced power consumption allows for leakage current reduction which results in platform
power savings and extended battery life.

When in Intel Dynamic Acceleration Technology mode, it is possible for both cores to be active under certain internal
conditions. In such a scenario the processor may draw an Instantaneous current (ICC_CORE_INST) for a short duration of
tINST; however, the average ICC current will be lesser than or equal to ICCDES current specification.

4.14 Intel® Turbo Boost Technology and AVX

For applications that are particularly power-hungry, the new processors provide enhanced Intel® Turbo Boost technology.
This automatically shifts processor cores and processor graphics resources to accelerate performance, tailoring a
workload to give users an immediate performance boost for their applications whenever needed. Another innovation is
the enhancement to the 256-bit instruction set, known as Intel® Advanced Vector Extensions (AVX). AVX delivers
improved performance, rich functionality and the ability to manage, rearrange and sort data in a better way. The new
instruction set accelerates floating-point intensive applications such as “number crunchers” or digital processing of
images, videos and audio data.
Intel® Turbo Boost Technology 2.0

Intel has optimized Intel® Turbo Boost Technology to provide even more performance when needed on the latest­generation Intel® microarchitecture. Intel® Turbo Boost Technology 2.0 automatically allows processor cores to run
faster than the base operating frequency if it's operating below power, current, and temperature specification limits.
Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests the highest processor
performance state (P0).

The maximum frequency of Intel Turbo Boost Technology 2.0 is dependent on the number of active cores. The amount of
time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating
environment. Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:

» Number of active cores

» Estimated current consumption

» Estimated power consumption

» Processor temperature

When the processor is operating below these limits and the user's workload demands additional performance, the
processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost Technology

2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance
and energy efficiency. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is
higher than its rated upper power limit (TDP) for short durations to maximize performance.

COMe-bSC2 / Features and Interfaces

eDP - embedded Display Port

Intel® 6 & 7-Series Chipset based Computer-on-modules support the embedded Display Port shared on Digital Display
Interface DDI3. To enable the eDP, LVDS must be switched off by hardware strap option. This feature is implemented in
COMe-bSC2 (starting with hardware revision CE 2.x.x) and COMe-bIP2/6 by external strap option on the carrier board. The
General Purpose Input GPI3 (COM Express Pin A85) is pulled-up with 10kOhm on the module. Leaving GPI3 open on the
baseboard enables LVDS (default configuration). To enable the eDP instead of LVDS, GPI3 must be pulled-down with a
resistor ≤1kOhm or tied directly to GND during boot-up.

The GPIO should not be used during boot-up until CB_RESET# becomes inactive

Digital Display Interface Features

The integrated Intel® GMA HD/HD3000 (Gen6) graphics supports:

» High-bandwidth Digital Content Protection (HDCP) on HDMI and DisplayPort with up to 2 HDCP streams

simultaneously

» One active Protected Audio and Video Path (PAVP) session on HDMI or DisplayPort

» Dual Stream DP/HDMI Audio if activated in BIOS (See BIOS Chapter HDAudio Configuration) and O/S (HDMI codec

DDI enabled)

» DP/HDMI/DVI Hot-plug (low-active)

COMe-bSC2 / Features and Interfaces

DDI Design Consideration

» For sufficient signal quality baseboard designs with long signal lanes or impedance leaps may require an Equalicer

or Redriver for the digital display interfaces

» Due to backwards compatibility to former platforms the DDI hot-plug detection is converted to low active

» SDVO can be used for external conversion to VGA, LVDS, TV-out and requires additional hardware on your baseboard

» DisplayPort can be used directly or with external adapters for HDMI, DVI or VGA

» HDMI or DVI usage on a baseboard requires a level shifter

Find more details for DDI usage as DisplayPort, HDMI or DVI with schematic examples
available on http://emdcustomersection.kontron.com

DVI-I Design Topology

DVI-I is supported on PCH Digital Display Port B (COM DDI1) only. The implementation involves routing VGA and DVI-D
signals to DVI-I connector:

» VGA port RGB signals should be routed to Analog RGB pins on the DVI-I connector

» DVI Data and Clock signals on PCH Digital Display Port B should be routed to TMDS Data 0, 1 and 2 pins and TMDS

Clock pin of DVI-I connector respectively

» DVI HPD signals should be routed to the HPD pin of the DVI-I connector

» DVI DDC Clock and Data signals on PCH Digital Display Port B should be routed to the DDC Clock and Data pins of the

DVI-I connector.

4.17 Hybrid Graphics / Multi-monitor

The COMe-bSC2 supports Hybrid Multi-monitor function which is one form of Intel's Hybrid Graphics where integrated
graphics (in Chipset or CPU) is available to operate simultaneously with external PEG; PCIe or PCI graphics. This feature
enables concurrent function of Intel's integrated Graphics Processing Unit (GPU/iGFX) along with a discrete GPU solution,
allowing for operability of greater than two independently-driven displays. The O/S will handle control of the multiple
GPU display adapters appropriately. For example, WindowsXP supports The Microsoft Windows XP Display Driver Model
(XPDM) which allows loading and support of multiple graphics drivers. Windows 7 continues that legacy XPDM support but
also adds WDDM v1.1 which, like XPDM, allows for simultaneous multiple graphics drivers (Windows Vista WDDM v1.0 did
not allow this capability). Operating system applications will be adapter-unaware through use of the O/S GUI APIs and will
utilize the adapter associated with the primary display, regardless of which display the image is located on.

Some applications may be adapter-aware, e.g., full-screen applications and system
applications like the compositor. A number of software tools designed to assist multi­monitor use are available from third parties. One example is the UltraMon* utility for multi­monitor systems, which helps with the position of applications, assists desktop wallpapers
and screen savers in multi-monitor configurations.

Hybrid Multi-monitor mode is recommended to be accomplished using a discrete third-party PCI Express graphics card
either into the PEG slot of the platform or into an available PCI Express slot routed off of the I/O subsection of the chipset.

Requirements

» Baseboard supporting PEG (alternatively PCIe or PCI)

» Module BIOS which allows switching between iGFX and discrete GPU (iGFX must be set to primary boot display)

» O/S supporting heterogeneous display adapters (Linux / WindowsXP / Windows 7)

Setup a Multi-monitor system

» Start without the discrete GPU seated in the system

» Select IGD as Primary Boot Display in BIOS Setup

» Boot into O/S and install drivers requested for the integrated GPU

» Shut down the system and insert the discrete GPU

» Boot into O/S and install drivers requested for the discrete GPU (if necessary in Safe mode)

» Set the Windows Display properties as referenced below (example: WindowsXP)

In most cases the graphical user interfaces (e.g. ATI Catalyst Control Center) for both GPUs
may not run properly. It's recommended to use O/S implemented Display Properties like in
screenshot above

4.18 Intel® vPro™ technology

Kontron and Intel® are addressing the security and manageability challenges facing embedded systems today with the
implementation of Intel® vPro™ technology to enable: » System integrity » Secure isolation » Remote systems
management

First, system integrity is the ability to identify whether the system hardware or system software has been modified
without authorization. When a system’s integrity is known, the system can be thought of as a trusted system. Second,
secure isolation is the ability to use platform hardware to separate processes, resources, and data on the system such that
they cannot interact with each other in unintended ways. By providing hardware-assisted isolation, there is limitless
security, privacy, and cost savings that can be realized through consolidation and workload isolation. Finally, remote
systems management is the ability to troubleshoot, perform power management or system verification through secure
channels. Significant cost savings and efficiencies can be realized through remote management allowing for increased
system up time and the ability to manage or diagnose a system, even when powered down.

Intel® vPro™ technology itself is special functionality designed into both, the processor and the chipset. The three
technologies that comprise Intel® vPro™ technology are: Intel Virtualization Technology (Intel® VT), Intel Trusted
Execution Technology (Intel® TXT) and Intel Active Management Technology (Intel® AMT).

Intel® VT provides hardware-based assists making secure isolation more efficient and decreases the virtualization
footprint, lowering the effective attack surface of a solution. This hardware-based technology can help to protect
applications and information by running multiple operating systems (OSs) in isolation on the same physical system. A
virtual guest OS can be created in an entirely separate space on the physical system to run specialized or critical
applications. Virtual environments leverage Intel® VT for memory, CPU, and Directed I/O virtualization. Intel® TXT
provides the ability to use hardware-based mechanisms to verify system integrity during the boot process. It also provides
system memory scrubbing that protects against soft reset attacks. Virtualized environments take advantage of Intel® TXT
launch environment verification to establish a dynamic root of trust providing added security to hypervisor or virtual
machine monitor (VMM).

Mechanisms employed by Intel® AMT include domain authentication, session keys, persistent data storage in the Intel®
AMT hardware, and access control lists. Only firmware images that are digitally signed by Intel are permitted to load and
execute. This set of hardware-based features is targeted for businesses and allows remote access to the system, whether
wired or wireless, for management and security tasks. Because of the special hardware capabilities provided by Intel®
AMT, out of band access is available even when the OS is not functional or system power is off.

Intel® TXT and Intel® AMT are disabled by default. Please contact your local sales or
support for BIOS versions with full vPro™ support

8 BIOS Operation

The module is equipped with AMI® Aptio, which is located in an onboard SPI serial flash memory.

8.1 Determining the BIOS Version

The AMI® Aptio version is displayed in the main menu of the setup utility.

» BIOS Vendor: American Megatrends

» Core Version: x.x.x.x

» BIOS Date: mm/dd/yyyy hh:mm:ss

» BIOS Version: CHR2 / CXR2 (HudsonBay)RXXX

8.2 BIOS Update

Kontron provides continuous BIOS updates for Computer-on-Modules. The updates are provided for download on

http://emdcustomersection.kontron.com with a detailed change description within the according Product Change

Notification (PCN). Please register for EMD Customer Section to get access to BIOS downloads and PCN service.

Modules with BIOS Region/Setup only inside the flash can be updated with AFU utilities (usually 1-3MB BIOS binary file
size) directly. Modules with Intel® Management Engine, Ethernet, Flash Descriptor and other options additionally to the
BIOS Region (usually 4-8MB BIOS binary file size) requires a different update process with Intel Flash Utility FPT and a
wrapper to backup and restore configurations and the MAC address. Therefore it is strongly recommended to use the batch
file inside the BIOS download package available on EMD Customer Section.

» Boot the module to DOS/EFI Shell with access to the BIOS image and Firmware Update Utility provided on EMD

Customer Section

» Execute Flash.bat in DOS or Flash.nsh in EFI Shell

Any modification of the update process may damage your module!

70

COMe-bSC2 / BIOS Operation

Backup the BIOS / Create a BIOS with custom defaults:

» Change your BIOS settings according your needs

» Save and Exit Setup with option “Save as User Defaults”. Your customized settings are now stored inside the flash in

a second area additional to the manufacturer defaults

» Boot the module to DOS or EFI Shell with access to the update utilities

» Extract the BIOS region including your custom defaults with afuefix64.efi CBIOS.bin /O in EFI Shell or afudos.exe

CBIOS.rom /O in DOS

Now you can clone the BIOS with your customized default settings to other modules or external SPI flashes with above
mention AFU utilites. On modules with Management Engine and Ethernet inside the Flash the same BIOS core version
should already be programmed on the target.

AMI APTIO update utilities for DOS, EFI Shell and Windows are available for free at AMI.com:

is enabled. Range 2 - 32

89

COMe-bSC2 / BIOS Operation

Passive Cooling

The ACPI OS assesses the optimum CPU performance change necessary to lower the temperature using the following
equation

ΔP[%] = TC1(Tn-Tn-1) + TC2(Tn-Tt)

ΔP is the performance delta, Tt is the target temperature = passive cooling trip point. The two coefficients TC1 and TC2
and the sampling period TSP are hardware dependent constants the end user must supply. It’s up to the end user to set
the cooling preference of the system by setting the appropriate trip points in the BIOS setup.

Flow Control

None
Hardware RTS/CTS

Flow control can prevent data loss from buffer overflow.
When sending data, if the receiving buffers are full, a
