Introduction 2.1 JRex-PM The JRex-PM hosts an Intel® Pentium® M processor in combination with an Intel® 855GM/GME 855GM/GME chipset with an integrated graphic memory controller hub. Celeron M versions of this board are possible, too. A DDR-SDRAM-DIMM socket for up to 1 GB allows you to use standard DDR DIMM memory modules. Two USB 2.0 ports and one 10/100 MBit Ethernet interface extend the standard connectivity of one serial, one parallel and a PS/2 mouse/keyboard interface. The JRex-PM is designed in a 3.5" JRex embedded line format, which can be extended with help of the JFLEXTMextension module concept and provides a space-saving, cost-optimized single board computer solution. JFLEX is an extension interface to support additional functions to JRex products. JRex-PM online: 2.2 JRex Embedded Line Family Each JRex is a member of the 3.5" SBC family of Kontron Embedded Modules GmbH. JRex embedded line modules are characterized by the same surface pin-outs and interfaces for Reset/ATX feature, 2xUSB, FAST LAN, PS/2 Keyboard/Mouse connector, Compact-Flash socket, VGA and one serial port. These embedded line family features allow the use of the same chassis over the whole product line and maximize design reuse. JRex embedded line modules allow the use of standard desktop memories and full ATX power supplies. An optional 5V-only version is available, too. These homogeneous features facilitate easy upgrades within the JRex embedded line product family. Connection of displays is simplified when using the onboard standard JILI-Interface (JUMPtec® Intelligent LVDS Interface). JILI automatically recognizes which display is connected and independently sets all video parameters. All JRexes in the embedded line are plug-and-work enabled to further reduce time-to-market. As part of the standard features package, all JRex embedded line modules come with a JUMPtec Intelligent Device Architecture (JIDA) interface, which is integrated into the BIOS of the SBC modules. This interface enables hardware independent access to the JRex features that cannot be accessed via standard APIs. Functions such as watchdog timer, brightness and contrast of LCD backlight and user bytes in the EEPROM can be configured with ease by taking advantage of this standard JRex module feature. The JRex embedded line products support the patented JFLEXTMextension module concept. A variety of JFLEXTMmodules are available to extend the standard functionality of your JRex CPU board. The JFLEX extension bus is an open standard and the specification can be downloaded from the Kontron Web sites. This enables JRex users to develop own JFLEXTMextension boards to fulfill special requirements for their end-user-markets. Introduction 4 4 JRex-PM User's Guide 3. Getting Started Getting started with the JRex-PM is very easy. For location of the connectors, see Appendix E: Connector Layout. Take the following steps: 1. Turn off the power supply. 2.

Safety instructions are given only in English, German, French, Danish, Finish and Spanish. If the battery is accessible by the end user, it is in the responsibility of the customer to give the corresponding safety instructions in the required language(s). Specifications 11 11 JRex-PM User's Guide 4.4 MTBF The following Mean Time Between Failure (MTBF) values were calculated using a combination of manufacturer's test data and a Bellcore calculation for the remaining parts. The Bellcore calculation used is "Method 1 Case 1." In that particular method, components are assumed to be operating at a 50 % stress level in a 40° C ambient environment, and the system is assumed to have not been burned in. The manufacturer's data, when used, is specified at 50° C, which means that the following results are slightly conservative. The MTBF values shown below are for a 40° C office or telecommunications environment. Higher temperatures and other environmental stresses such as extreme altitude, vibration, or salt-water exposure can lower MTBF values. Notes: System MTBF (hours): 171.636 Fans shipped with Kontron Embedded Modules GmbH products have a typical operating life of 50,000 hours. The system MTBF above assumes no fan, but a passive heat-sink arrangement. Estimated RTC battery life (as opposed to battery failures) is not accounted for in the above figures and needs to be considered separately. Battery life depends on temperature and operating conditions. When the Kontron unit has external power, the only battery drain is from leakage paths. Specifications 12 12 JRex-PM User's Guide 4.5 Environmental Specifications 4.5.1 Temperature The Intel Mobile Pentium is specified for proper operation when junction temperature is -M within the specified range of 0 to 100 C C. The Intel® 855GM/GME 855GM/GME Chipset temperature and the Intel® ICH4 I/O Controller Hub 4 (82801DB 82801DB) case temperature are maximum 110 C. Notes: 4.5.2 Operating: 0 to +70 C (*) (with appropriate airflow) Non-operating: -10 to +85 (non-condensing) C (*) The maximum operating temperature is the maximum measurable temperature on any spot on the module's surface.

System Memory 18 18 JRex-PM User's Guide 7. JFLEXTMExtension Concept The patented JFLEXTMExtension concept is based on two connectors with 120 pins each. These connectors allow the JRex CPU board to have extra functions. The JRex-PM provides: Second COM Port (with TTL level signals) Low Pin Count (LPC) Bus for more I/O devices PCI Bus for up to 3 additional PCI devices AC97 Bus for sound features LVDS panel output Digital video out ports (DVOB and DVOC) for additional TV-Out Encoders, TMDS and LVDS transmitters There are already some JFLEXTMextension modules available from Kontron Embedded Modules GmbH. Kontron also will offer additional functions in the future. Please visit the Kontron Web site for more information about available extension modules or click the following link: "http://emea.kontron.com/index.php?id=82&cat=191". The JFLEXTMextension specification with design guidelines is available from the Kontron web site, too. If you have more ideas for more functionality, please inform Kontron via your sales channel. You also can join our certified partner program, if you are interested and if you have experiences on digital panel adaptations or on PCI Bus designs. Please go to the Kontron Web site to get a membership in the certified partner program. A detailed description of the signals on the JFLEXTM extension connectors and its timing characteristics is beyond the scope of this document. Refer to the specification and design guide available on the Kontron Web site and see the official LPC- and PCI-specifications for further details. The link to the JFLEXTMspecification is: When using a JRex CPU board designed as AT-version (5V-only) the +3.3V for JFLEX extension modules is generated with help of a DC/DC converter. This 3.3V power supply solution does not have the same capabilities as an ATX power supply. In this case the maximum current for all JFLEX extension modules in the system is limited to 300mA. If your JFLEX extension modules need more power, it is strictly recommended to supply via additional power solutions on the JFLEX extension cards. JFLEXTMExtension Concept 19 19 JRex-PM User's Guide 8. Keyboard and Mouse Interface The keyboard and mouse interface is available through the combined PS/2 connector X12 (6 pins). To find the location of the keyboard and mouse connector, please see the "Appendix E: Connector Layout" chapter. A PS/2-Keyboard can be directly connected to this interface.

This connector represents the JILI interface (JUMPtec Intelligent LVDS Interface). The implementation of this subsystem complies with the JILI Specification of Kontron Embedded Modules GmbH. This JRex already supports the JILI3 implementation. A variety of cables for different display types are available from Kontron. Please refer to the cable list on the Kontron Web site for part numbers and cable names. A detailed description of the JILI interface standard also is available in a separate document JILIM?.PDF. The three question marks represent the document's revision number. You can download the document from the Kontron Web site, or contact your local Kontron technical support to receive it. To find the location of this interface, please see the "Appendix E: Connector Layout" chapter. 11.4 Display Power Considerations When using a LCD Panel, additional voltages may be required to drive the display's logic and to supply the backlight converter and the display's contrast voltage. The display logic may require +5V for standard or +3.3V for low-power LCDs. Contrast voltages for passive displays are normally very different and can range from ­30V to +30V. Backlight converters usually are +5V or +12V types. When using a Kontron JILI cable, you do not need to determine such configurations. Display logic voltage and contrast voltage come pre-configured on the JILI cable. On occasion, backlight voltage has to be adjusted on the cable. Even though the JRex-PM is also available as a +5V-only board, you need to supply the +12V for the backlight converter additionally when using such a converter type. The onboard 3.3V-circuitry of the JRex-PM and the +3.3V logic voltage of low-voltage panels are powered by separate voltage regulators. The one for the LCD is mounted on the JILI adapter cable. Graphic Interfaces 27 27 JRex-PM User's Guide 11.5 Connecting a LCD Panel To determine whether your panel display is supported, check the Kontron Web site for panel lists. We regularly update the list of panels that have been tested with our boards. Many panel adapters for a wide spread variety of displays are available through Kontron. If you use one of those adapters supplied by Kontron, configuration is easy: 1. Check whether you have the correct adapter and cable for the panel you plan to use. Inspect the cable for damages. 2. Disconnect the power from your system. 3. Connect the panel adapter to the LCD Panel connector (JILI) on the JRex-PM. 4. Connect the other end of the cable to your display. 5. Connect the backlight converter. 6. Supply power to your system. 7. If no image appears on your display, connect a CRT monitor to the CRT connector. 8. If necessary program the EEPROM on the JILI cable with the matching configuration data. 9. If you still do not see improvement, consider contacting the dealer for technical support. 11.6 Configuration You can set the general configuration for the graphic controller in the BIOS setup utility. Refer to the "Advanced Chipset Control Submenu" and the "Display Control Submenu" in the "Appendix B: BIOS Operation" chapter for more configuration information. You can download drivers for the graphics controller from the Kontron Web site. For further information, read the read-me or help files or contact technical support. 11.7 Graphics Technical Support If problems occur, you can solve some of them by using the latest drivers for the graphics controller. Kontron provides you with the latest tested drivers, which can differ from newer ones.

The fan will automatically turn on whenever this trip point temperature value is reached. Setting this item to disabled means the fan will always run, except when the operating system takes control over it. Fan Interface 38 38 JRex-PM User's Guide 17. Power Interface The JRex-PM is available with two different power interface connectors. It can be either equipped with an ATX power connector or with an AT power connector (+5V-only) version. The ATX-version has a standard 20-pin ATX-connector, while the AT-version uses a 4-pin power connector. 17.1 Power Interface Connectors 17.1.1 ATX Connector Version This power connector is available through the X14 connector (20 pins). To find the location of this interface, please see the "Appendix E: Connector Layout" chapter. The JRex-PM requires +5V, +5V Standby and +3.3V to be supplied to the board. Additionally some LCD panel backlight inverters may need +12V, as well as some JFLEXTMextension modules or some hard disk and floppy disk drives. The +12V is not generated onboard of the JRex-PM and needs to be supplied, too, as soon as peripheral devices require this voltage. Kontron recommends that you use an ATX power supply with this type of JRex-PM, even though not all voltages are required. If you intend to use an AT power supply with this connector, please connect +3.3 V on all pins "V3.3S" and +5V on all pins "V5S" and "V5SB". Leave "ATXPWRGD" and "PSON" unconnected. The following table shows the pin-out of the connector.

The current on these pins is limited to 6A/pin. These pins are ­12V and ­5V on the ATX power supply. On this board they are not required. 39 39 JRex-PM User's Guide 17.1.2 AT Connector Version This power interface is an option to the ATX power interface and uses the connector X17 (4 pins). To find the location of this interface, please see the "Appendix E: Connector Layout" chapter. In this case the JRex-PM requires +5V-only to be supplied to the board. The +3.3V for onboard and external low-power devices is generated onboard by a DC/DC converter. However, the +12V that may be required for the LCD panel backlight inverter, the JFLEXTMextension modules, and some hard disk or floppy disk drives, is not generated onboard and needs to be additionally supplied. The following table shows the pin-out of the connector.

When set to "power off" the power button offers an On/Off function and when set to "Sleep," it offers a Sleep/Wake function. Please refer to the "Power Menu" section in the "Appendix B: BIOS Operation" chapter for more information about power savings. Power Interface 41 41 JRex-PM User's Guide 18. Watchdog Timer The watchdog timer is integrated in the onboard Winbond W83627HF W83627HF controller of the JRex-PM and can issue a reset to the system or generate a non-maskable interrupt (NMI). The watchdog timer circuit has to be triggered within a specified time by the application software. If the watchdog is not triggered because proper software execution fails or a hardware malfunction occurs, it will reset the system or generate the NMI. 18.1 Configuration You can set the watchdog timer to disabled, reset or NMI mode. You can specify the delay time and the timeout (trigger period) from 1 second to 30 minutes. The delay time is the time after first initialization before the trigger period starts. The timeout is the time the watchdog has to be triggered within. You can make the initialization settings in the BIOS setup. Refer to the "Watchdog Settings Submenu" in the "Appendix B: BIOS Operation" chapter for information on configuration. 18.2 Programming 18.2.1 Initialization You can initialize the watchdog timer from the BIOS setup. You also can set up the initialization from the application software with help of the JIDA (Jumptec Intelligent Device Architecture) programmer's interface. 18.2.2 Trigger The watchdog needs to be triggered out of the application software within a specified timeout period. You can only do this in the application software with help of the JIDA programmer's interface. For information about the JIDA programmer's interface refer to the JIDA BIOS extension section in the Appendix B: BIOS chapter and separate documents available in the JIDA software packages on the Kontron Web site. Watchdog Timer 42 42 JRex-PM User's Guide 19. Hardware Monitor The Winbond W83627HF W83627HF controller monitors several critical hardware parameters of the system, including power-supply voltages, fan speed and CPU temperature, which are very important for a high-end computer system to remain stable and properly. This controller is connected via the system management (SM) bus to the south bridge. The following parameters are monitored: +3.3V from onboard DC/DC CPU core voltage +5V standby voltage Battery voltage CPU temperature with on-die diode CPU fan speed 19.1 Configuration You can use the "Hardware Monitor Submenu" in the BIOS Setup Utility to obtain information on voltages, fan speed and to check the temperature of the CPU die. For more information on this submenu, see the "Appendix B: BIOS Operation" chapter in this manual. To monitor the parameters of this feature from your operating system, Kontron recommends that you use the 32-bit protected mode JUMPtec's Intelligent Device Architecture 32-bit driver (JIDA 32) with the test and demo application for Windows 95/98/ME/NT/2000/XP 95/98/ME/NT/2000/XP, which is available on the Kontron Web site. Hardware Monitor 43 43 JRex-PM User's Guide 20. Important Technology Information The following technological information is designed to give you a better understanding of some of the features offered by the JRex-PM. This information can be referenced when reading the Appendix A: System Resource Allocations and Appendix B: BIOS Operation sections that follow. There also are references to additional documentation that will help you develop a better understanding of the technical information. They are listed in the Appendix F: PC-Architecture Information. 20.1 Max CPU Frequency setting Kontron Embedded Modules currently offers four variants of the JRex-PM. They are the 1800MHz Pentium® M 745 version, the 1000MHz Celeron®-M 373 version, the 1500MHz Celeron®-M 373 version and the 800MHz cacheless processor. These variants use a smart BIOS with the capability of identifying the CPU that the module is equipped with. Another feature of the BIOS is its ability to offer the user the option to set the maximum CPU frequency based on the Intel® SpeedStep® technology. Notes: Celeron® M processors do not support this feature. The Max CPU Frequency setting option is only available since BIOS version BQBAR113 BQBAR113. The Max CPU frequency settings available for the modules are as follows: 1800MHz: 600, 800, 1000, 1200, 1400, 1600, 1800MHz (default since BQBAR114 BQBAR114) Selecting frequencies higher then the default may cause the system to reach "Critical Trip Point" and shutdown if a proper cooling solution is not used. Always ensure that you use a proper cooling when selecting higher frequency settings. Refer to the "Power Menu" section in the "Appendix B: BIOS Operation" chapter of this manual for more information. Important Technology Information 44 44 JRex-PM User's Guide 20.2 Thermal Monitor and Catastrophic Thermal Protection 20.2.1 Thermal Monitor The Thermal Monitor within the Pentium M processor helps to control the processor temperature by activating the TCC (Thermal Control Circuit) when the processor silicon reaches its maximum operating temperature. The temperature at which the Intel Thermal Monitor activates the TCC is not user-configurable and is not software visible. The Thermal Monitor controls the processor temperature by modulating (starting and stopping) the CPU core clocks at a 50% duty cycle (TM1) or by initiating an Enhanced Intel SpeedStep® technology transition (TM2*) when the processor silicon reaches its maximum operating temperature. The mode is selectable in the BIOS Setup Utility. Notes: (*) Maximum operating temperature activating TCC: 100°C TM2 is the recommended mode for the Intel Pentium M processor. TM2 is not supported on boards with Celeron® M processor. Thermal Monitor supports two modes to activate the TCC: Automatic and On-Demand mode. The Intel Thermal Monitor Automatic Mode must be enabled via BIOS for the processor to be operating within specification. Automatic mode does not require any additional hardware, software drivers, or interrupt handling routines. 20.2.2 Catastrophic Thermal Protection The Intel Pentium M processor supports the THERMTRIP# signal for catastrophic thermal protection. In the event of a catastrophic cooling failure, the processor will automatically shut down when the silicon has reached the absolute maximum temperature. At this point the system BUS signal THERMTRIP# will go active. THERMTRIP# activation is independent of processor activity and does not generate any bus cycles. The system will immediately shut down. Absolute maximum temperature activating THERMTRIP#: 125°C For more details, see Chapter 5.1.2 of the Intel Pentium M Processor Datasheet. Important Technology Information 45 45 JRex-PM User's Guide 20.3 Processor Performance Control The Pentium M processor can run in different performance states (multiple frequency/voltage operating points). The CPU performance can be altered while the computer is functioning. This allows the processor to run at different core frequencies and voltages depending on CPU thermal state and OS policy. Microsoft Windows XP includes built-in processor performance control to operate the processor more efficiently when it is not fully utilized. Win2k, WinME and Win9x do not support processor performance control. Special software is required for OSes that are not capable of processor performance control. In Windows, the processor performance control policy is linked to the Power Scheme setting in the control panel power option applet. Notes: Windows always runs at the highest performance state when the "Home/Office" or the "Al ways On" power scheme is selected. For more detailed information about processor performance control, see: - Chapter 8 of the ACPI Specification Revision 2.0c - Windows platform design notes 20.4 Thermal Management ACPI allows the OS to play a role in the thermal management of the system. With the OS in control of the operating environment, cooling decisions can be made based on the application load on the CPU and the thermal heuristics of the system. The ACPI thermal solution on JRex-PM supports three cooling policies and their trip points: Active Trip Point Active cooling devices typically consume power and produce noise but are able to cool a thermal zone without limiting system performance. The active cooling trip point declares the temperature threshold OS uses to start/stop active cooling devices (fan). Passive Cooling Trip Point Passive cooling devices produce no noise, but may not be effective enough to cool the thermal zone. The passive cooling trip point declares the temperature threshold in which the OS will start or stop passive cooling. In this case it throttles the processor. Critical Trip Point The OS performs an orderly, but critical, shutdown of the system when the temperature reaches the critical trip point. Important Technology Information 46 46 JRex-PM User's Guide 20.4.1 Processor Clock Throttling The ACPI OS assesses the optimum CPU performance change necessary to lower the temperature using the following equation: P[%] = TC1(Tn-Tn-1) + TC2(Tn-Tt) is the performance delta, Tt is the target temperature = critical trip point. The two coefficients P TC1 and TC2 and the sampling period TSP are hardware dependent constants that you must supply. (See the setup options in the ACPI Control Submenu section in the BIOS Operation chapter). It is up to you to set the cooling preference of the system by setting the appropriate trip points in the BIOS setup. Notes: For more detailed information see Chapter 12 of the ACPI Specification. Important Technology Information 47 47 JRex-PM User's Guide 20.5 I/O APIC vs 8259 PIC Interrupt mode The I/O APIC (Advanced Programmable Interrupt Controller) handles interrupts differently than the 8259 PIC. Enable the I/O APIC mode in the BIOS Setup Utility, if your operating system supports it. The following information explains these differences to the standard 8259 PIC mode: Method of interrupts transmission The I/O APIC transmits interrupts through the system bus and interrupts are handled without the needs for the processor to run an interrupt acknowledge cycle. Interrupt priority The priority of interrupts in the I/O APIC is independent of the interrupt number. More interrupts The I/O APIC in the chipset of the JRex-PM supports a total of 24 interrupts. Notes: The APIC is not supported by all operating systems. Only Windows XP supports APIC. The APIC mode must be enabled in the BIOS setup before the OS installation. APIC only works in ACPI mode. For more detailed information about APIC, see Chapter 8 of the IA-32 IA-32 Intel Architecture Software Developer's Manual, Volume 3. Important Technology Information 48 48 JRex-PM User's Guide 20.6 Native vs. compatible IDE mode 20.6.1 Compatible IDE Mode The ATA controller emulates a legacy IDE controller, which is a non-standard extension of the ISAbased IDE controller. In compatible mode, the controller requires two ISA IRQs (14 and 15) that cannot be shared with other devices. 20.6.2 Native Mode The ATA controller acts as a true PCI device that does not require dedicated legacy resources and can be configured anywhere in the system. ATA controllers running in native mode use their PCI interrupt for both channels and can share this interrupt pin with other devices in the system, like any other PCI device. By requiring only one shareable interrupt instead of two non-shareable ones, native-mode controllers significantly decrease the likelihood that a user will install a device that cannot work because no interrupts are available. Enable Native IDE Support in the BIOS Setup Utility if your OS supports this mode. Notes: The Native Mode is not supported by all operating systems. The Native mode must be enabled in the BIOS setup before the OS installation. Native Mode only works in ACPI mode. For more information see the Microsoft Windows platform design notes about Native-mode ATA. 20.6.3 Native Mode Configuration Windows XP SP1 and Windows Server 2003 will switch a native-mode-capable ATA controller from compatible to native mode if the BIOS indicates that the controller can be switched, the controller supports native mode and the appropriate registry entry is set. You must add a DWORD VALUE called EnableNativeModeATA under / and set 1 as the value. Important Technology Information 49 49 JRex-PM User's Guide 21.

The first 640KB 640KB of DDRSDRAM are used as main memory. Using DOS, you can address 1MB of memory directly. Memory area above 1MB (high memory, extended memory) is accessed under DOS via special drivers such as HIMEM.SYS and EMM386 EMM386.EXE, which are part of the operating system. Please refer to the operating system documentation or special textbooks for information about HIMEM.SYS and EMM386 EMM386.EXE. Other operating systems (Linux or Windows versions) allow you to address the full memory area directly. Upper Memory Use Available Comment A0000h ­ BFFFFh VGA Memory No Mainly used by graphic adapter cards. If a PCI graphic card is in the system this memory area is mapped to the PCI bus.

If JRC software is used, a 16K block is shadowed for BIOS extension, starting with first free area at D0000h, D4000h, D8000hor DC000h. (BIOS extensions do not use the whole shadow block.). No 52 52 JRex-PM User's Guide 21.3.1 Using Expanded Memory Managers JRex-PM extension BIOSes may be mapped to an upper memory area. (See the previous table.). Some add-on boards also have optional ROMs or use drivers that communicate with their corresponding devices via memory mapped I/O such as dual-ported RAM. These boards have to share the upper memory area with the Expanded Memory Manager's EMS frame. This often causes several problems in the system. Most EMMs scan the upper memory area for extension BIOSes (optional ROMs) and choose a free memory area for their frame if it is not explicitly set. Normally, they are not always capable of detecting special memory-mapped I/O areas. You need to tell the EMM which memory areas are not available for the EMS frames, which is most of the time done by using special exclusion parameters. If the Expanded Memory Manager you use cannot detect extension BIOSes (optional ROMs), make sure you excluded all areas in the upper memory, which are used by extension BIOSes, too. Your instruction in the CONFIG.SYS concerning the Expanded Memory Manager should look like this: (question marks symbolize the location of extension BIOS). MS-DOS Example DEVICE=EMM386 EMM386.EXE X=?-? X=E000-FFFF E000-FFFF Notes: When booting up your system using this configuration under MS-DOS, the exclusion of area F000 to FFFF causes a warning. Microsoft reports that this message will always appear when the F000 segment lies in the shadow RAM. This is a bug of EMM386 EMM386, not of the JRex board. Please read the technical manuals of add-on cards used with the JRex-PM for the memory areas they use. If necessary, exclude their memory locations to avoid a conflict with EMM386 EMM386.
