2 Introduction
2.1 ETX®-CN8
ETX®-CN8 is the latest 'Computer On Module' based on ETX® 3.0 standard. The new ETX®-CN8 module is
based on the VIA C7® processor and VIA Eden® processor as well as the VIA CN896 and VIA VT8237S
chipset.
ETX®-CN8 modules also will provide the following interfaces that are always located in the same physical
position on each board, thus guaranteeing scalability between modules.
It also takes advantage of the new ETX® 3.0 specification that allow for 2 Serial ATA ports without
violating the existing ETX® 2.8 pin usage.
For further expansions two IDE ports with Ultra133 DMA capabilities are available. The ISA bus signals
are also available. A lot of existing ISA boards can still be used via an ISA slot on a baseboard. This
avoids expensive redesigns and well proven ISA cards to PCI versions for standard PC motherboards.
PCI32, USB 2.0, Serial ATA, Parallel ATA, LVDS Multi-Media ports as well as an ACPI (Advanced
Configuration and Power Interface) for optimized power management. The JILI display interface
technology ensures automatic setting of the video controller parameters for the attached LCD panel.
Seven mounting holes on the board provide secure mounting to allow the module increased shock and
vibration resistance.
2.2 ETX® Documentation
This product manual serves as one of three principal references for an ETX® design. It documents the
specifications and features of ETX®-CN8. The other two references, which are available from the Kontron
Embedded Modules GmbH Web site, include:
®
The ETX® Component SBC™ Specification defines the ETX® module form factor,
pinout, and signals. You should read this first.
®
The ETX® Component SBC™ Design Guide serves as a general guide for baseboard
design, with a focus on maximum flexibility to accommodate a range of ETX®
modules.
Note: Some of the information contained within this product manual applies only to certain product revisions
(Prev: xxx). If certain information applies to specific product revisions (Prev: xxx) it will be stated. Please
check the product revision of your module to see if this information is applicable.

Kontron User's Guide ETX®-CN8 9
2.3 ETX® Benefits
Embedded technology extended (ETX®) modules are very compact (~100mm square, 12mm thick),
highly integrated computers. All ETX® modules feature a standardized form factor and a standardized
connector layout that carry a specified set of signals. This standardization allows designers to create a
single-system baseboard that can accept present and future ETX® modules.
ETX® modules include common personal computer (PC) peripheral functions such as:
®
Graphics
®
Parallel, Serial, and USB ports
®
Keyboard/mouse
®
Ethernet
®
Sound
®
IDE
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.
Peripheral PCI or ISA buses can be implemented directly on the baseboard rather than on mechanically
unwieldy expansion cards. The ability to build a system on a single baseboard using the computer as one
plug-in component simplifies packaging, eliminates cabling, and significantly reduces system-level cost.
A single baseboard design can use a range of ETX® modules. This flexibility can differentiate products at
various price/performance points, or to design future proof systems that have a built-in upgrade path.
The modularity of an ETX® solution also ensures against obsolescence as computer technology evolves.
A properly designed ETX® baseboard can work with several successive generations of ETX® modules.
An ETX® baseboard design has many advantages of a custom, computer-board design but delivers better
obsolescence protection, greatly reduced engineering effort, and faster time to market.

3.5 MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of
manufacturer’s test data, if the data was available, and a Bellcore calculation for the remaining parts.
The Bellcore calculation used is “Method 1 Case 1”. In that particular method the 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. Manufacturer’s data has been used wherever possible. The
manufacturer’s data, when used, is specified at 50° C, so in that sense the following results are slightly
conservative. The MTBF values shown below are for a 40° C in an office or telecommunications
environment. Higher temperatures and other environmental stresses (extreme altitude, vibration, salt
water exposure, etc.) lower MTBF values.
®
System MTBF (hours) : 174189
Notes: Fans usually shipped with Kontron Embedded Modules 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 for
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.

PCI Bus
The implementation of this subsystem complies with the ETX® Specification. Implementation
information is provided in the ETX® Design Guide. Refer to the documentation for additional
information.
USB
The Universal Serial Bus controller is USB v2.0 / 1.1 and Universal HCI v2.0 / 1.1 compliant. The VT8237S
includes four root hubs with eight function ports with integrated physical layer transceivers. The USB
controller allows hot plug and play and isochronous peripherals to be inserted into the system with
universal driver support. The controller also implements legacy keyboard and mouse support so legacy
software can run transparently in a non-USB-aware OS environment
Configuration
The USB controllers are PCI bus devices. The BIOS allocates required system resources during
configuration of the PCI bus.
Note: Only 2 root hubs with 4 ports are wired with the ETX® connector according to the ETX® standard
Audio
The ETX®-CN8 PCI audio controller is integrated in the VIA® VT8237S southbridge. The audio codec is
compatible with AC97.
Configuration
The audio controller is a PCI bus device. The BIOS allocates required system resources during
configuration of the PCI device.
Serial IRQ
The serial IRQ pin offers a standardized interface to link interrupt request lines to a single wire.
Configuration
The serial IRQ machine is in “Quiet Mode”, the frame size is 21 frames and the start frame pulse width is
4 clocks.
3.3V Power Supply for External Components
The ETX®-CN8 offers the ability to connect external 3.3V devices to the onboard-generated supply
voltage. Pin 12 and Pin 16 of Connector X1 are used to connect to the +3.3V ±5% power supply. The
maximum external load is 500mA. Contact Kontron Embedded Systems Technical Support for help with
this feature.
Warning: Do not connect 3.3 V pins to external 3.3 V supply.

Parallel Port / Floppy Interfaces
You can configure ETX® parallel port interfaces as conventional PC parallel ports or as an interface for a
floppy-disk drive. You can select the operating mode in the BIOS settings or by a hardware mode-select
pin.
If Pin X3-51 (LPT/FLPY#) is grounded at boot time, the floppy support mode is selected. If the pin is left
floating or is held high, parallel-port mode is selected. The mode selection is determined at boot time. It
cannot be changed until the next boot cycle.

5 Special Features
Kontron User's Guide ETX®-CN8 37
5 Special Features
5.1 Watchdog Timer
The watchdog timer is implemented withing the Winbond W83627HG. The WDT can also be controlled by
the JIDA BIOS support (Refer to
HUAppendix F: JIDA StandardUH). The application software should strobe the
WDT to prevent its timeout. Upon timeout, the WDT resets and restarts the system. This provides a way to
recover from program crashes or lockups.
Configuration
You can program the timeout period for the watchdog timer in two ranges:
®
1-second increments from 1 to 255 seconds
®
1-minute increments from 1 to 255 minutes
The watchdog can release a NMI or a reset.
Contact Kontron Embedded Modules technical support for information on programming and operating
the WDT.
5.2 SATA Support
The ETX®-CN8 supports two SATA ports compliant to the ETX® 3.0 specification

6 Design Considerations
Kontron User's Guide ETX®-CN8 38
6 Design Considerations
6.1 Thermal Management
A heat-spreader plate assembly is available from Kontron Embedded Modules GmbH for the ETX®-CN8.
The heat-spreader plate on top of this assembly is NOT a heat sink. It works as an ETX®-standard thermal
interface to use with a heat sink or other cooling device.
External cooling must be provided to maintain the heat-spreader plate at proper operating
temperatures. Under worst-case conditions, the cooling mechanism must maintain an ambient air and
heat-spreader plate temperature of 60° C or less.
The aluminum slugs and thermal pads on the underside of the heat-spreader assembly implement
thermal interfaces between the heat spreader plate and the major heat-generating components on the
ETX®-CN8. About 80 percent of the power dissipated within the module is conducted to the heatspreader plate and can be removed by the cooling solution.
For 1000MHz and 1500MHz modules, the heat dissipated into the plate ranges from 18 to 20 watts.
Design a cooling solution to dissipate the heat load on a heat-spreader plate at a minimum of 20 watts
to accommodate all ETX®-CN8 modules.
You can use many thermal-management solutions with the heat-spreader plates, including active and
passive approaches. The optimum cooling solution varies, depending on the ETX® application and
environmental conditions. Please see the ETX® Design Guide for further information on thermal
management.

6.3 ETX-CN8® onboard fan connector
This section describes how to connect a fan to the connector located directly on the ETX®-CN8. With
certain BIOS-settings it is possible to control the fan depending on the Active Trip Point temperature.
The fan switches on/off depending on the adjusted Active Trip Point temperature. In order for this
feature to function properly an ACPI compliant OS is necessary.
Note: The ETX® CN8 BIOS supports only turning the onboard FAN ON/OFF. For additional support 3rd party software
is necessary.

7 Important Technology Information
The following technological information is designed to give the reader a better understanding of some of
features of the ETX®-CN8. This information can be referenced when reading the
HUSystem ResourcesUH and
HUBIOS OperationUH sections that follow. There are also references to additional documentation that will
help to develop a better understanding of the technical information described herein.
7.1 I/O APIC vs 8259 PIC Interrupt mode
The I/O APIC (Advanced Programmable Interrupt Controller) handles interrupts differently then the
8259 PIC. The following information explains these differences.
7.1.1 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.
7.1.2 Interrupt priority
The priority of interrupts in the I/O APIC is independent of the interrupt number.
7.1.3 More interrupts
The I/O APIC in the chipset of the ETX®-CN8 supports a total of 24 interrupts.
The APIC is not supported by all operating systems. The APIC mode must be enabled in the BIOS setup
before the OS installation. APIC only works in ACPI mode.
Note: Enable the APIC mode if your OS supports it.
7.2 Thermal Monitor and Catastrophic Thermal Protection
The Thermal Monitor within the VIA® processor helps to control the processor temperature.
7.3 ACPI Suspend Modes and Resume Events
The ETX®-CN8, supports the S1 (POS=Power On Suspend) state and S3 state (=Save to Ram). S4 (=Save
to Disk) is not supported by the BIOS (S4_BIOS) but it is supported by the following operating systems:
®

9.4 Updating and Restoring of BIOS
AMI’s AFUDOS utility allows you to update or restore the BIOS with a newer version or restore a corrupt
BIOS by using a floppy disk without having to install a new ROM chip.
BIOS Update
Download the compressed BIOS File from
HUKontron EMD CustomerSectionUH and unzip all files on a DOS
bootable media like Floppy Disk or USB stick. Execute the batch file flash.bat to update the BIOS.
File Purpose
BIOS.ROM Actual BIOS image to be programmed into Flash ROM
AFUDOS.EXE Phoenix DOS tool to program the Flash ROM.
Flash.bat Batch File with necessary flash command. Execute this file to update the BIOS.
9.5 Preventing Problems When Updating or Restoring BIOS
Updating the BIOS represents a potential hazard. Power failures or fluctuations that may occur during
updating the Flash ROM can damage the BIOS code, making the system unbootable.
To prevent this potential hazard, many systems come with a boot-block Flash ROM. The boot-block
region contains a fail-safe recovery routine. If the boot-block code finds a corrupted BIOS (checksum
fails), it boots into the crisis recovery mode and loads a BIOS image from a crisis diskette (see above).
Additionally, the end user can insert an update key into the serial port (COM1 only) to force initiating
the recovery routine for the boot block.

10 Appendix F: JIDA Standard
Kontron User's Guide ETX®-CN8 74
10 Appendix F: JIDA Standard
Every board with an on-board BIOS extension supports the following function calls, which supply
information about the board. Jumptec Intelligent Device Architecture (JIDA) functions are called via
Interrupt 15h. Functions include:
®
AH=Eah
®
AL=function number
®
DX=4648h (security word)
®
CL=board number (starting with 1)
The interrupt returns a CL≠0 if a board with the number specified in CL does not exist. CL will equal 0 if
the board number exists. In this case, the content of DX determines if the operation was successful.
DX=6B6Fh indicates success; other values indicate an error.
10.1 JIDA Information
To obtain information about boards that follow the JIDA standard, use the following procedure.
®
Call Get BIOS ID with CL=1.
The name of the first device installed will be returned.
If you see the result Board exists (CL=0), increment CL, and call Get BIOS ID again.
®
Repeat until you see Board not present (CL≠0).
You now know the names of all boards within your system that follow the JIDA
standard.
®
You can find out more information about a specific board by calling the appropriate
inquiry function with the board’s number in CL.
Note: Association between board and board number may change because of configuration changes. Do not rely on
any association between board and board number. Always use the procedure described above to determine
the association between board and board number.
Refer to the JIDA manual in the jidai1xx.zip folder, which is available from the Kontron Embedded
Modules GmbH Web site, for further information on implementing and using JIDA calls with C sample
code.
