ETX-P3/C3 User’s Guide User Information

2. INTRODUCTION

2.1 ETX-P3/C3

The ETX-P3/C3 is an Intel® Pentium® III or Celeron™ processor-based ETX module. This module uses low-power (mobile) processors, eliminating the need for active cooling in many applications.

The ETX-P3/C3 includes onboard sound, Ethernet, and high-speed AGP graphics subsystems, and a full complement of standard PC/AT I/Os. The SoundBlaster™ compatible sound chip is supported by most operating systems. The Intel 10/100BaseT Ethernet controller also has extensive operating system support. The ATI Rage Mobility AGP video controller operates cathode ray tube (CRT) monitors as well as Low Voltage Differential Signaling (LVDS) liquid crystal display (LCD) panels.

Kontron

Additional onboard communication interfaces include two serial transistor-transistor logic (TTL ports), an enhanced parallel port (EPP) and enhanced capability port (ECP), and two universal serial bus (USB) ports. Access to all I/O signals is through the ETX board-to-board interface connectors. The ETX interface also includes full Industry Standard Architecture (ISA) and Peripheral Component Interconnect (PCI) buses.

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-P3 and ETX-C3 modules. The other two references, which are available from the Kontron Embedded Modules 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.

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.

Introduction ETX-P3/C3 User’s Guide

Kontron

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.

CMOS battery power consumption was measured with an ETX module on a standard Kontron ETX evaluation board. The system was turned off and the battery was removed from the evaluation board. The 2.5 V or 3.0 V of power was supplied from a DC power supply. Do not rely only on the above measured values to calculate the CMOS battery lifetime. We recommend that you measure the current using a complete application in a worst case scenario setting (high temperature / high battery voltage). When calculating CMOS battery lifetime you must also consider the self-discharge of the battery. For detailed information see the Winbond W83977EF-AW datasheet.

3.3.5. APM1.2 Support

Power management implementations of the ETX-P3 and ETX-C3 are identical.

In standby mode, the internal CPU clock is stopped while the external CPU clock is still present.

In suspend mode, the PCI clock and the external CPU clock are stopped. A clock synthesizer, which is affected by power management, controls both clocks.

Also, the north bridge receives notification when the system goes into suspend mode. Consequently, the north bridge then closes internal functions.

10.1 Watchdog Timer

This feature is implemented in the Winbond W83977EF super I/O device. The watchdog timer (WDT) can be configured in BIOS Setup to start after a set amount of time after power-on boot. Once started, the application software strobes the WDT to prevent its timeout. Upon timeout, the watchdog timer will reset and restart the system. This provides a means to recover from program crashes or lockups.

10.1.1. Configuration

The timeout period for the watchdog timer can be programmed in two ranges:

! 1 second increments from 1 to 255 seconds

Kontron

! 1 minute increments from 1 to 255 minutes

11. DESIGN CONSIDERATIONS

11.1 Thermal Management

A heat-spreader assembly is available from Kontron Embedded Modules for the ETX-P3/C3. The heat-spreader plate on top of this assembly is NOT a heat sink. It is intended as an ETXstandard thermal interface to be used 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 heatgenerating components on the ETX-P3/C3. About 80% of the power dissipated within the module is conducted to the heat spreader plate and can be removed from it by the cooling solution.

For the 400 and 500MHz modules, the heat dissipated into the spreader plate is in the 10 to 12 watt range. It is recommended that the cooling solution be designed for a heat spreader plate heat load of 20 watts to accommodate future ETX-P3/C3 modules with faster processors.

For 700MHz modules, the heat dissipated into the plate ranges from 16 to 18 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-P3/C3 modules.

Many thermal-management solutions can be used with the heat-spreader plate, 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 thermal-management information.

14.10 Updating or Restoring BIOS

Phoenix Phlash allows you to update or restore the BIOS by using a floppy disk without having to install a new ROM chip.

ETX-P3/C3 User’s Guide 45 Appendix C: BIOS Operation

Kontron

1) Download Phoenix Phlash as a compressed file, CRISMOD6.ZIP, from the Kontron Embedded Modules Web site. It contains the following files:

File Purpose

MAKEBOOT.EXE Creates the custom boot sector on the Crisis Recovery Diskette.

CRISBOOT.BIN Serves as the Crisis Recovery boot sector code.

MINIDOS.SYS Allows the system to boot in Crisis Recovery Mode. PHLASH.EXE Programs the Flash ROM.

WINCRISIS.EXE Creates the Crisis Recovery Diskette from Windows.

WINCRISIS.HLP Serves as the help file of WINCRISES.EXE. PLATFORM.BIN Performs platform-dependent functions.

BIOS.ROM Serves as the actual BIOS image to be programmed into Flash ROM.

2) To install Phoenix Phlash on a hard disk, unzip the content of CRISMOD6.ZIP into a local directory such as C:\PHLASH.

Note: Crisis Recovery requires an external floppy disk controller (ISA adapter card) or a floppy drive connected to the

LPT interface (external floppy drive_1).

Appendix C: BIOS Operation 46 ETX-P3/C3 User’s Guide

Kontron

3) To create a Crisis Recovery Diskette, insert a blank diskette into Drive A: or B: and execute WINCRISIS.EXE. This copies four files onto the Crisis Recovery Diskette.

File Purpose

MINIDOS.SYS Allows the system to boot in Crisis Recovery Mode.

PHLASH.EXE Programs the Flash ROM.

PLATFORM.BIN Performs platform-dependent functions.

BIOS.ROM Serves as the actual BIOS image to be programmed into Flash

ROM.

4) If the BIOS image (BIOS.ROM) changes because of an update or bug fix, copy the new BIOS.ROM image onto the diskette.

5) Phoenix Phlash runs in one of two modes: Command Line or Crisis Recovery. Use the Command Line mode to update or replace a BIOS. To execute Phlash in this mode, move to the Crisis Recovery Disk and type PHLASH. Phoenix Phlash will update the BIOS. Phlash can fail if the system uses memory managers. If this occurs, the utility displays the following message:

Cannot flash when memory manager are present.

14.11 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.

For further information on the update key and the crisis diskette, see application note Phlash_EC_E1xx.pdf, which is available from the Kontron Embedded Modules Web site at

16. APPENDIX E: 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.

Kontron

16.1 JIDA Information

To obtain information about boards that follow the JIDA standard, use the following procedure.

1) 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.

2) 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.

3) 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 jidai110.zip folder, which is available from the Kontron Embedded Modules Web site, for further information on implementing and using JIDA calls with C sample code.

17.3.2. Serial ATA

Serial AT Attachment (ATA) Working Group This X3T10 standard defines an integrated bus interface between disk drives and host processors. It provides a common point of attachment for systems manufacturers and the system. You can search for information about the working group on the Web. We recommend you also search the Web for information on 4.2 I/O cable, if you use hard disks in a DMA3 or PIO4 mode.

The EIA-232-E standard specifies the interface between (for example) a modem and a computer so that they can exchange data. The computer can then send data to the modem, which then sends the data over a telephone line. The data that the modem receives from the telephone line can then be sent to the computer. You can search for information about the standard on the Web.
