8 congatec Board Controller The cbc plays an important role for most of the congatec BIOS features. The idea was to fully isolate some embedded features from the x86 core architecture. frees up the x86 CPU System monitoring in Soft Off (S5) mode 100% compatibility amongst all congatec modules The Microcontroller firmware was conceived and fully developed by congatec Congatec AG 8 congatec Board Controller Watchdog I2C Controller EEPROM Power Loss Control Serial No. EAN code HW/FW rev.

12 congatec Board Controller POST Watchdog Allows monitoring of the BIOS POST. Single Event Mode. Supported Event: Hardware Reset. Timeouts from 256 milliseconds to over 4.5 hours. Starts at system power-up or system reset. Can be enabled in the BIOS Setup Congatec AG 12 POST Watchdog Reset Hardware Reset

13 congatec Board Controller Fast Mode I2C Bus Due to the simplicity of the protocol and the high availability of devices, the I²C Bus is a frequently used bus interface in embedded applications. congatec understands this and therefore has chosen to offer a 400kHz multi-master I²C Bus complaint to specification 1.0. Of course it is fully supported by the CGOS API. μcontroller A static RAM / Flash LCD driver SDA SCL I2C Controller ADC 2005 Congatec AG μcontroller B 13

14 congatec Board Controller Power Loss Control Specifies the mode of operation if an AC power loss occurs. Supported Modes: Turn On (Server Mode) Remain Off (Desktop Mode) Last State (restores the previous power state before power loss occurred) Unlike other module designs available in the embedded market, a CMOS battery is not required by congatec modules to support the 'Power Loss Control' feature Congatec AG 14 congatec Board Controller Watchdog I2C Controller EEPROM Power Loss Control Serial No. EAN code HW/FW rev.

15 Embedded BIOS Extensions BIOS CMOS Data Backup A copy of the BIOS CMOS settings is stored in flash memory. If a backup battery is present it will prevent systems from not booting when the backup battery has failed. BIOS Flash 2005 Congatec AG Allows for battery-less applications. ROM BIOS Defaults 15

16 Embedded BIOS Extensions OEM CMOS Default Settings Most embedded module customers need to have their own CMOS ROM default settings. The congatec embedded BIOS allows the customer to store their own defaults in flash memory. This helps to reduce the need for customized BIOS versions. Both, the OEM and ROM default image, are stored in the System BIOS flash part. BIOS Flash OEM BIOS Defaults OEM Defaults have higher priority than ROM Defaults. ROM BIOS Defaults In case OEM Defaults are present, the BIOS always loads the OEM image, not the ROM default image. In case no OEM Defaults are present, the orignial ROM defaults are loaded by the BIOS Congatec AG 16

17 Embedded BIOS Extensions Quiet Boot and Splash Screen In order to hide the PC functionality in an embedded PC application, the BIOS can display a customer logo instead of the traditional diagnostic output during POST. With the congatec embedded BIOS, customers can now integrate an OEM logo into the standard BIOS by themselves Congatec AG 17

18 Embedded BIOS Extensions OEM BIOS Code The congatec embedded BIOS calls OEM code at different times during POST. With the OEM BIOS support, customers can initialize base board hardware components and add boot loaders Congatec AG 18 Boot block congatec Embedded BIOS Allows customers to integrate their own code into the BIOS POST process. CMOS Test Video Initializing... Option ROM scan... Boot OEM Code

19 congatec System Utility congatec Utility for system configuration and customization. Available as Windows and DOS application. File and flash mode support. Supports: OEM CMOS Defaults OEM Logo OEM BIOS Code BIOS Flash Update BC Firmware Update Panel Configuration 2005 Congatec AG 19

20 Embedded BIOS Extensions BIOS write and update protection Function is available after the Supervisor Password was set in the BIOS Setup. When enabled, the BIOS can not be updated with any known BIOS update tools. BIOS write and update protection can be temporarily disabled with the congatec System Utility (CGUTIL) (requires Supervisor Password) Congatec AG 20

21 Embedded BIOS Extensions LCD Detection and Backlight Control By understanding the basic EDID (Extended Display Identification Data) data structure, the congatec BIOS can automatically detect and configure an attached flat panel. It supports panel detection according to the new EPI (Embedded Panel Interface)specification. EPI is a new standard established by several COM manufacturers. EDID is a well known industry standard established by the VESA organization Additionally the Backlight intensity can be set in BIOS setup and also by application software that uses the CGOS API Congatec AG 21

22 Embedded BIOS Extensions Flat Panel EEPROM There are 3 ways to set the right display timing: (LCD or Baseboard) EDID File or Block ID 1. Select a fix timing (e.g. SVGA) in the BIOS setup. +no Eeprom required - no LCD auto-detection 3. Provide a block ID in the panel or on the baseboard. +LCD auto-detection +user can reuse already defined data sets EDID = Extended Display Identification Data 2005 Congatec AG Backlight & Power Sequencing Video Controller congatec Board Controller I2C Interface COM Flat Panel Configuration Video BIOS EDID Wrapper 2. Provide EDID Daten in the panel or on the baseboard. +LCD auto-detection +user can adjust timing Embedded Panel Data Area Autodetect VGA Panel Data SVGA Panel Data XGA Panel Data SXGA Panel Data...

23 Embedded BIOS Extensions ACPI Battery Management The congatec ACPI BIOS and Board Controller are designed to support a CMB (Control Method Battery) sub-system. By following our CMB design guide, customers can implement their own battery solutions or buy a fully tested customized battery system from a congatec partner. In combination with an ACPI OS most of the battery functionality associated with portable computers is now supported on the congatec embedded platform Congatec AG 23

24 congatec Operating System API CGOS API Is an easily programmable interface used to access the congatec Embedded Board features. The API is implemented as a generic and module independent driver. All hardware dependent code is in the BIOS. The API is available for all common OSes like Win32, WinCE, Linux, VxWorks, QNX. CGOS API helps you to reduce the development time. Guarantees software compatibility when a module upgrade is necessary.

25 Advanced BSP's Not only the BIOS but also the BSP's are considered vitally important when devel congatec BSP oping customer specific applications. Device Driver congatec offers its customers these crucial building blocks, which will include Tools both the latest tested drivers from silicon Software vendors and the congatec specific Installation Guide drivers/tools for accessing all of our embedded board features. BSP's will be available for the most common operating systems: On request: VxWORKS 2005 Congatec AG 25

26 Design-In Support First of all, congatec fully understands how important it is in an embedded modules system that both the customer's base board and the embedded PC work together perfectly congatec is also well aware of the fact that there are many firmware aspects customers must consider when designing an embedded module system to ensure that it is done correctly. For these reasons, the congatec team is committed to giving the best design-in support to our customers. This can only be achieved by providing first class product manuals as well as design guides and supplementing that with strong personal engineering support. This is the commitment congatec is prepared to offer customers Congatec AG 26
