All heat generating components are thermally conducted to the heatsink in order to avoid hot spots. Below images illustrate how to install the heat spreader. 1. There is a protective plastic covering on the thermal pads. This must be removed before the heatsinkr can be mounted. 2. Each heatsink is designed for a specific CEM module. The thermal pads on the heatsink are designed to make contact with the necessary components on the CEM module. When mounting the heatsink you must make sure that the thermal pads on the heatsink make complete contact (no space between thermal pad and component) with the corresponding components on the CEM module. This is especially critical for CEM modules that have higher CPU speeds (for example 1.0GHz or more) to ensure that the heatsink acts as a proper thermal interface for cooling solutions. 3. This CPU module has five assembly holes for installing heat spreader plate. Use the five screws to secure the heat spreader plate to the CEM880. Be careful not to over-tighten the screws. Hardware Description 9 CEM880 COM Express 2.4 TM Type 6 Basic Module Switch Settings Properly configure switch settings on the CEM880 to meet your application purpose. Below you can find a summary table of all switches and onboard default settings. Once the default switch setting needs to be changed, please do it under power-off condition. Note Switch Description Setting SW1 PCI-Express Bifurcation Setting Default: One x16 PCI-Express SW1-1 OFF, SW1-2 OFF Auto Power On Default: Disable SW2-1 OFF Restore BIOS Optimal Defaults Default: Normal Operation SW2-2 OFF SW2 2.4.1 PCI-Express Bifurcation Setting (SW1) The SW1 is for PCI-Express bifurcation setting. See table below for detailed information. Function Setting Select one x8 and two x4 PCI-Express SW1-1 ON, SW1-2 ON Select two x8 PCI-Express SW1-1 ON, SW1-2 OFF Reserved SW1-1 OFF, SW1-2 ON Select one x16 PCI-Express (Default) SW1-1 OFF, SW1-2 OFF 2.4.2 Auto Power On and Restore BIOS Optimal Defaults (SW2) If dip1 of SW2 (SW2-1) is enabled for power input, the system will be automatically power on without pressing soft power button. If this jumper is disabled for power input, it is necessary to manually press soft power button to power on the system. The dip2 of SW2 (SW2-2) is for restoring BIOS default status. Flip SW2-2 to ON position for a few seconds then flip it back to OFF position. Doing this procedure can restore BIOS optimal defaults. 10 Function Setting Disable auto power on (Default) SW2-1 OFF Enable auto power on SW2-1 ON Normal operation (Default) SW2-2 OFF Restore BIOS optimal defaults SW2-2 ON Hardware Description CEM880 COM Express 2.5 TM Type 6 Basic Module Connectors Signals go to the other parts of the system through connectors.

All configured parameters are stored in a flash chip to save the setup information whenever the power is turned off. This chapter provides users with detailed description about how to set up basic system configuration through the AMI BIOS setup utility. 4.1 Starting To enter the setup screens, follow the steps below: 1. 2. Turn on the computer and press the <Del> key immediately. After you press the <Del> key, the main BIOS setup menu displays. You can access the other setup screens from the main BIOS setup menu, such as the Advanced and Chipset menus. If your computer cannot boot after making and saving system changes with BIOS setup, you can restore BIOS optimal defaults by setting SW2-2 (see section 2.4.2). Note It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI and your system manufacturer have carefully set up these defaults that provide the best performance and reliability. 4.2 Navigation Keys The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS setup utility hot keys can be used at any time during the setup navigation process. These keys include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on. Some of the navigation keys differ from one screen to another. Note AMI BIOS Setup Utility 21 CEM880 COM Express TM Type 6 Basic Module Hot Keys Description Left/Right The Left and Right <Arrow> keys allow you to select a setup screen. Up/Down The Up and Down <Arrow> keys allow you to select a setup screen or sub-screen. + Plus/Minus The Plus and Minus <Arrow> keys allow you to change the field value of a particular setup item. Tab The <Tab> key allows you to select setup fields. F1 The <F1> key allows you to display the General Help screen. F2 The <F2> key allows you to Load Previous Values. F3 The <F3> key allows you to Load Optimized Defaults. F4 The <F4> key allows you to save any changes you have made and exit Setup. Press the <F4> key to save your changes. Esc The <Esc> key allows you to discard any changes you have made and exit the Setup. Press the <Esc> key to exit the setup without saving your changes. Enter The <Enter> key allows you to display or change the setup option listed for a particular setup item. The <Enter> key can also allow you to display the setup sub- screens. 22 AMI BIOS Setup Utility CEM880 COM Express 4.3 TM Type 6 Basic Module Main Menu When you first enter the setup utility, you will enter the Main setup screen. You can always return to the Main setup screen by selecting the Main tab. System Time/Date can be set up as described below. The Main BIOS setup screen is shown below. BIOS Information Display BIOS information. System Language Use this item to choose the system default language. System Date/Time Use this option to change the system time and date. Highlight System Time or System Date using the <Arrow> keys. Enter new values through the keyboard. Press the <Tab> key or the <Arrow> keys to move between fields. The date must be entered in MM/DD/YY format. The time is entered in HH:MM:SS format. AMI BIOS Setup Utility 23 CEM880 COM Express 4.4 TM Type 6 Basic Module Advanced Menu The Advanced menu also allows users to set configuration of the CPU and other system devices. You can select any of the items in the left frame of the screen to go to the sub menus: ► ► ► ► ► ► ► ► ACPI Settings Trusted Computing CPU Configuration SATA Configuration PCH-FW Configuration USB Configuration H/W Monitor W83627DHG Super IO Configuration For items marked with “”, please press <Enter> for more options. 24 AMI BIOS Setup Utility CEM880 COM Express TM Type 6 Basic Module ACPI Settings You can use this screen to select options for the ACPI configuration, and change the value of the selected option. A description of the selected item appears on the right side of the screen. ACPI Sleep State Select the ACPI (Advanced Configuration and Power Interface) sleep state. Configuration options are Suspend Disabled, S1 only (CPU Stop Clock) and S3 only (Suspend to RAM). The S3 only (Suspend to RAM) option selects ACPI sleep state the system will enter when suspend button is pressed. AMI BIOS Setup Utility 25 CEM880 COM Express TM Type 6 Basic Module Trusted Computing You can use this screen for TPM (Trusted Platform Module) configuration.

Some embedded systems are not watched by human for 24 hours. It is usually too slow to wait for someone to reboot when computer hangs. The systems need to be able to reset automatically when things go wrong. The watchdog timer gives us solution. The watchdog timer is a counter that triggers a system reset when it counts down to zero from a preset value. The software starts counter with an initial value and must reset it periodically. If the counter ever reaches zero which means the software has crashed, the system will reboot. About GPIO The onboard GPIO (general input and output) has 8 bits (GPI0~3 and GPO0~3). In default, all pins are pulled high with +3.3V level (according to main power). The BIOS default settings are 4 inputs and 4 outputs where all of these pins are set to 1. Use these GPIO signals to control cash drawers and sense warning signals from an Uninterrupted Power System (UPS), or perform store security control.
