Chapter 1 - Introduction The IMC-A2PCI computer system offers a rugged solution for a dedicated industrial controller system with an installed Atom processor for fanless operation. The IMC-A2PCI is targeted at the mining and vehicular industries where a rugged design is required to survive the extreme temperatures and high shock and vibration environments. The construction starts with a finned extruded aluminum housing. This robust design allows fanless operation and provides high structural strength. The Intel Atom N270 Processor, running at 1.6GHz, provides ample performance for the intended environment. The Atom processor line is Intel’s ultra-low power offering. The system supports two plug-in PCI cards. An included watch dog timer will generate a system reset on a software programmable time interval for failsafe operation. System I/O is very robust offering VGA and S-Video for graphics, an audio output, four USB 2.0 and four RS232 connectors. One of the RS232 ports can be configured for RS232, RS422 or RS485. A PS/2 keyboard/mouse connector or one of the USB ports can be used for a keyboard and mouse. Storage options include a Compact Flash slot, a PCMCIA slot and an internal shock isolated 2-1/2” hard drive. Input power is 9 VDC (@1.91A) to 30VDC (@0.69A). An external universal input AC adapter provides 90 to 240VAC operation. The DC input allows direct connection to vehicular systems, either 12VDC or military 28VDC. Environmentally, the unit is rated for –15 to +55 Deg C operating and 5G rms for 5 to 500Hz (random) with a Compact Flash drive (CFD) or 1G rms, 5 to 500Hz if a hard drive is installed. Shock is specified at 50G peak (11mS duration) with a CFD or 20G with a hard drive installed. The system has been tested to CE and FCC Class B

Page 25

Chapter 3 – Award Bios Setup

System Test and Initialization These routines test and initialize board hardware. If the routines encounter an error during the tests, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and non-fatal. The system can usually continue the boot up sequence with non-fatal errors. Non-fatal error messages usually appear on the screen along with the following instructions: Press <F1> to RESUME Write down the message and press the F1 key to continue the boot up sequence.

System configuration verification These routines check the current system configuration against the values stored in the CMOS memory. If they do not match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory. There are three situations in which you will need to change the CMOS settings:

1. You are starting your system for the first time 2. You have changed the hardware attached to your system 3. The CMOS memory has lost power and the configuration information has been erased.

The IMC-A2PCI CMOS memory has an integral lithium battery backup for data retention with an anticipated 7 year life.

Award BIOS Setup The Award BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed CMOS RAM so that it retains the Setup information when the power is turned off. Entering Setup

Power on the computer and press <Del> immediately. This will allow you to enter Setup.

Chassis Plans IMC-A2PCI Technical Reference Chapter 4 – Driver Installation

Page 27

Chapter 4 - Driver Installation The IMC-A2PCI comes with a CD-ROM that contains all drivers and utilities that meet your needs. Follow the sequence below to install the drivers:

Step 1 – Install INF Driver Step 2 – Install VGA Driver Step 3 – Install LAN Driver Step 4 – Install Audio Driver

USB 2.0 Drivers are available for download using Windows Update for both Windows XP and Windows 2000. For additional information regarding USB 2.0 support in Windows XP and Windows 2000, please visit www.microsoft.com/hwdev/usb/. Please read instructions below for further detailed installations.

Installation Insert the IMC-A2PCI CD-ROM into the CD-ROM Drive. The Autorun program should run automatically depending on the Windows settings. You also can choose the drivers to install from step 1 to step 4 in order as following instructions. Step 1 – Install INF Driver

1. Click on the Step 1-INF folder and then double click on the Setup.exe 2. Follow the instructions that the window will show you 3. The system will help you install the driver automatically

Step 2 – Install VGA Driver

1. Click on the Step 2-VGA folder and select the OS folder your system is 2. Double click on the Setup.exe located in each OS folder 3. Follow the instructions that the window shows you 4. The system will help you install the driver automatically

Caution: In products with Intel embedded graphics chipset, when the system is booting before the CRT / LCD monitor has connected to VGA, it will cause the Intel graphics chipset to automatically detect without CRT / LCD connection and set the CRT output to disabled. Therefore, the CRT / LCD screen will go black and never recover in Windows. This is a limitation of the application for the Intel embedded graphics driver under Windows XP. There is a simply way to recover CRT / LCD output through a Hot-Key function as suggested by Intel as follows:

You need to press <CTRL><ALT><F1> key simultaneously to recover the VGA output again. This hot-key function is only in the Windows driver version 6.14.10.4497 or later.

Step 3 – Install LAN Driver

1. Click on the Step 3-LAN folder and select the OS folder your system is 2. Double click on the .exe file located in each OS folder 3. Follow the instructions that the window shows you 4. The system will help you install the driver automatically

Step 4 – Install Audio Driver

1. Click on the Step 4-AC97 folder and then click on the folder of Win98ME2KXP 2. Double click on the wdm_a371.exe 3. Follow the instructions that the window shows you 4. The system will help you install the driver automatically

Chassis Plans IMC-A2PCI Technical Reference Chapter 4 – Driver Installation

Page 28

Note: Under the Window OS environment, if the CRT connector is connected to display monitor by the data switch device, the user need to set the color and resolution from Intel Graphic utility (VGA driver) instead of setting from the control panel in case of the wrong display appearance.

Chassis Plans IMC-A2PCI Technical Reference Appendix A – Watchdog Timer

Page 29

Appendix A - Programming the Watchdog Timer

Programming

The IMC-A2PCI utilizes an ITE 8712 chipset as its watchdog timer controller. A Watchdog Timer is a device that will cause a system reset if not “pinged” within a set period. The “ping” comes from the user’s software. Thus, should the system lock up, the software will not ping the Watchdog Timer which will cause a system reset to reestablish normal operation.

Below are the procedures to complete its configuration and the CHASSIS PLANS intial watchdog timer program is also attached based on which you can develop customized program to fit your application.

Configuring Sequence Description

After the hardware reset or power-on reset, the ITE 8712 enters the normal mode with all logical devices disabled except KBC. The initial state (enable bit ) of this logical device (KBC) is determined by the state of pin 121 (DTR1#) at the falling edge of the system reset during power-on reset.

Figure 31 – Watchdog Timer Flow Chart


Page 30

There are three steps to complete the configuration setup:

1. Enter the MB PnP Mode;

2. Modify the data of configuration registers;

3. Exit the MB PnP Mode. Undesired result may occur if the MB PnP Mode is not exited normally.

1 - Enter the MB PnP Mode

To enter the MB PnP Mode, four special I/O write operations are to be performed during Wait for Key state. To ensure the initial state of the key-check logic, it is necessary to perform four write opera-tions to the Special Address port (2EH). Two different enter keys are provided to select configuration ports (2Eh/2Fh) of the next step.

2 - Modify the Data of the Registers

All configuration registers can be accessed after entering the MB PnP Mode. Before accessing a selected register, the content of Index 07h must be changed to the LDN to which the register belongs, except some Global registers.

3 - Exit the MB PnP Mode Set bit 1 of the configure control register (Index=02h) to 1 to exit the MB PnP Mode.

WatchDog Timer Configuration Registers

Configure Control (Index=02h)

This register is write only. Its values are not sticky; that is to say, a hardware reset will automatically clear the bits, and does not require the software to clear them.
