The CMi37786HX cpuModule
The PC/104 cpuModules described in this manual are designed for industrial applications which re-
quire:
• software and hardware compatibility with the PC/AT world
• high-speed “number-crunching” operation
• low power consumption
• small physical dimensions
• high reliability
• good noise immunity
This cpuModule is highly integrated, combining all major functions of a PC/AT computer on one
compact board. It integrates all primary I/O functions of a AT compatible computer:
• SVGA controller
• Analog SVGA and Digital TFT outputs
• UltraDMA 33/66/100 EIDE Controller
• a keyboard interface
• parallel port
• two versatile RS232/422/485 serial ports
• a Real Time Clock
• a speaker port
• a PS/2 mouse port
• two USB ports
It also enhances standard AT-compatible computer systems by adding:
• Solid State Disk socket
• Non-volatile configuration without a battery
• Watchdog Timer
• Fail Safe Boot ROM
• A multiPort that can be configured as an ECP/EPP Parallel Port, 18 bit digital I/O, or Flop-
py Drive port

A simplified block diagram of the cpuModule is shown in Figure 1.
Figure 1: CMi37786HX Block Diagram
You can easily customize the cpuModule by stacking PC/104 modules such as video controllers,
modems, LANcontrollers, oranaloganddigitaldataacquisitionmodules.StackingPC/104modules
on the cpuModule avoids expensive installations of backplanes and card cages and preserves the
module's compactness.
RTD Enhanced Award BIOS is also implemented in the cpuModule. This BIOS supports ROM-
DOS™, MS-DOS, Linux, and Windows operating systems. Drivers in the BIOS allow booting from
floppy disk, hard disk, Solid State Disk, boot block flash, or DiskOnChip®, thus enabling the system
to be used with traditional disk drives or non-mechanical drives.
The cpuModule and BIOS are also compatible with most real-time operating systems for PC com-
patible computers, although these may require creation of custom drivers to use the SSD and watch-
dog timer.

CHAPTER 2: GETTING STARTED
For many users, the factory configuration of the cpuModule can be used
to get a PC/104 system operational. If you are one of these users, you can
get your system up and running quickly by following a few simple steps
described in this chapter. Briefly, these steps are:
• Connect power.
• Connect the utility cable.
• Connect a keyboard.
• Default BIOS Configuration
• Fail Safe Boot ROM
• Connect a VGA monitor to the SVGA connector.
Refer to the remainder of this chapter for details on each of these steps.

Basic Connector Locations
The following figure and table show the connectors used in this chapter
Figure 2: CMi37786HX Basic Connector Locations
For a complete listing of connectors, please refer to Connector Locations on page 24.
NOTE! Pin 1 of each connector is indicated by a square solder pad
on the bottom of the PC board and a white square silk-
screened on the top of the board.

CMi37786HX RTD Embedded Technologies, Inc.
11
Fail safe boot ROM
Fail Safe Boot ROM is supplied with the board. This feature is programmed into a surface mount
flash chip. The programmed boot ROM is ROM-DOS™. Fail Safe Boot ROM allows the system
to boot without any attached storage devices. i.e. floppy, IDE, SSD. Installing jumper JP5 will force
the cpuModule to use fail safe boot ROM, as well as load the default BIOS settings. This configu-
ration allows you to boot to non-volatile onboard ROM-DOS™.
