IDE Devices
Up to two IDE devices can be connected to the POC board. One
cable is included in this kit. The cable accommodates the included
hard drive and one other IDE device, such as a CD-ROM drive or
another hard drive.
Network Adapter
An Intel® 82551 QM Ethernet Controller is included in the
development kit. A CAT-5 cable with an RJ-45 connector is
required to connect this Ethernet adapter to local area network.
AT Power Supply An AT power supply is required in order to power up the board. If
you are using an ATX power supply see Section 2.2 for details on
how to make ATX work.
Memory
One module of 200-pin DDR2 400 MHz SODIMM (max 1 GByte) is
required.
Other Devices
and Adapters
Many PC-compatible peripherals can be attached and configured to
work with the POC board. For example, installing an additional
network adapter into the mini PCI slot. Procuring and installing any
drivers required for additional devices will need to be done by user.
2.2
Setting up the Intel® ECX POC Board
Gather the hardware described in section 2.1 and follow the steps below to set up the POC
board. This manual assumes the user is familiar with basic concepts of installing and
configuring hardware for an x86 architecture platform.
1. Ensure a static free work environment. Static-free procedures must be completed
before removing any components from various anti-static packaging. The POC board
is susceptible to electrostatic discharge (ESD), which may cause product failure or
unpredictable operation.
Caution: Connecting the wrong cable or reversing a cable may damage the POC board and may
damage the device being connected. Since the board is not in a protective chassis, use caution
when connecting cables to this product.
Installation Guide for POC Board
2. Verify contents. Inspect the contents of your kit, and ensure that everything listed in
Section 1.3 is included. Check for damage that may have occurred during shipment.
3. Check jumper settings. Verify that the following jumpers are set in their default state
(see Table 3).

4. Verify installed hardware. Make sure the following hardware is populated on your
POC board:
−
One on-board Intel Intel® Celeron® M Processor Ultra Low Voltage 373 processor in
the 479-ball µFCBGA package
−
−
−
BIOS FWH
Battery
Heatsink
Note:
The above hardware should have been correctly installed at the factory. If they are not
installed correctly, DO NOT power on the board. Correctly re-install the components before
proceeding.
5. Install memory. Install the SODIMM in memory slot DIMM1. Insert the SODIMM
above the slot (the DIMM is keyed so that it only fits in the slot in one orientation).
Firmly, but carefully, insert the SODIMM into the slot until the tabs close.

Installation Guide for POC Board
6. Install storage devices. There is one IDE and one SATA connector on the POC
board, which supports up to 3 hard drives (two PATA IDE devices—a master and a
slave and one SATA IDE device.
Note:
Master/slave settings are determined by a jumper on each IDE device. Consult the device
label/documentation to verify that the jumper is set correctly for the configuration you
choose. A CD-ROM drive or additional hard drive may be installed as a primary slave
device.
Warning:
Failure to properly align the IDE cable may damage the POC board and/or the hard drive.
7. Install the CD-ROM drive
a) Verify that the jumper on the CD-ROM drive is set for slave.
b) Connect the unused end of the IDE cable you have already attached to the
POC board to the CD-ROM drive. Ensure that the cable tracer is aligned with
pin 1 of the CD-ROM drive connector.
c) Connect the four-pin power connector from the power supply to the CD-ROM
drive.
8. Connect the monitor. Connect the monitor cable to the VGA port.
9. Connect the keyboard and mouse. Connect the KB/Mouse cable to the Mini-DIN
PS/2 connector CN13 on the board. Then connect a PS/2 mouse and keyboard to the
KB/Mouse cable. Alternatively, USB keyboard and a USB mouse may be plugged into
one or both of the USB connectors (CN12) on the board. Note that a legacy (PS/2)
keyboard is needed to for entering BIOS setup mode.
Note:
If you connect the USB keyboard and USB mouse to the front panel, you must connect the
USB cable from the front panel to the connector CN5 on the board first.
10. Connect the power supply. Make sure the power supply is turned off and unplugged.
Connect the AT 4P power supply cables to connector CN7 on the board. Next, plug the
power cord into the power supply on the wall.
11. Power up the system. Turn on the monitor and follow by the power supply. Please
refer to Table 19: CN7 for the power supply pin configuration and tap it from ATX
power supply.
Warning:
A loose jumper wire could lead to intermittent power which could damage the board or
cause an electrical short.
Figure 4. 20-pin Power Supply Connector
Installation Guide for POC Board
Notes:
Powering up without all components installed correctly could lead to a power-up failure that
could damage that board. Do not power up the board until the source of any loose
components is fixed and the component has been replaced on the board.
