INTRODUCTION
IB895 User’s Manual 1
Introduction
Product Description
The IB895 is a 3.5-inch single board computer based on the Intel® Atom
Cedarview chipset. The Cedar Trail is a platform that uses the Intel
Cedarview-D or Cedarview -M Processor and Intel NM10 Express
Chipset family in the desktop platforms.
The role of the processor in the system is to manage the flow of
information between the following interfaces: DDR3 System Memory
interface, DVI display interface, VGA graphics interface, Low Voltage
Differential Signaling (LVDS) and the Direct Media Interface (DMI). The
processor supports single channel, one DDR3 SODIMMs.
The Intel® processors provide advanced performance in both computing
and graphics quality. This meets the requirement of customers in the
gaming, POS, digital signage and server market segment.
The processor is built on 32-nanometer Hi-K process technology with
Micro-FCBGA11 packaging.
IB895 FEATURES:
Supports Intel® Cedarview -D and Cedarview-M processors
One DDR3 SO-DIMM, 800/1066 MHz, Max. 2GB/4GB
memory*
Integrated Graphics for DVI-I, LVDS displays
2 x SATA Connector
4x COM Port Connector
2 x Mini-PCIe(x1) slot (w/ USB support)
2x GbE (RJ-45) Connector
1x 24V to 12V DC-IN Power Connector
* Note: IB895 with Intel Atom D2550 supports up to 4GB memory
and IB895N with Intel Atom N2600 supports up to 2GB memory.

Installing the Memory
The IB895 board supports one DDR3 memory socket for a maximum
total memory of 2GB or 4GB DDR3 memory type.
Note: IB895 with Intel Atom DC D2550 supports up to 4GB and
IB895N with Intel Atom DC N2600 supports up to 2GB.
Installing and Removing Memory Modules
To install the DDR3 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR3 module so that the key of the DDR3 module aligned
with that on the memory slot.
2. Gently push the DDR3 module in an upright position until the clips of
the slot close to hold the DDR3 module in place when the DDR3
module touches the bottom of the slot.
3. To remove the DDR3 module, press the clips with both hands.

BIOS Introduction
The BIOS (Basic Input/Output System) installed in your computer
system’s ROM supports Intel processors. The BIOS provides critical
low-level support for a standard device such as disk drives, serial ports
and parallel ports. It also password protection as well as special support
for detailed fine-tuning of the chipset controlling the entire system.
BIOS Setup
The BIOS provides a Setup utility program for specifying the system
configurations and settings. The BIOS ROM of the system stores the
Setup utility. When you turn on the computer, the BIOS is immediately
activated. Pressing the <Del> key immediately allows you to enter the
Setup utility. If you are a little bit late pressing the <Del> key, POST
(Power On Self Test) will continue with its test routines, thus preventing
you from invoking the Setup. If you still wish to enter Setup, restart the
system by pressing the ”Reset” button or simultaneously pressing the
<Ctrl>, <Alt> and <Delete> keys. You can also restart by turning the
system Off and back On again. The following message will appear on the
screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to select,
the <PgUp> and <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.
BIOS SETUP
IB895 User’s Manual 21
Warning:
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both AMI and your system manufacturer
to provide the absolute maximum performance and
reliability. Changing the defaults could cause the system to
become unstable and crash in some cases.

D. Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sorts of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user will
restart the WDT at regular intervals before the timer counts to zero.
