INTRODUCTION

IB891 User’s Manual 1

Introduction

Product Description

The IB891 is a 3.5-inch single board computer based on a two-chip the
Intel® Atom™ single-core N450 or dual-core D510 processor. The
processors come integrated with both a memory controller and an IGP
graphics core with 200MHz (N450) and 400MHz (D510) of GPU
frequency. The IB891 performs with low power consumption and better
hardware decode on graphics intensiv e and multimedia applications fo r
the digital signage, POS/kiosk, automation and other fanless and
low-noise embedded applications.

Measuring 102mm x 147mm, the IB891 has a 3D-capable built-in
Intel® graphics engine that support DirectX 9 and OpenGL 1.4, with an
18-bit single channel LVDS interface and a VGA CRT port edge
connector. The board offers essential features and high-speed
connectivity including two gigabit LAN, watchdog timer, digital I/O,
eight USB 2.0 ports, four serial ports and CF socket. Expansion is
provided by a Mini PCI-e connector that can be used for wireless LAN
or TV-tuner modules.

connectors on the IB891 in order to set up a workable system. The topics
covered are:

Installing the Memory ........................................................................... 6

Setting the Jumpers ................................................................................ 7

Connectors on IB891 ........................................................................... 11

INSTALLATIONS

Installing the Memory

The IB891 board supports one DDR667 DDR2 memory.

Remarks:

N450 supports SO-DIMM x 1 (w/o ECC), Max. 2GB , Single channel
D510 supports SO-DIMM x 1 (w/o ECC), Max. 2GB , Single channel

Installing and Removing Memory Modules

To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:

1. Hold the DDR2 module so that the key of the DDR2 module aligns
with that on the memory slot. Insert the module into the socket at a
slight angle (approximately 30 degrees). Note that the socket and
module are both keyed, which means that the module can be installed
only in one direction.

2. To seat the memory module into the socket, apply firm and even
pressure to each end of the module until you feel it slip down into the
socket.

3. With the module properly seated in the socket, rotate the module
downward. Continue pressing downward until the clips at each end
lock into position.

4. To remove the DDR2 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 adds virus and 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 co mputer, 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.

Note:

If the system cannot boot after making and saving system
changes with Setup, the AMI BIOS supports an override to
the CMOS settings that resets your system to its default.

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.

C. 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.
