IB881 User’s Manual 1
Introduction
Product Description
The IB881 3.5-inch disk size SBC incorporates the Intel®advanced
855GME/852GM Chipset that contains two core components: the Memory
Controller Hub (GMCH) and ICH4. The GMCH integrates a 400MHz Pentium®
M processor front side bus controller, integrated graphics controller hub,
integrated LVDS interface, two digital video out ports multiplexed with an AGP
4x controller, a 200/266/ 333MHz DDR-SDRAM controller, and a high-speed
accelerated hub architecture interface for communication with the ICH4.
The ICH4 integrates an Ultra ATA 100/66/33 controller, USB host controller
that supports the USB 1.1 and USB 2.0 specification, LPC interface, FWH Flash
BIOS interface controller, AC’97 digital controller and a hub interface for
communication with the GMCH.
The Pentium M processor is a higher performance, lower power processor with
several microarchitectural enhancements over existing Intel low-power
processors. Some key features of the Pentium M processor microarchitecture
include dynamic execution, data pre-fetch logic, 400MHz source-synchronous
Front Side Bus (FSB), on-die 1 Mbyte second level cache (on-die 512Kbyte
second level cache on Celeron M processor) with advanced transfer cache
architecture, streaming SIMD extensions 2 (SSE2), and Enhanced Intel
SpeedStep technology.
IB881 FEATURES:
-Intel® 82855GME/82852GM chipset
-Supports Intel® Pentium® M, Celeron® M
-SO-DIMM socket supports up to 1GB DDR SDRAM
-10/100 BaseT Ethernet with RJ45 connector
-24-bit LVDS, VGA CRT support
-USB x4, RS232 COM x2, PS/2 Mouse/Keyboard
-IDE x2, FDD, LPT, 12V power connector, PC/104+
-102.24mm x 148.03mm

Installing the CPU
The IB881 board supports a Socket 479 processor socket for Intel®
Pentium®M or Celeron®M processors.
The processor socket comes with a screw to secure the processor. As
shown in the left picture below, loosen the screw first before inserting
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, fasten the
screw. Refer to the figures below.
NOTE: Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.

INSTALLATIONS
IB881 User’s Manual 7
Installing the Memory
The IB881 board supports one SODIMM DDR memory socket for a
maximum total memory. The memory module capacities supported are
128MB, 256MB, 512MB and 1GB.
Installing and Removing Memory Modules
To install the DDR modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR module so that the key of the DDR module align with
those 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 DDR module, press the clips with both hands.
