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

IB881 User’s Manual

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.

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.

be removed and the female side plugged for 5.0V I/O signals and

Pin-D30 will be modified in the same manner for 3.3V I/O. It is

recommended that both KEY pins (A1 and D30) be electrically

connnected for GND for shielding.
