INTRODUCTION
Introduction
Product Description
The IB868 PICMG1.3 SHB board incorporates the Mobile Intel® 915GM
Express Chipset for Embedded Computing, consisting of the Intel® 915GM
Graphic Memory Controller Hub (GMCH) and Intel® I/O Controller Hub 6-M
(ICH6-M), is an optimized integrated graphics solution with a 400 MHz and 533
MHz front-side bus.
The integrated 32-bit 3D graphics engine, based on Intel® Graphics Media
Accelerator 900 (Intel® GMA 900) architecture, operates at core speeds of up to
320 MHz. It features a low-power design, is validated with the Intel® Pentium® M
and Intel® Celeron® M processors on 90nm process. With two DIMM socket on
board, the board supports up to 2GB of DDR2 533 MHz system memory.
Intel® Graphics supports a unique intelligent memory management scheme called
Dynamic Video Memory Technology (DVMT). DVMT handles diverse
applications by providing the maximum availability of system memory for general
computer usage, while supplying additional graphics memory when a 3D-intensive
application requests it. The Intel GMA 900 graphics architecture also takes
advantage of the high-performance Intel processor. Intel GMA 900 graphics
supports Dual Independent Display technology.

Installing the CPU
The IB868 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 so cket 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:
6IB868 User’s Manual
Ensure that the CPU heat sink and the CPU
cause your system to hang or be unstable.
INSTALLATIONS
Installing the Memory
The IB868 board supports two DDR2 memory socket for a maximum
total memory of 2GB in DDR2 memory type.
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 align with
those on the memory slot.
2. Gently push the DDR2 module in an upright position until the clips of
the slot close to hold the DDR2 module in place when the DDR
module touches the bottom of the slot.
3. To remove the DDR2 module, press the clips with both hands.
