INTRODUCTION

Introduction

Product Description

The MI920 Mini ITX board incorporates the Mobile Intel® 910GML/915GM Express Chipset for Embedded Computing, consisting of the Intel® 910GML/ 915GM Graphic Memory Controller Hub (GMCH) and Intel® I/O Controller Hub 6-M (ICH6-M), is an optimized integrated graphics solution with a 400/533MHz 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 Intel® Pentium M/ Celeron® M processors on 130nm or 90nm process. With one DIMM socket on board, the board supports up to 1GB of DDR2 system memory (400MHz for 910GML, 400/533MHz for 915GM chipset).

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.

The main features of the board are:

Supports Celeron® M processors, 400MHz FSB (910GML chipset)

Supports Socket 479, 533/400MHz FSB (915GM chipset)

One DDRII SDRAM DIMM supports up to 1GB of DDR2 400MHz (910GML chipset), DDR2 400/533MHz (915GM chipset)

Onboard 10/100 BaseT and Marvell PCI-Express Gigabit LAN

Intel® 915 Express VGA for CRT, SDVO port supports LVDS and DVI / LVDS

2x SATA, 6x USB 2.0, 4x COM, Watchdog timer

1x PCI, 1x MiniPCIe, CF socket, DC-in for +12V input

Dimensions of the board are 170mm x 170mm.

Ordering Information:

MI920F: Socket 479, 915GM, ICH6M, supports DVI, LVDS, 1x 10/100 LAN, 1x Gigabit LAN, Mini PCI-E

MI920L-C6K: Celeron M 600M/512K , 910GML, ICH6M, supports DVI, LVDS, 1x 10/100 LAN

INSTALLATIONS

Installing the CPU

The MI920 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

Installing the Memory

The MI920 board supports one DDR2 memory socket for a maximum total memory of 1GB 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 DDR2 module touches the bottom of the slot.

3.To remove the DDR2 module, press the clips with both hands.
