Introduction
Product Description
The MB870 Pentium 4 Mini ITX board incorporates the ATI RS300M
chipset and supports 478-pin Intel Pentium 4 processors of 2GHz and up
to 3.2GHz+ with FSB 800MHz/533MHz/400MHz. MB870 supports the
Pentium 4 processor with 256-KB L2 cache, Pentium 4 processor with
512-KB L2 cache on 0.13 micron process.
The I/O functions are on MB870 integrated onto the IXP150. It supports
the integrated graphics processor (IGP) on the IGP9180. The IGP has
3D, 2D, and video capabilities. The system memory size can be up to
1GB, using the single DDR socket on board. Four USB ports are
supported with the USB 1.1/2.0 standard.
MB870 supports TV out and LVDS with the use of the ATI RS300M
integrated graphics device that accepts two digital graphics input data
streams. One data stream outputs through an LVDS transmitter to an
LCD panel, while the other data stream is encoded for NTSC or PAL TV
and outputs through a 10-bit high speed DAC. The TV encoder device
encodes a graphics signal up to 1024x768 resolution and outputs the
video signals according to NTSC or PAL standards. The LVDS function
supports 18 bit single and dual channel LCD panels.
*The board does not support 24-bit single and dual channel LCD
panels.
The MB870 Mini ITX SBC supports CRT VGA interface as well as TV
out and LVDS interface. Realtek LAN 8100BL supports Ethernet
functionality (10/100Mb). The board also has AC97 6CH audio, 4 COM
ports, UDMA 100, 4 USB ports, two serial ATA ports, watchdog timer
and a PCI slot for expandability. Dimensions of the board are 170mm x
170mm.
This board represents the perfect choice for those who want superior
performance for POS, kiosk, ATM, Web payphone, medical and other
embedded applications.

Installing the CPU
The MB870 embedded board supports a Socket 478 processor socket for
Intel Pentium 4 processors.
The Socket 478 processor socket comes with a lever to secure the
processor. Raise this lever to about a 90°angle to allow the insertion of
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, return the
lever to the lock position. Refer to the figures below.
After you have installed the processor into the socket, check if the
jumpers for the CPU type and speed are correct.
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.

MB870 User’s Manual 7
Installing the Memory
The MB870 embedded board supports one DDR memory sockets for a
maximum total memory of 1GB in DDR memory type. The memory
module capacities supported are 128MB, 256MB, 512MB and 1GB. The
following table lists the supported DDR DIMM configurations. ATI
RS300M supports configurations defined in the JEDEC DDR DIMM
specification only. Non-JEDEC standard DIMMs such as double-sided
x16 DDR SDRAM DIMMs are not supported.
Installing and Removing Memory Modules
To install the DDR modules, locate the memory slot on the embedded
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.
2. Gently push the DDR module in an upright position until the clips of
the slot close to hold the DDR module in place when the DDR module
touches the bottom of the slot.
3. To remove the DDR module, press the clips with both hands.
