Introduction
Product Description
The world's first Pentium 4 industrial motherboard, MB800, is based on
the Intel 845G chipset. It packs the key features of the 845G chipset,
including 533MHz processor side bus and integrated LAN and graphics.
The 845G chipset includes Intel's new ICH4 I/O control hub that
supports USB 2.0 with peak transfer rate of up to 480Mbps.
The AGP4X integrated graphics supports interface such as TV out,
LVDS and CRT. It can have up to DVMT 64MB shared memory.
One-channel and dual-channel digital display are supported with
resolutions of up to 1600x1200 and 2048x1536 @ 60Hz respectively.
The MB800 motherboard supports Pentium 4 processors of up to
2.6GHz+ and comes optionally with a secondary LAN that supports
either up to 1000Mb/s (Gigabit LAN) or 100Mb/s data transfer rate. Two
DDR slots on board support up to 2GB of DDR200/266 non-ECC DDR
SDRAM modules. Hardware monitoring is available with the Winbond
W83627HF chipset on board.
Other special features of the board includes 256-level watchdog timer,
DiskOnChip socket, digital I/O (4 in / 4 out) and PCI to ISA bridge.
Measuring 305mm by 244mm, MB800 also has an AGP slot, three PCI
slots, three ISA slots and a MicroPCI socket. With ISA slots on board and
a long life cycle, MB800 is the powerful platform of choice for industrial
applications.

Installing the CPU
The MB800 motherboard 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.

MB800 User’s Manual 7
ATX Power Installation
Power is provided to the MB800 motherboard with the J10 standard ATX
power supply connector and J12 ATX 12V power connector. These two
power connectors should be utilized for the motherboard to function.
MicroPCI Daughter Card Installation
To insert the MicroPCI daughter cards, position it at 30°to the PCB and
gently push it into the MicroPCI connector (See Figure 1 below). The
card will not fit when inserted at an angle of 45°or 15°. Once inserted,
slowly press the card towards the PCB until it locks on both sides to the
clips of the connector. Screw the card to the PCB to secure the
installation. To remove the MicroPCI card, pull the ‘clips’ sideways as
shown in Figure 2 below.

Installing the Memory
The MB800 motherboard supports two DDR memory sockets for a
maximum total memory of 2GB in DDR memory type. The memory
module capacities supported are 64MB, 128MB, 256MB, 512MB and
1GB. The following table lists the supported DDR DIMM
configurations. Intel 845G supports configurations defined in the JEDEC
DDR DIMM specification only (A,B,C). 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 motherboard
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.

Configuring the CPU Frequency
The MB800 motherboard does not provide DIP switches to configure the
processor speed (CPU frequency). The CPU frequency and processor side
bus of the processor can be automatically detected by the motherboard.
JP3, JP4, JP5: RS232/422/485 (COM2) Selection
COM1 is fixed for RS-232 use only.
COM2 is selectable for RS232, RS-422 and RS-485.
