INTRODUCTION
Introduction
Product Description
The world's first Pentium 4 LGA775 industrial motherboard based on
the Intel® 865G chipset, MB865, supports processor FSB of
533/800MHz for processor speeds of up to 3.8GHz. With two DDR
memory socket on board, the motherboard accommodates a maximum
memory capacity of 2GB. Integrated chipset-graphics features CRT
VGA support with up to 64MB shared memory, while Ethernet
functionality is provided by an Intel® 10/100Mb and an optional
Gigabit Ethernet.
Supporting the latest LGA775 processors, the MB865 supports four
COM ports based on the Winbond I/O chipset on board. A total of six
USB 2.0 ports can be used, as well as two serial ATA ports for high
data transfers. Advanced storage comes in the form of a type 2 Compact
Flash socket.
Interface function is available with one 8X AGP slot, four PCI slots and
two ISA slots. This ATX-form-factor board has dimensions of 305mm
by 244mm. Other features include a watchdog timer and 4-in/4-out
digital I/O.
The board comes in three models, as of this writing – MB865, MB865F
and MB865V. MB865 has 10/100Mb Ethernet, while M B865F has both
10/100Mb and Gigabit Ethernet. MB865V uses the 865GV chipset, has
10/100Mb Ethernet, but without AGP slot.

INSTALLATIONS
Installing the CPU
The MB865 motherboard supports a LGA 775 processor socket for
Intel® Pentium® 4 processors.
The LGA 775 processor socket comes with a lever to secure the
processor. Refer to the pictures below, from left to right, on how to place
the processor into the CPU socket. Please note that the cover of the
LGA775 socket must always be installed during transport to avoid
damage to the socket.
ATX Power Installation
Power is provided to the MB865 motherboard with the ATX1 standard
24-pin ATX power supply connector and J5 ATX 12V power connector.
These two power connectors should be utilized for the motherboard to
function.

INSTALLATIONS
Installing the Memory
The MB865 motherboard supports two DDR memory sockets for a
maximum to tal memory of 2GB in DDR memory ty pe. The memory
module capacities supported are 64MB, 128MB, 256MB, 512MB and
1GB. The following table lists the supported DDR DIMM
configurations. Intel 865G 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.

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 MB865 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.
JP1, JP2, JP3: RS232/422/485 (COM2) Selection
COM1 is fixed for RS-232 use only.
COM2 is selectable for RS232, RS-422 and RS-485. COM3 and COM4
are fixed for RS-232 use only. The following table describes the jumper
settings for COM2 selection.
