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 MB865F 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.

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 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.
