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.
