Product Description
The MI940 Mini-ITX motherboard is designed for LGA775
processors such as the Intel Core2 Duo, and Pentium D /
Pentium 4 processors with up to 800MHz FSB. It is based on the
Intel’s 945GC Express chipset and it comes with two DDR2
memory slots and 2GB memory capacity for faster system
responsiveness.
MI940 comes with the Intel 945GC integrated graphics and
Chrontel CH7307 to support for CRT and DVI display interface.
LAN functionality is supported with a Gigabit Ethernet controller.
MI940 is expandable, with the use of an adaptor card, ID394, to
support more serial ports, or ID395 to support TPM 1.2 security
function. Other useful features on the board include four SATA II
ports, six USB 2.0 ports, watchdog timer, digital I/O and two serial
ports. Board dimensions are 170mm by 170mm.

INSTALLATIONS
Installing the CPU
The MI940 motherboard supports an LGA 775 processor socket for
Intel® Core 2 Duo 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
The system power is provided to the motherboard with the ATX2 and
ATX1 power connectors. ATX2 is a 24-pin power connector and ATX1
is a 4-pin 12V power connector.
The 24-pin power connector can to be connected to a standard 20-pin
ATX power connector in a standard ATX power supply (Min. 400watt).
Note: The power supply 5VSB voltage must be at least 2A.
