Product Description

The MI935 Mini-ITX motherboard is designed for either the Intel
Core2 Duo or Core2 Quad processors of up to 1333MHz FSB.
It is based on the Intel’s Q35 Express chipset and it comes with
two single-channel DDR2 memory slots and 4GB memory
capacity for faster system responsiveness and support of 64-bit
computing. The new IBASE motherboards are aimed for high
performance PCs in the digital, communications and industrial
sector.

On board is one PCI Express x16 slot that offers up to 3.5X the
bandwidth over traditional PCI architecture to support the latest
high-performance graphics cards. Dual independent display
comes to life with the onboard Intel Q35 integrated graphics for
CRT and an optional SDVO card supporting either an LVDS or
DVI display interface. LAN functionality is supported with a 10/100
Ethernet controller or with two Gigabit Ethernet controllers.

MI935 is expandable, with the use of an adaptor card, ID394, to
support 2 or 4 serial ports, or ID395 to support TPM 1.2 security
function. Other useful features on the board include two SATA II
ports, one eSATA port, eight USB 2.0 interface, watchdog timer,
digital I/O and two serial ports. Board dimensions are 170mm by
170mm. (Note: CPU power consumption – under 95watt
recommended.)

INSTALLATIONS

Installing the CPU

The MI935 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.
