Introduction
Product Description
The MB894 Pentium®M Micro ATX motherboard incorporates the
Intel®advanced 855GME Chipset that supports processors from
600MHz to 2.0MHz in 479-ball Micro-FCBGA package with a front
size bus of 400MHz.
Graphics display functionality is provided by the integrated-chipset
VGA controller that supports CRT display and LVDS interface with
24-bit panel specifications. Ethernet connectivity comes from the
ICH4-integrated Ethernet 10/100 Ethernet controller and an optional
secondary LAN using a Realtek 8110S-32 Gigabit Ethernet.
Two DDR DIMM sockets supports up to 2GB of memory. Four COM
ports are supported, with the Winbond W83627HF and Finktek F81216
multi I/O chipsets. There are two IDE connectors –IDE1 supporting
UDMA33/66/100 and IDE2 a CF Type II socket for its slave channel.
Other I/O features include watchdog timer, 4-in/4-out digital I/O, and
two USB ports on board and four USB ports using pin headers.
Expansion slots composed of three PCI, one ISA and one mini PCI slot.
The board uses a 20-pin ATX power.

Installing the CPU
The MB894 motherboard supports a Socket 479processor socket for
Intel®Pentium®M or Celeron®M processors.
The processor socket comes with a screw to secure the processor. As
shown in the left picture below, loosen the screw first before inserting
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, fasten the
screw. Refer to the figures below.
After you have installed the processor into the socket, check if the
jumpers for the CPU type and speed are correct.
