Introduction
Product Description
The MB892 Pentium
®
M 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 W83877 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 two Serial ATA ports, watchdog timer, 1394
firewire, 4-in/4-out digital I/O, DiskOnChip socket, and two USB ports
on board and four USB ports using pin headers. Expansion slots
composed of four PCI, two ISA and one AGP 4X slot. The board uses a
20-pin ATX power.

INSTALLATIONS
Installing the CPU
The MB892 motherboard supports a Socket 479 processor 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.
