Product Description
The MB893 LGA 775 Pentium®4 motherboard incorporates the Intel®
i915GV chipset that can utilize a single LGA775 processor of up to
3.8GHz or higher and supports FSB frequency of 533/800MHz
(133MHz, and 200MHz HCLK respectively).
The i915GV chipset is designed for use with the Pentium®4 processor
with 1M Level 2 (CPU integrated) cache. The integrated MCH
component provides the CPU interface, DDR interface and Hub
Interface.
Four DDR memory sockets supports DDR 400/333 SDRAM DIMM
modules of up to 4GB in capacity.
The board is designed with four Marvell 88E8053 PCI Express Gigabit
LAN single controllers and two Intel®82541PI PCI Gigabit LAN single
controllers. ICH6 supports only one primary IDE interface for UDMA
33/66/100 .Two Serial ATA connectors offer 1.5 Gigabits/sec data
throughput speed - faster than the most advanced parallel ATA.
On board expansion is provided by one Mini PCI socket. Additional
expansion is provided by two PCI slot if the board is used with the IP320
backplane bridge board. Other advanced features include two USB 2.0
ports…etc. Dimensions of the board are 12.6” by 7.2”.

Installing the CPU
The MB893 motherboard supports an LGA 775 processor socket for
Intel® Pentium® 4 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.
