2. Introduction
The M81E/M81DC2/M812-FX series motherboard offers the high integration, high
performance, high compatibility and power efficient solution on the powerful Intel PPGA370
processors. The motherboard uses the Intel i810E chipset which includes the FW82810/
DC100/E (GMCHO/GMCH/GMCHE) / FW82801AA (ICH) and N82802AB (Firmware Hub)
chip in the Flex ATX form factor.
The principal feature of this motherboard is it can support PPGA370 Celeron and Coppermine
series processors. It operate at 66/100/133MHz FSB and CPU speed running from 300MHz
up to 733MHz.
The i810E chipset provides full AGP capability with the internal 2D/3D graphics engine for
maximum software compatibility, also supports full MPEG-2 motion compensation for
software-assisted DVD video playback and a digital video output that may support (via
Chrontel CH7008A external video Encoder) NTSC and PAL broadcast standards.
The motherboard provides a Mini PCI interface that was developed specifically for integrated
communications peripherals such as modems and network interface card. For customers
who need the flexibility of LAN and modem solutions that can be changed and upgraded by
the end user, PC card may offer a better fitting solution. Also integrated AC97 Audio and 10/
100 Mbps Fast Ethernet LAN solution, which can be configured for either 100Mbps (100Base-
TX) or 10Mbps (10Base-T) Ethernet operation. It provides a RJ-45 port for user to attach
the motherboard, and a phone jack to attach the chassis for modem.
The system management chip (Winbond W83627HF-AW) with software, allows user to
monitor system environment such as system and CPU fan speed (requires fan with
tachometer output), CPU temperature , system temperature and operating voltages.
The motherboard has a comprehensive set of integrated I/O ports. The I/O port array
features PS/2 Keyboard and Mouse ports, a Parallel port, five USB ports, a RJ-45 port, a
VGA display port, a Audio port, a Serial ports, an Infrared port (for IrDA or ASKIR) and two PCI
IDE, also has two 168-Pin DIMM sockets for the installation 3.3V unbuffered SDRAM module, it
supports a memory bus of 100MHz, so we recommend you can choose PC-100 compliant for
performance and upgrade required.
The fully programmable firmware enhances the system feature like Plug and Play, APM (v1.2)/
ACPI (v1.0), Modem Ring-On, Wake On LAN, control of DPMS and BIOS upgrade ability.
