Thank you very much for choosing AOpen MK73LE. It is an
AMD®Socket 462 motherboard based on the Micro ATX
form factor featuring the VIA KLE133 chipset. As high
performance chipset built in the M/B, the MK73LE supports
both AMD®Socket 462 series Athlon™ & Duron™
processor in 200MHz Front Side bus (FSB). As to the AGP
performance, it integrates a Trident Blade3D AGP graphics
engine to deliver rich graphics capabilities for running 2D/3D software and Internet applications.
Through its advanced memory controller architecture, this motherboard supports up to 1.0GB of
PC133 SDRAM. The on-board IDE controller supports UltraATA 33/66/100 mode and the
transfer rate up to the latest high-speed 100MB/s. Further flexibility can be achieved by taking
advantage of the Communication and Network Riser (CNR) card option that allows audio or
modem configuration on a single baseboard design. Besides, on the strength of built in AC97
CODEC controller, it can bring you the high quality multimedia capabilities with the magic stereo
surround. Now, enjoy all features from AOpen MK73LE.

CPU
Supports AMD® Socket 462 Athlon®& Duron®600MHz~950MHz+ with 100/133MHz Front Side
Bus designed for Socket 462 technology.
Chipset
The VIA Apollo KLE133 is a high performance, cost-effective and energy efficient chipset for the
implementation of computer system with 100MHz CPU FSB frequencies and based on 64-bit
Socket 462 CPU. The VIA Apollo KLE133 integrates Trident Blade 2D/3D graphic accelerator
into a single BGA package, which provides you the better capabilities for demanding software
and Internet multimedia applications with comprehensive driver support. The VIA Apollo KLE133
provides superior performance between the CPU, DRAM, AGP bus and PCI bus.
Expansion Slots
Including three 32-bit / 33MHz PCI and CNR slots. The PCI local bus throughput can be up to
132MB/s. The CNR (Communication and Networking Riser) slot provided by MK73LE can
support Audio/Modem card CNR interface.

Memory
The MK73LE supports both PC100 and PC133 SDRAM, which allows zero wait state bursting
between the DRAM and the data buffers at 100/133MHz. The two banks of DIMM slots can be
composed of an arbitrary mixture of 1M/2M/4M/8M/16M/32MxN DRAMs. The DRAM controller
can run at either the host CPU bus frequency (66/100/133MHz) or pseudo-synchronous to the
CPU bus frequency.
Onboard Trident Blade3D Graphics Engine
This motherboard integrates the rich AGP graphics capabilities of the Trident Blade3D graphics
engine, which provides full AGP 2.0 capability for maximum bus utilization including 1X/2X/4X
mode transfers, SBA (Side Band Addressing), Flush/Fence commands, and pipelined grants.
The AGP 4X specification provides a new level of video display sophistication and speed. The
AGP 4X video cards support data transfer rates up to 533MB/s.
Ultra ATA 33/66/100 Enhanced IDE
Ultra ATA/100 is the latest version of the ATA hard drive data transfer protocol. This motherboard
comes with an on-board PCI Bus Master IDE controller with two connectors that supports four
IDE devices in two channels, supports Ultra ATA 33/66/100, PIO Modes 3 and 4 and Bus Master
IDE DMA Mode 4, and supports Enhanced IDE devices.

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk
drives, expansion boards, and other components. Always observe the
following precautions before you install a system component.
1. Do not remove a component from its protective packaging until
you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the
system unit before handling a component. If a wrist strap is not
available, maintain contact with the system unit throughout any
procedure requiring ESD protection.

CP PU U I In ns st ta al ll la at ti io on n
This motherboard supports AMD®Athlon and Duron Socket 462 CPU. Beware of CPU orientation
when you plug it into CPU socket.
1. Pull CPU socket lever and up to 90-degree
angle.
2. Locate Pin 1 on the socket and look for a black
dot or cut edge on the CPU upper left. Match Pin
1 and cut edge. Then insert CPU into the socket.
3. Press down CPU socket lever to finish CPU
installation.
Note: If you do not match CPU socke
