Thank you for choosing our MX46 motherboard. The MX46 is Intel® Socket 478 motherboard (M/B) based on the Micro ATX form factor
featuring the SIS 650 / SIS 961 chipset
®
Pentium
AGP 4X mode and pipelined spilt-transaction long burst transfer up to 1056MB/sec. According to different customer’s requirements, 128,
256, 512Mb and 1GB DDR SDRAM DIMM modules can be applied to the motherboard and the maximum memory size can be up to 2 GB.
The onboard IDE controller supports Ultra DMA
taking advantage of the Communication and Network Riser (CNR)
single baseboard design. More than that, on the strength of Realtek RTL8100 LAN
controller on board, which is a highly integrated Platform LAN Connect
device, it provides 10/100M bps Ethernet for office and home use
(Optional). Besides, the MX46 has a RealTek ALC201A AC97
chipset onboard providing high performance and magic
CODEC
surround stereo sound to let people enjoy working with it. Now, let’s
enjoy all features from MX46 motherboard.
. As high performance chipset built in the M/B, the MX46 motherboard can support Intel® Socket 478
4 (Willamette / Northwood) and 400 MHz Front Side Bus (FSB) clock. In the AGP performance, it has one AGP slot and supports
33/66/100 mode and the transfer rate up to 100MB/s. Further flexibility can be achieved by
card option that allows audio, modem, and/or LAN configuration on a

Supports Intel® Socket 478 Pentium® 4 (Willamette / Northwood) 1.4GHz~2.4GHz+ with 400MHz Front Side Bus (FSB) designed for Socket
478 technology.
Chipset
The motherboard is equipped with SIS 650 / 961 chipset. SIS 650 chipset consists of host interface Controller and integrated high
performance DDR SDRAM
delivering 533MB/s Bandwidth. In coordination with SIS 650, the SIS 961 chipset integrated fast Ethernet/Home networking controller,
Audio/Modem Controller with AC’97 interface and advanced power management, which can strongly enhance the system performance.
Host system controller, which provide superior performance between the CPU, SDRAM, AGP bus, and
Expansion Slots
Including three 32-bit/33MHz PCI, one CNR and one AGP 1x2x4X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR)
Graphics Port (AGP) specification provides a new level of video display sophistication and speed. The AGP video cards support data
transfer rate up to 1056MB/s. MX46 motherboard includes one AGP expansion slot for a bus mastering AGP graphic card. For AD and SBA
signaling, MX46 motherboard can support 4X mode. Of three PCI slots provided, all of them are master PCI slots with arbitration and

Dr. LED (Upgrade Optional)
The Dr. LED has 8 LEDs on this MX46 M/B to easily show what kind of problems you may encounter.
Power Management/Plug and Play
Supports the power management function that confirms to the power-saving standards of the U.S. Environmental Protection Agency (EPA)
Energy Star program. It also offers Plug-and-Play
user-friendlier.
, which helps save users from configuration problems, thus making the system much
Hardware Monitoring Management
Supports CPU or system fans status, temperature and voltage monitoring and alert, through the on-board hardware monitor module.
Enhanced ACPI
Fully implement the ACPI standard for Windows® 98/ME/2000/XP series compatibility, and supports Soft-Off, STR (Suspend to RAM, S3),
STD (Suspend to Disk, S4) features.
Super Multi-I/O
Provides two high-speed UART compatible serial ports and one parallel port with EPP and ECP capabilities. UART can also be directed
from COM1 to the Infrared Module for the wireless connections.

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.

When you read this online manual and start to assemble your computer system, you may find some of functions are called “Optional”, and
some are called “Upgrade Optional”. Though all AOpen motherboards include many amazing and powerful features, in some situations,
these powerful features are not used to every user. Hence, we changed some key features as “Optional” for you to choose. Some optional
functions that can be upgraded by users, we call them “Upgrade Optional”. As for those optional functions that can’t be upgraded by
ourselves, we call them “Optional”. If needed, you can contact our local distributors or resellers for purchasing “Upgrade Optional”
components, and again you can visit AOpen official web site: www.aopen.com
for more detail information.

This motherboard supports Intel® Pentium 4 Socket 478 series CPU (Willamette / Northwood). Be careful of CPU orientation when you plug
it into CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU
upper interface. Match Pin 1 and cut edge, then insert the CPU into the
socket.

This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, and no jumpers or switches are needed.
The default setting is "table select mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.
Core Frequency = CPU FSB Clock * CPU Ratio
PCI Clock = CPU FSB Clock / Clock Ratio
AGP Clock = PCI Clock x 2
CPU Ratio 10x… 21x, 22x, 23x, 24x
