Thank you for choosing AOpen MX4LS motherboard. MX4LS is Intel®Socket 478 motherboard (M/B) based on the Micro-ATX
form factor featuring the Intel® 845GL(Brookdale) chipset. As high performance chipset built in the M/B, MX4LS motherboard
support Intel®Socket 478 Pentium®4 (Brookdale) and 400 MHz Front Side Bus (FSB) clock. On the strength of Intel 845GL
chipset, this motherboard multiplexes the AGP signal interface with two Intel DVO ports that are capable of supporting a variety
of digital display devices such as TV-Out encoders. According to different customer’s requirements, the Intel 845GL chipset
memory interface supports PC100/133 SDRAM devices with densities of 64, 128, 256, 512MB or 1GB SDRAM DIMM modules
and the maximum memory size can be up to 2 GB. The onboard IDE controller supports Ultra DMA 33/66/100 mode and the
transfer rate up to 100MB/s. Further flexibility can be achieved by taking
advantage of the Communication and Network Riser (CNR) card option
that allows audio and modem configuration on a single
baseboard design. Besides, the MX4LS has an AC97 CODEC
chipset onboard, providing high performance and magic
surround stereo sound to let people enjoy working with it. Now,
let’s enjoy all features from AOpen MX4LS motherboard.

CPU
Supports Intel® Socket 478 Pentium®4 (Brookdale) 1.4GHz~2.4GHz+ with 400MHz Front Side Bus (FSB) designed for Socket
478 technology.
Chipset
With Intel®845GL (Brookdale) chipset, Intel delivers a discrete graphics solution with all the performance, innovative features
and proven reliability of the Intel®845GL chipset. With its highly scalable design, the new 845GL chipset offers an ideal,
multiplexed Intel DVO Port for Intel®Pentium®4 processor platforms. And the smart integration in the Intel 845GL chipset's I/O
Controller Hub (ICH4) features USB controllers supporting six USB2.0 ports. With support for AC’97 audio and the ability to
make the most of soft audio/modem technology, the 845GL chipset delivers an ideal solution for innovative new form factors.
Expansion Slots
Including three 32-bit/33MHz PCI, one CNR and one multiplexed Intel DVO Port. The PCI local bus throughput can be up to
132MB/s. The Communication & Nectworking Riser (CNR) slot provided from MX4LS support CNR interface for a Modem/Audio
card. The multiplexed Intel DVO Port specification provides a new level of video display sophistication and speed which
supports DVI/TV-Out add-on card. Of three PCI slots provided, all of them are master PCI slots with arbitration and decoding for
all integrated functions and LPC bus.

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 notice that some of the functions are
marked as “User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included
many amazing and powerful features, sometimes not every user is familiar with these powerful features. As a result of this we
define features that can be upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing
additional devices. As for functions that cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If
need be, you can contact our local distributors or resellers to purchase “Manufacture Upgrade Optional” components, and again
you are also welcome to visit our official website at www.aopen.com for detail information.

2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin1 & pin2.
5. Connect ATX power cable back to connector PWR2.
Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…
3. Troubleshooting…
