Thank you for choosing AOpen AX4R Plus motherboard. The AX4R Plus is Intel®Socket 478 motherboard (M/B) based on the ATX form
factor featuring the Intel® E7205 chipset. As high performance chipset built in the M/B, the AX4R Plus motherboard can support Intel®
Socket 478 Pentium®4 and 400/533 MHz Front Side Bus (FSB) clock. According to different customer’s requirements, the Intel E7205
chipset memory interface supports DDR200/266 RAM devices with densities of 64, 128, 256, 512Mb DDR RAM DIMM modules and the
maximum memory size can be up to 4 GB. The onboard IDE controller supports Ultra DMA 33/66/100 mode and the transfer rate up to
100MB/s. With a Silicon Image Serial ATA (Sili3112ACT144) controller onboard, it aims to provide you an even faster transfer rate of 150
Mbytes/second. Further flexibility can be achieved by taking advantage of the Communication and Network Riser (CNR) card option that
allows audio, modem configuration on a single baseboard design. More than that,
on the strength of RealTek RTL8100BL controller on board, which is a
highly integrated Platform LAN Connect device, it provides 10/100M
bps Ethernet for office and home use. Besides, the AX4R Plus 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 AX4R Plus motherboard.

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
“Manufacturer Upgrade Optional”, and some are called “User 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 “Manufacturer Upgrade Optional” for you to choose. Some optional functions that can be upgraded by
users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them
“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade
Optional” components, and again you can visit AOpen official web site: www.aopen.com for more detail information.
