Thank you for choosing AOpen MX4LR motherboard. The MX4LR is Intel Socket 478 motherboard (M/B) based on the ATX form factor featuring the Intel® 845GL(Brookdale) chipset. As high performance chipset built in the M/B, the MX4LR motherboard can support Intel Socket 478 Pentium 4 (Brookdale) and 400 MHz Front Side Bus (FSB) clock. According to different customer's requirements, the Intel 845GL chipset memory interface supports DDR266 SDRAM devices with densities of 64, 128, 256, 512Mb DDR 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, modem, and/or LAN configuration on a single baseboard design. Besides, the MX4LR 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 MX4LR motherboard.

Online Manual
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.
