Preface Preface About This Manual This manual is written for system integrators, PC technicians and knowledgeable PC users. It provides information for the installation and use of the X7DAL-E motherboard. The X7DAL-E supports dual Intel Xeon dual core/quad core processors (w/771 LGA) with a front side bus speed of 667 MHz/1.066 GHz/1.333 GHz. With dual 64-bit Xeon dual core/quad core processors built in, the X7DAL-E substantially enhances the performance of motherboards based on the Intel dual core/quad core NetBurst microarchitecture while remaining compatible with the IA-32 software.

The features include Virtualization Technology, Thermal Monitor 1/2 (TM1/TM2), Enhanced Intel SpeedStep technology, Advanced Dynamic Execution, Advanced Transfer Cache, Streaming SIMD Extensions 3 (SSE3) and Extended Memory 64 Technology (EM64T). These features allow the motherboard to operate at a higher speed with better power management in a safer thermal environment than a traditional motherboard. The X7DAL-E is ideal for high performance dual processor (DP) workstations. Please refer to the moth- erboard speciﬁ cations pages on our web site (http://www.supermicro.com/products/ motherboard/) for updates on supported processors. This product is intended to be professionally installed.

Manual Organization Chapter 1 describes the features, speciﬁ cations and performance of the mother- board and provides detailed information about the chipset. Chapter 2 provides hardware installation instructions. Read this chapter when installing the processor, memory modules and other hardware components into troubleshooting procedures for the video, the memory and the system setup stored the system. If you encounter any problems, see Chapter 3 , which describes in CMOS. Chapter 4 includes an introduction to BIOS and provides detailed information on running the CMOS Setup utility. Appendix A, provides BIOS Error Beep Codes.

Appendix B and Appendix C list Windows OS and Other Software Installation Instructions.
