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 Quad-Core and Dual-Core processors with a front side bus speed of 1.333 GHz/1.066 GHz/667 MHz. With two 64-bit Quad-Core and Dual-Core processors built-in, the X7DAL-E+ offers substantial functionality enhancements to the mother- boards based on the Intel Core Microarchitecture cores while remaining compatible with the IA-32 software.

The features include Intel Hyper-Threading Technology, Virtualization Technology, Hyper Pipelined Technology, Execution Trace Cache, 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 much higher speeds with better power management in much safer thermal environments than the traditional motherboards. The X7DAL-E+ is ideal for high performance quad-processor or dual-processor (DP) workstation and enterprise server environments.

Please refer to our web site (http://www.super- micro.com/products/) for updates on supported processors. This product is intended to be installed and serviced by professional technicians. Manual Organization Chapter 1 describes the features, speciﬁ cations and performance of the mainboard and provides detailed information about the chipset. Chapter 2 provides hardware installation instructions. Read this chapter when in- stalling the processor, memory modules and other hardware components into the system. If you encounter any problems, see Chapter 3 , which describes trouble- shooting procedures for video, memory and system setup stored in the CMOS.

Chapter 4 includes an introduction to BIOS and provides detailed information on running the CMOS Setup utility. Appendix A lists BIOS Error Beep Codes. Appendix B and Appendix C provide the Windows OS and other software instal- lation instructions.
