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 SUPER S2DM3/S2DME motherboard. The SUPER S2DM3/S2DME
supports dual Pentium®III/II Xeon 400-800 MHz processors. Please refer to
the support section of our web site (http://www.supermicro.com/
TechSupport.htm) for a complete listing of supported processors.
Manual Organization
Chapter 1 includes a checklist of what should be included in your mainboard
box, describes the features, specifications and performance of the SUPER
S2DM3/S2DME mainboard and provides detailed information about the
chipset.
Chapter 2 begins with instructions on handling static-sensitive devices. Read
this chapter when you want to install the processor and DIMM memory mod-
ules and when mounting the mainboard in the chassis. Also refer to this
chapter to connect the floppy and hard disk drives, SCSI drives, the IDE
interfaces, the parallel and serial ports and the twisted wires for the power
supply, the reset button, the keylock/power LED, the speaker and the key-
board.
If you encounter any problems, see Chapter 3, which describes troubleshoot-
ing procedures for the video, the memory and the setup configuration stored
in CMOS. For quick reference, a general FAQ [Frequently Asked Questions]
section is provided. Instructions are also included for contacting technical
support. In addition, you can visit our web site at www.supermicro.com/
techsupport.htm for more detailed information.
Chapter 4 includes an introduction to BIOS and provides detailed information
on running the CMOS Setup utility.
Appendix A offers information on BIOS error beep codes and messages.
Appendix B provides post diagnostic error messages.
