iv SPARCengine Ultra AX i OEM Technical Manual • May 1999
Preface
The SPARCengine Ultra AXiproduct is a highly integrated, high performance
motherboard designed for the use of OEMs who want to develop products that have
UltraSPARC performance in a PC-ATX environment.
The SPARCengine Ultra AXi OEM Technical Manual describes the functions of the
SPARCengine Ultra AXimotherboard, its controls, indicators, connectors and
pinouts, boot sequence, diagnostics, troubleshooting, installation and removal
procedures, and its specifications. It also provides some of the critical mechanical
drawings for the motherboard and CPU module.
Who Should Use This Book
The SPARCengine Ultra AXi OEM Technical Manual is written for computer
hardware engineers, system programmers, computer technicians and others
involved in the integration of the Ultra AXimotherboard. References are provided
for further details.
How This Book Is Organized
The SPARCengine Ultra AXi OEM Technical Manual is organized as follows:
Chapter 1, “Introduction” explains the capabilities and major features of the Ultra
AXimotherboard.
Chapter 2, “Specification Summary” provides a summary of specifications of the
Ultra AXimotherboard.

v
Chapter 3, “Functional Description” provides a short description of the function of
each component on the Ultra AXimotherboard.
Chapter 4, “Sequence of Events at Power Up” details the sequence of events that
occur at Power Up and discusses interaction with OBP and Solaris where applicable.
Appendix A, “Jumpers, Headers, Connectors, and Adapters” describes the jumper
settings, header pinouts, connector pinouts, and adapters on the Ultra AXi
motherboard.
Appendix B, “Mechanical Drawings” provides the drawings for the I/O panel,
CPU module, Ultra AXimotherboard, Creator Graphics module and a thermal map
of the motherboard.
Appendix C, “Assembly, Installation and Initial Start Up Procedures” describes
how to assemble and install a motherboard in a typical ATX-type enclosure and
describes how to install the required software and initially start the system.
Appendix D, “OpenBoot Firmware” provides information on the OpenBoot
Firmware used in the Ultra AXisystem.
Appendix E, “System Software Solaris 2.6 Operating Environment” provides
information on the Solaris 2.6 Software used in the Ultra AXisystem.
Appendix F, “System Software SunVTS Validation Test Suite” provides
information on the SunVTS suitable for the Ultra AXisystem based on SunVTS 2.1
Ultra AXiversion.
