Intel740™ Graphics Accelerator Design Guide 1-1
Introduction
Introduction
1
This document provides a complete package of design information for the Intel740™ Graphics
Accelerator. There are two design discussed:
•
ATX Addin Card Design (Chapter 2 provides design considerations, layout and routing
guidelines, and schematic diagrams)
•
Motherboard Design (Chapter 3 provides design considerations, layout and routing guidelines,
and schematic diagrams)
The purpose of the reference design is to provide a comprehensive design encompassing every
Intel740™ graphics accelerator interface. The designer of another board may then modify this
design as needed since the basic hook-up will remain the same.

1.1 About This Design Guide
This design guide is intended for hardware designers who are experienced with PC architectures
and board design. The design guide assumes that the designer has a working knowledge of the
vocabulary and practices of PC hardware design.
•
This chapter introduces the designer to the organization and purpose of this design guide and
provides a list of references and related documents.
•
Chapter 2, "Addin Card Design"—This chapter provides a detailed set of Intel740™ graphics
accelerator design information for ATX and NLX graphics cards. The basis of the design
information is a reference ATX card design. Schematics for the reference design are provided
at the end of the chapter.
•
Chapter 3, "3 Device AGP Motherboard Design"—This chapter provides design guidelines for
developing a motherboard based on the Pentium II
®
processor, Intel
®
440BX AGPset, and the
Intel740™ graphics accelerator. The main focus of this chapter is the guidelines for
developing a 3-point AGP solution with the Intel740 graphics accelerator and provides a
detailed set of design information for a 3-point AGP reference design (DS1P/440BX/I740).
Schematics for the reference design are provided at the end of the chapter.
•
Chapter 4, "Thermal Considerations"—This chapter introduces the topic of thermal
considerations. See Application Note 653 in Appendix A for a comprehensive description of
thermal considerations.
•
Chapter 5, "Mechanical Information"— This chapter provides mechanical information on Fan/
Heatsink, VMI Header Placement, Video Connector, brackets, and NLX considerations.
•
Chapter 6, "Third Party Vendor Information"— This section includes information regarding
various third-party vendors who provide products to support the Intel 440BX AGPset and the
Intel740 graphics accelerator.
•
Appendix A, "Application Notes"—This appendix contains Application Note 653, Thermal
Design Considerations. The application note provides a comprehensive guide to thermal
design
•
Appendix B, "Reference Information"—This appendix provides reference information for
designing with the Intel740 graphics accelerator. The appendix contains information on
