INTEGRATED GRAPHICS SUBSYSTEM

6.Chapter 6 Intregrated Graphics Subsystem

6.1INTRODUCTION

This chapter describes graphics subsystem that is integrated into the IGP component on the system board. This graphics subsystem employs the use of system memory to provide efficient, economical 2D and 3D performance.

Upgrading these systems is accomplished by installing a separate AGP graphics card in the AGP slot. The system will detect an AGP graphics controller card during the boot sequence and disable the integrated graphics controller of IGP.

This chapter covers the following subjects:

♦	Functional description (6.2)	page 6-2
♦	Display Modes (6.3)	page 6-5
♦	Programming (6.4)	page 6-6
♦ Upgrading IGP-based graphics (6.5)		page 6-6
♦ VGA Monitor connector (6.6)		page 6-7
