Chapter 2. System-Board Features
Video Subsystem
The video subsystem on the system board includes the Integrated AGP Cirrus GD5465 3-D SVGA (super
video graphics array) controller. The system board supports up to two RDRAM memory modules. Each
module contains 2 MB of RDRAM memory.
Integrated AGP Cirrus GD5465 3-D SVGA (super video graphics array)
The Integrated AGP Cirrus GD5465 3-D SVGA (super video graphics array) supports all video graphics
array (VGA) modes and is compliant with super video graphics array (SVGA) modes, Video Electronics
Standards Association (VESA) 1.2. Some enhanced features are:
Plug and Play support
533 MHz RAMBUS DRAM support
Advanced Power Management support
Color space conversion
Hardware scaling
AGP bus and is AGP 1.0 compliant. The CL-GD5465 video subsystem supports the VESA Display Data
Channel (DDC) standard 1.1 and uses DDC1 and DDC2B to determine optimal values during automatic
monitor detection.
For information on resource assignments, see Appendix B, “System Address Maps” on page 41 and
Appendix C, “IRQ and DMA Channel Assignments” on page 45.
The video subsystem provides a 15-pin monitor connector on the system board; For information on
connector pin assignments, see “Monitor Connector” on page 32.
Video Memory
The video memory interface is controlled by the GD5465 graphics controller.
The amount of RAMBUS RDRAM shipped with the video subsystem is 2MB.
The video memory module used is a 2MBX9 533MHz RDRAM.
