E.2 FUNCTIONAL DESCRIPTION
The NVIDIA Quadro2 MXR Graphics Card provides high performance 2D and 3D display
imaging. The card's AGP design provides an economical approach to 3D processing by off-
loading 3D effects such as texturing, z-buffering and alpha blending to the system memory while
32 megabytes of on-board SDRAM stores the main display image.

The NVIDIA Quadro2 EX/MXR Graphics Cards include the following features:
♦ 32-MB SDRAM frame buffer using 128-bit 183-MHz access
♦ AGP 4X transfers with sideband addressing
♦ 2D drawing engine
♦ 3D rendering engine
♦ 350-MHz RAMDAC
♦ 32-bit Z/stencil buffer eliminates hidden screen portions for faster loading
♦ 32-bit color for increased image quality
♦ 30-fps full-screen DVD playback
♦ Dual-monitor support with a PCI graphics card
♦ DVI monitor support (Quadro MXR only)
The NVIDIA Quadro2 MXR provides, in addition to the RGB monitor connector, a digital video
interface (DVI) connector that can directly drive a DVI monitor or another RGB monitor through
an adapter.
