Features of the NVidia 4x AGP adapter
The NVidia 4x AGP adapter is a 2D/3D video adapter with 16 MB SDRAM that
includes:
• AGP 4x interface
• 128-bit TwiN-Texel architecture (TNT2 M64)
• 16 MB SDRAM frame buffer with 64-bit interface
• 64 MB frame buffer supporting SuperScene, full-scene, multi sampled anti-
aliasing
• 250 MHz, internal RAMDAC that supports up to 85 Hz refresh rate at 1280 x 1024
resolution
• High-resolution support up to 1600 x 1200
• High-performance 128-bit 2D/graphical user interface (GUI)/DirectDraw
acceleration
• Fast 32-bit VGA/Super VGA (SVGA) support
• High performance implementation of Direct 3D and OpenGL standards
• Video acceleration for DirectShow, MPEG-1, MPEG-2, and Indeo
• Multiple monitor support
• Advanced power-management support
• Complete Plug and Play support
• Compliance with the following standards:
— AGP 2.0
— VESA VBE V2.0/3.0
— DDC2B
Monitor support
The video subsystem provides a 15-pin analog monitor connector for the integrated
video subsystem on the system board in addition to a 15-pin analog connector on a
graphics adapter (if present). When an AGP graphics adapter is installed in the
computer, the 15-pin monitor connector for the integrated video subsystem will go
unused. For multiple monitor support, either the integrated video subsystem or AGP
adapter must be used in conjunction with a PCI graphics adapter. For information on
connector pin assignments, see “Monitor connector” on page 29.
Audio subsystem
The NetVista computer comes with an integrated audio controller. These models are
capable of playing and recording sounds and support SoundBlaster, Adlib, and
Microsoft Windows Sound System applications.
The device drivers are on the hard disk and are also available on the Product
Recovery Program on the hidden partition of the hard drive if the computer comes
with preinstalled software.
If you connect an optional device to the audio connectors, follow the instructions
provided by the manufacturer. (Note that device drivers might be required. If
necessary, contact the manufacturer for information on these device drivers.)
