G.2 FUNCTIONAL DESCRIPTION
The Diamond Fire AGP Graphics Card is based on the NVIDIA RIVA 128 graphics controller.
The AGP design provides an economical approach to 3D processing by off-loading 3D effects
such as texturing, z-buffering and alpha blending while the on-board SGRAM stores the main
display image. This card includes four megabytes of 100-MHz SGRAM memory. The graphics
BIOS code is contained on-board in flash ROM and is easily upgradeable.
