Product Description

The S3 86C260 ViRGE^®/MX 2D/3D accelerator with DuoView architecture provides the combination of features, performance, and power conservation desired for the mobile market. ViRGE/MX is the second in a series of highly-integrated flat-panel controller products to be offered by S3 with the goal of providing better-than-desktop features and performance to the notebook computers. It utilizes the award-winning ViRGE 2D/3D engine integrated with a 64-bit synchronous or EDO memory interface, a 24-bit high-performance 135 MHz RAMDAC, a flat panel interface capable of controlling the latest STN and TFT panels, S3's Scenic Highway^TM multimedia interface and Streams Processor^TM video acceleration technology, and fully integrated, flicker-filtered NTSC/PAL output. These elements are then designed to function with S3's unique DuoView architecture, allowing mobile users to take optimal advantage of their notebook's multiple display capability. Comprehensive, flexible hooks are provided to simplify graphics subsystem power management, while dynamic power control of internal functional modules ensure that power drain is minimized during active operation.

Full Software Support

Video BIOS and drivers supporting the major operating systems and APIs [Windows( 95, Windows 3.11, Windows NT(, OS/2( 3.0 (Warp^TM), Direct 3D^TM, BRender^TM, RenderWare^TM, OpenGL^TM] are provided for OEM customers. The ViRGE/MX supports the S3d^TM Toolkit and is compatible with existing S3d logo games supporting 3D acceleration on ViRGE desktop accelerators. ISV and marketing programs funded by S3 ensure abundant title support is available that utilizes the unique and compelling hardware features provided in S3 graphics accelerator products.
