Digital PowerStorm 4D51T GFX Graphics Option

This document is the Installation Guide for the DIGITAL PowerStorm 4D51T GFX Graphics Option, designed for Intel systems running Windows NT, published in April 1998. It provides comprehensive information for installing and using the graphics option.

The PowerStorm 4D51T GFX graphics option consists of a PowerStorm 4D51T graphics accelerator module and a DSP-based GFX geometry accelerator module, connected by a 60-pin Vertex data bus ribbon cable. This option generates high-resolution, 3D color graphics for applications such as CAD, molecular modeling, scientific visualization, and animation. Key features include performance up to 1.2 million triangles per second (3D, Z-buffered, Gouraud shaded), support for Windows NT graphics (GDI and OpenGL), resolutions up to 1280 x 1024, various graphics features (e.g., Gouraud shading, texture processing, alpha blending), 16 MB SDRAM frame buffer memory, 10-bit gamma correction, and hardware acceleration for graphics transformations and calculations. The package includes the two modules, ribbon cable, installation guides, and an antistatic wriststrap. Compatible software versions are Windows NT 4.0 SP3 and Graphics Support Services Software 4.6.

The installation procedure involves preparing the system by powering it off and opening the chassis, then physically installing the PowerStorm 4D51T and GFX modules into adjacent PCI slots on the same bus, connecting them with the Vertex data bus ribbon cable, and reassembling the system. Critical precautions include using an antistatic wriststrap and ensuring adequate airflow for the modules. The guide also details steps to confirm proper installation and provides troubleshooting advice for common display issues.

Appendices cover monitor resolutions supported for Windows NT systems, physical and environmental specifications (weight, dimensions, temperature, power consumption), pinout details for video output, VGA input, and stereo sync output ports, and available cable options. A final appendix lists Field Replaceable Units (FRUs) and their order numbers for service purposes.
