ATI mach64-GX (ISA) Graphics Option

This owner's guide provides comprehensive instructions for installing and configuring the ATI mach64-GX (ISA) Graphics Option on Digital AlphaServer 2000/2100 and 400/1000 systems. The ATI mach64-GX is a 16-bit ISA bus graphics accelerator module featuring 2 MB of DRAM video memory, supporting up to 16.7 million colors, refresh rates up to 75 Hz, and display resolutions up to 1280 x 1024.

The installation process is detailed for three operating systems: Digital UNIX, OpenVMS Alpha, and Windows NT. It covers:

1. Hardware Installation: Step-by-step instructions for safely installing the graphics circuit card into an available ISA/EISA expansion slot, including precautions against static electricity.
2. Firmware Configuration: Guidance on configuring the system firmware (using iconfig for ISA bus systems or the ECU utility for EISA bus systems) to recognize the mach64-GX option.
3. Operating System Driver Installation and Configuration:
   • Digital UNIX (V3.2c+): Describes installing the necessary display drivers (either fresh installation or updating an existing system) and changing display characteristics, including supported resolutions (e.g., 1280 x 1024 at 72 Hz).
   • OpenVMS Alpha (V6.2+): Details the installation of drivers from a supplied update kit using VMSINSTAL, and how to modify display settings and resolutions.
   • Windows NT (V3.51+): Explains installing the graphics update kit via the Control Panel's Display settings, or during a custom Windows NT installation, along with procedures for changing display characteristics and supported resolutions.

The guide emphasizes checking monitor specifications for compatibility and highlights minimum firmware requirements for EISA systems.
