| 2. If not, how does the OS know that the GX Accelerator is installed?
| 3. Is the performance I am seeing under Sunview reflecting the operation

I received a number of responses. The answers to my questions are:

1. This patch tape is not appropriate for the Sparcstation.

2. The OS knows about the cgsix because of a line in the kernal
    configuration file. This line is:
  device-driver cgsix # 8 bit accelerated color frame buffer

3. Sunview, and any other application that uses the pixrect library,
    will automatically use the cgsix accelerator.

Thanks to all who responded.
