- I picked up the Preliminary Release of Windows NT, and Im
- impressed enough to put together a system. In the longer
- term future, if Microsoft or SGI really does make OpenGL
- available, Id like to get something like an i860 graphics
- board capable of 24-bit color. The problem is the bus. Im
- pretty sure the old SGI 3000 series boxes just used VME to
- talk to the graphics subsystem, and the processors were dead
- slow, yet they had great performance. Given that most of
- the rendering would be on the board I see no reason why EISA
- wouldnt be able to handle it.
-
- So now that its "predict the future" time, I need some
- information on the past. How popular has EISA become? Ive
- heard that 50% of the cards that are available are SCSI
- controllers, which doesnt speak for diversity. Id rather not
- wait till VESA gets standardized, chips come out and they
- start to come down in price, yet Id like to put together a
- system that I can expand over time (the box Im looking at has
- a replacable processor module so I could put a P5 in it.
- The graphics adapter is my only other concern.)
-
- Also, are there any EISA graphics adapters that support the
- display memory as a linearly addressable region? Its my
- understanding that VGA breaks the display up into non-rectagular
- regions which make any drawing operation a painful sequence
- of bank switching operations.
-
- General opinions about EISA, current 24-bit solutions, etc...
- are appreciated. -Steve
