- I had heard that source code to some of the presentation drivers was
- available. I have a Definicon CAD-RACE card based on the Tseng 4000
- that the SP doesn't recognize. It's capable of 1024x768x256, and has
- an Edsun CEG DAC (does anti-aliasing). The manufacturer isn't
- supplying OS/2 support, so I'd just like to modify an existing driver
- to do the job.
-
- Am I correct in assuming that the main device-specific functions are
- mode-switching, VRAM access (ie. mapping pixel coordinates to VRAM
- addresses), and state-saving for DOS sessions?
-
- How do I get a copy of the Tseng driver source? I'll sign a
- non-disclosure if appropriate.
