This is something that will have to be built into the video controller. Perhaps opcode 4 should be a set sync mode operation with the bottom eight bits being the sync mode bits: 7: reserved 6: reserved 5: reserved 4: reserved 3: hsync polarity (1 - positive, 0 - negative) 2: vsync polarity (1 - positive, 0 - negative) 1: composite sync 0: sync on green This way, the setting can easily be taken from the X modeline and compiled into the video controller program. Very likely that this opcode would only occur once per program, however it might be a good solution.

the type of sync the monitor needs (H&V, Composite, on Green).
Sync on green could be an issue. We need to have a look at the design and see what it would require. The others are no problem. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com) _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
