Yeah, fixed frequency monitors vary that much. And getting just one of the timing numbers off by a few counts does things like pushing column 1 off the screen so you can't read any of the lines in the boot display, so you can't even change CMOS settings or see what you're doing when you type commands for a video board configuration utility. It's happened to me. The only sure way to future-proof it, and lick the chicken-and-egg deadlock once and for all, is to provide a way to set the _exact_ modeline numbers for _any_ modeline, without first having _any_ kind of working display. That's what the SPI modeline tool with the 120 DIP switches does. Anything else is half-measures and won't get the job done. Either we support fixed-frequency displays or we don't. Moving arbitrary mode configuration to an external tool takes the whole cost burden off the OGC1, and requires only a very minimal amount of logic in the ASIC to read in the switch states. The rest can be done in BIOS code. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
