Yes, up to a point. I developed a VGA BIOS once that hung on an interrupt and looked for changes in the text display, updating graphically anything that changed. It worked well until an OS took over and switched to protected mode. I was never able to find a way to solve this problem for either Linux or Solaris x86. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
