Also, text mode scrolling should be faster. Some bioses might set the memory type registers correctly. Some do not (mine doesn't.) There was a bug in my initial version, in that the memory type was not being set correctly for the video mem (it was being set to 0, instead of 1 (write combining).) The ISA memory hole video mem was being set correctly though. I don't have time to look at it right now. Sorry... Lars is supporting it though :-). -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
