Hey Bockko, I had all kinds of problems trying to get my new 2.4 to run on 98. You can do it, but it will be a pain. I had all kinds of driver problems, 98 just doesn't know what to do with the new technology. Finally broke down and picked me up XP.
Never did get things to run %100 with 98. Especially had problems running AH, my frame rate sucked, I had sound problems and it took 3 hours to get my USB2 stuff going. After XP, AH ran as smooth as a baby's bottom!
