Recently upgraded my Abit KR7A-133 mobo with an Athlon XP 2400+. It doesn't seem to be working out too well though. Problem 1: If it boots at all, it shows it to be running at 1500Mhz (100FSB x 15.0). When I manually change to the correct settings I get Problem 2. Problem 2: Often it just does not boot up at all. No POST......nothing. For reference, I've never had a problem with my XP 1900+. As far as I can tell, this should work. Same technology as my 1900+. I realize it won't automatically detect it, but I should be able to put in the settings manually (133 FSB x 15.0)and have it run no prob. Right? Maybe I've missed something. Any ideas? Thanks!
