I thought I read somewhere on AMDMB forums about not installing the entire package because part of it could cause problems in your system. I already installed one KT3ultra2 board overa onth ago and it went smooth, but I can rem if I installed the complete 4in1 package or if I followed the install advice I got last time and just installed the INF file and not the miniport, AGP, or or IDE modules. This second system is giving me transfer problems now for a week with random boots etc, so I am trying to isolate and mimic my first system to see what I am doing wrong. So any other KT3Ultra2 owners out there on WIN98SE full install? what worked for you? of if you installed XPpro, did yoiu install all 4 modules or just part? I have winxpro full version here, jsut didnt want to start on a whole new OS that I know nothin about till I find the problem under win98se, Like I said an almost identical comp is runnin fine right next to it so the installed components drivers all look same except I dont know how to look and see what part of the 4in1 I installed last time?
