FastEd, if your PIII does work, and you want to sell your 533a let me know, my girlfriend wants to upgrade her BM6.
Dan808, No powerleap adapter is needed for the CII 566 on the BM6. If your having problems booting up, check your AGP divider, and make sure you have excellent cooling and thermal paste. I remember when I first got my CII I tried to run it with a heatsink only, no fan, just to see how it would overclock. 75mhz bus was the only speed I could use. And this was on on a system that was at room temp. anything else I tried was an instant lock-up. And this was with the cpu that is in my sig rig. I'm using a Gorb with silver paste.
