I just changed CPUs from 333/66 to 400/100 and I'm confused about how to set the jumper switch . The manual shows 266/400 set with 4 multiplyerb but if I set it for 4 then boot screen only shows 266. I have it set on 6 multiplyer and boot screen shows 400 when I boot. Also BIOS says its using 100 MHz FSB. Does anyone know what the switches should be?
