At the moment Ive put a new stick of 512Mb pc 133 in slot 1 of my motherboard. Originally there was a stick of 256Mb in slot 1 but I have put that into slot 2. But when I boot up it only picks up the 512Mb stick in slot 1. This means that i would presume that slot 2 is disabled, how can I enable it? I have looked in the bios and in the motherboard manual and I cannot find anything on it.
