Hi. I'm building a system with an EPoX 8K7A and a 1.2GHz 266FSB Athlon with 512MB PC2100 DDR RAM. My questions are about putting these all together and getting the jumper setting correctly. If you can answer any of these question, I'd really appreciate it because it'd help me out a lot. Here goes... 
1. SW2 is the CPU Ratio Selection, set to AUTO by default. But IF that doesn't work for some reason, is this analagous to what I've known as the Clock Multiplier? Do I just find that 133MHz x 9 = approx. 1.2GHz and hard set it that way? Or is the CPU Ratio Selection something else?
2. JCLK1 is CPU Clock Select, set to 100MHz be default. The 266MHz FSB is supposed to be achieved onboard by 133MHz x 2. I heard a rumor that you have to install the chip with the 100MHz clock select, let it boot once, then shut down and change the setting to 133MHz. Is this true, or can (should) I just set it to 133MHz before the first boot?
3. JP2 is CPU VCore Adjust. I'm assuming since there's no explicit CPU voltage core setting that it can automatically detect the chips voltage. However, if I'm wrong, what should I adjust it to? The default is to leave it alone (+0V).
4. JP3 is DDR Adjust (2.5V). The default in this case is +0.1V, but the RAM I bought from Crucial says it's 2.5V on the dot. Should I move it back to +0.0V, or is it set this way by default for some reason?
5. Crucial says the timing on the RAM is CL=2.5 (whatever that means). The motherboard requires PC2100 RAM with 2-2-2 timing. Are these the same thing? If not, am I in trouble?
Thanks SO much for all your help! I really appreciate it.
