FSB SEL should be set to the processors default FSB. E.g. AXP 3200+ should be set to 200. AXP 2500+ set to 166 etc.	FID 0 ~ FID 4 allows you to change the multiplier of the board. No Jumpers are provided though in the package.

CPU Host frequency can be set to AUTO or Manual. When set to Manual, you can adjust it from 100 ~ 248 at 1MHz stepping. DRAM Frequency can be set to run at 200 for Sync (since i am using AXP3200+) or at 166,133,100. Flexibility Option is disabled as this will reduce the performance for max compatibility with different ram modules.	Under the chipset configuration, we set DRAM manually. ECLK you see here is the Graphics core engine clk. There are available options of 133,166,200. We tried 200 but it hung. 166 is OK. DRAM CAS Latency is set to 2

We also set tRAS to 6, 5 is too aggressive. tRCD and tRP are set to 2. Thus we have CAS 2, 6-2-2.	VCCM voltage to 2.73V which is default. You can select 2.58v and 2.62v.

Over Vcore voltage can be adjusted up to +3% or +6%.
