If you know what you're doing and would like to overclock the chip a tad, set these jumpers a little differently. If your manual lists settings by CPU, just do what it says. You can sometimes infer from the manual which switches control voltage, multiplier, etc. Also, watch for chips that use different multiplier settings than they actually use. For example, many 233MHz chips use a 3.5x multiplier, but since some boards don't offer this option, they interpret the 1.5x multiplier to be 3.5x.
Some boards make use of a jumper to set the cache size and type.
Set this now, if need be. If you have on-board cache, which most do, you won't need to bother. Older boards often had a jumper setting for telling the system how much memory it had. If your has it, set this now. Most Pentium-class boards don't have this jumper.
