After this, set the multiplier. This will depend on the CPU you are using. For example, let's say you are installing a Pentium II-266. You set a bus speed of 66MHz. In order to run the processor at its intended speed of 266MHz, you must set a 4.0x multiplier.
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. Likewise, some boards give you the ability to use either AT or ATX power supplies. Depending on which type you will be using, you may need to set a jumper to tell the board what type of power to use. You can set the system bus speed at 100MHz and then set the memory to run at 66MHz or 75MHz.
