Soft BIOS CPU Speed and Multiplier Settings
Conventional motherboards might require the user to configure CPU speed, FSB (motherboard or system bus) speed, and clock multipliers through a series of jumpers or switches or through BIOS configuration screens. One danger to BIOS configuration is that the user might create a configuration that won't allow the system to boot and might require the CMOS configuration to be deleted to enable the user to try another option.
A number of different motherboards now offer BIOS-controlled configuration of CPU speeds, clock multipliers, FSB (motherboard/system bus) speeds, and CPU core voltage.
