PROBLEM TO BE SOLVED: To provide an information processor, a frequency control method for a CPU, and a program, capable of changeover-controlling a frequency of the CPU in multi-stages without preparing a BIOS according to the kind of each the CPU to a plurality of kinds of CPUs each having a different operating frequency or without accompanying rewriting, a change or the like of the BIOS. SOLUTION: The BIOS stored in a BIOS-ROM 12 has: a processing function updating a table (TBL) wherein a voltage value and the frequency of the CPU 11 supplied from an FDD 15 are defined into a flash memory 13; and a processing function setting the voltage value and the frequency based on the table (TBL) stored in the flash memory 13 to the CPU 11, and controlling the frequency of the CPU 11. Thereby, by only changing the table wherein the voltage value and the frequency of the CPU supplied from an external storage device, desired frequencies can be set to all the CPUs each having the different operating frequency.
