A method for preventing a BIOS from getting viruses, wherein a changeable memory for storing BIOS codes is divided into two areas, one is a primary actuating area and other is a duplicating area. Initially these two areas store identical BIOS. The method comprises the steps of actuating from the primary actuating area and determining whether the step of actuating exists; performing the process to a testing point, and comparing the check sums of the primary actuating area and the duplicating area; through the comparison, performing the starting up process from the primary actuating area and duplicating area and copying the data of the primary actuating area and duplicating area to one another to maintain one area having a complete BIOS in order to prevent the BIOS from being destroyed by virus, or by abnormal modification, so that the system operates normally.

Method for preventing a BIOS to get viruses

The invention provides a method of automatically overclocking CPUs for a computer system by using a frequency generator with functions of tuning frequency and monitoring, and applying a numeric method to get the frequency for booting a computer system. When a computer system is powered on and enters the overclocking process, the built-in parameters storing booting settings are loaded and backed up to be referenced in the next trial of booting. The frequency of overclocking is calculated by a numeric method according to the highest frequency generated by the frequency generator and the frequency of front side bus of the system. The built-in parameters are then stored to boot up a computer system at next time. Once the configuration of the computer system is changed, the values of parameters are invalid and need to be recalculated by entering the overclocking process. Using this automatic method, overclocking can be done in a shorter time than overclocking manually.
