Abstract: An exemplary method for BIOS setup includes the steps of: setting selectable options of device configurations according to parameter ranges of device configurations of the BIOS, each selectable option corresponding to a selection indicator, each selection indicator corresponding to a type of color and an alarm sound; modifying working condition parameters of the device configurations; determining whether the new configuration values are dangerous values; determining the selection indicator according to corresponding selectable options of device configurations if any new configuration value is a dangerous value; and displaying the device configuration with corresponding color, and alarming with the corresponding alarm sound. A related system for BIOS setup is also disclosed.

Abstract: A method for reconfiguring an RTC time of a computer is disclosed. The method includes the steps of: storing an initial real time clock (RTC) time when the computer is powered on; calculating a first elapsed time tracked from the initial RTC time and a second elapsed time tracked from the initial RTC time; reading an RTC time of the computer after a time span of the first elapsed time; detecting whether the RTC time equals the sum of the initial RTC time and the first elapsed time; and adjusting a current RTC time of the computer after a time span of the second elapsed time to the sum of the initial RTC time and the second elapsed time, if the RTC time doesn't equal to the sum of the initial RTC time and the first elapsed time. A related system is also disclosed.

Abstract: A method for overclocking a CPU is provided. The method includes the steps of: receiving a desired frequency; reading a current working frequency of the CPU; determining whether the current working frequency equals the desired frequency; determining whether the current working frequency is less than the desired frequency if the current working frequency does not equal the desired frequency; increasing the current working frequency by 1 MHz, if the current working frequency is less than the desired frequency; decreasing the current working frequency by 1 MHz, if the current working frequency is larger than the desired frequency. A related system is also disclosed.
