A Central Processing Unit (CPU) frequency adjusting system has a multi-level architecture including an application level, a driver level, a hardware abstraction level, and a hardware platform. The application level includes a user interface () for generating a command signal to adjust a CPU frequency according to an input from a user, and displaying an adjusted CPU frequency. The hardware abstraction level includes a frequency adjusting module () for adjusting a current CPU frequency in a flash memory () with the new CPU frequency input by the user; and a data accessing module () for storing the adjusted CPU frequency in the flash memory, and reading the adjusted CPU frequency from the flash memory in order to display the adjusted CPU frequency on the user interface. The CPU frequency adjusting system can reduce the complexity of the hardware abstraction level, and is compatible with different types of BIOSs.

CPU frequency adjusting system and method

A system for updating a sign-on logo image file in a computer includes: a storage medium () for storing image files; application software () for loading a selected image file, converting the selected image file into a designated format image file, and compressing the designated format image file into a corresponding sign-on logo image file; a dynamic link library (DLL) () for receiving the sign-on logo image file from the application software; a basic input/output system (BIOS) () for receiving the sign-on logo image file from the DLL through a driver model () which connects the DLL with the BIOS, determining whether the sign-on logo image file is valid according a size of the sign-on logo image file, and updating the sign-on logo image file in the computer if the sign-on logo image file is valid; and a read only memory () for storing the sign-on logo image file. A related method is also disclosed.
