Abstract: A basic input output system (BIOS) setting method is applicable to a BIOS setting procedure of a data processing unit having a display unit and an input unit. After the data processing unit is turned on and a power on self test (POST) procedure of the BIOS is being executed, messages of a first function key and a second function key are displayed on the display unit. If the first function key is pressed, a first BIOS setting mode is entered. After the first BIOS setting mode is entered, whether any setting contents of the first BIOS setting mode are revised and saved in the data processing unit is determined, and the corresponding POST is executed based on the revised setting contents of the first BIOS setting mode, or the first BIOS setting mode is skipped and the continuing POST procedure continues to be executed.

Abstract: A current overload detecting system and method applicable in a data processing device connected with a plurality of electronic devices is disclosed, each of the electronic devices having a USB interface. The data processing device has a plurality of USB ports corresponding to and connected with the USB interfaces, a plurality of USB control units for controlling the operations of the USB ports, and a basic input/output system (BIOS) for executing a POST process. The current overload detecting system includes a signal-detecting unit for detecting if the USB control unit of the data processing device is outputting an over-current when the BIOS of the data processing device is executing the POST process, outputting a control signal if the USB control unit is detected to be outputting the over-current signal; and a display unit for receiving the control signal and displaying corresponding messages according to the control signal.

Abstract: A message displaying system and method is applicable to an electronic device having a BIOS and a display unit that executes a POST process. The message displaying method includes establishing a message table according to a plurality of message codes output by the BIOS when the electronic device is executing the POST process and a plurality of message code messages corresponding to the message codes, reading message codes output by the BIOS when the electronic device is executing the POST process, reading one of the message code messages stored in the message table and corresponding to the read message code, and displaying the read message code and its corresponding message code message on the display unit of the electronic device. Thereby, a user of the electronic device can know the status of every stage of the POST process along with debugging information.

Abstract: A battery power detecting system is disclosed applicable to an electronic device having a volatile random access memory (VRAM) for detecting the battery power of a backup battery of the volatile random access memory. The battery power detecting system includes a detection module for detecting the battery power of the backup battery and for generating a detection signal; a reception module for receiving the detection signal; and a determination module for reading a state value of the detection signal received by the reception module, determining the battery power of the backup battery according to the state value, and generating alarm messages to notify a user that the backup battery is lacking in battery power when the backup battery is determined to be have insufficient battery power, so as to prevent data stored in the VRAM from being lost due to the lack of the battery power of the backup battery.

Abstract: A system and method for avoiding power shortage due to accidentally pressing a power control switch during a BIOS update is provided. When a power control switch is turned on, a control chip module is actuated to send a preset signal to a control element module and a control signal to a power circuit module. Thereafter, the power circuit module sends an activating signal to the control element module. The control element module then electrically processes the activating signal from and the preset signal to generate an electrical signal for activating a power supply. During BIOS update, a BIOS update module continuously sends a GPIO control signal to the control chip module to replace the preset signal for maintaining activated power supply during the BIOS update, and sends a GPIO control change signal to the control chip module replace the GPIO control signal when the BIOS update is completed.

Abstract: A computer memory configuration inspection method and system method and system is proposed, which is designed for use with a computer motherboard for providing a memory configuration inspection function, and which is characterized by the utilization of an embedded set of memory specification data that are factory-stored in each DIMM memory module to determine whether the actual configuration of the installation of the DIMM memory modules is correct. This feature allows the user to be unnecessary to be familiar with DIMM's technical specification and nevertheless be able to install DIMM memory modules in correct configuration on the motherboard.

Abstract: A configuration for tuning CPU working frequency and method thereof is disclosed, thereby adjusting the working frequency of a CPU of a data processing system at any time. An additional control circuit is not needed. The configuration is composed of firmware and software. When the temperature of the data processing system is too high, the working frequency of the CPU may be adjusted through the configuration and the method of the invention to lower the temperature of the CPU. Meanwhile, when the data processing system enters an idle mode, the frequency of the CPU is also lowered to reduce power consumption.
