The switch unit electrically communicates with the north bridge chipset or the digital photo frame chipset according to a triggering signal. The motherboard may utilize the stand-by power in the power-off state to display an image by a display device via the digital photo frame chipset and the north bridge chipset when a computer system is powered off.

Abstract: A motherboard capable of detecting consumed power and a method for detecting consumed power thereof are provided. The motherboard includes a VCC layer, a plurality of resistance elements, and a detecting module. A plurality of power traces are laid at the VCC layer, and each of the power traces conducts an operating voltage, respectively. The resistance elements are laid at sources of each of the power traces, respectively. The detecting module is coupled with each of the resistance elements, respectively, to obtain a current value of a current flowing through each of the resistance elements, and generates consumed power corresponding to each of the operating voltages according to the current value and the operating voltage corresponding to the current value.

Abstract: A computer system includes a clock generator, a system chipset, a controller and a multiplexing unit. The clock generator generates a reference clock according to a plurality of setting values in a frequency setting table. The system chipset generates a piece of first clock control information and a first clock. The controller is used to switch the level of the control signal and generates a piece of second clock control information and a second clock. The multiplexing unit is used to receive the control signal to select either the first clock control information or the second clock control information to be a piece of main clock control information and select either the first clock or the second clock to be a main clock. The clock generator adjusts the setting values according to the main clock control information and the main clock to change the frequency of the reference clock.

Abstract: A computer system includes a triggering device; and a motherboard, connected to the triggering device, further comprising: a memory stored with a setting parameter of a basic-input-output-system; and a counter connected between the triggering device and the memory; wherein an erasing signal, for erasing the memory, is outputted to the memory from the counter according to a triggering signal outputted from the triggering device while a boosting procedure cannot be successfully executed by the computer system.

Abstract: A power saving system is provided, comprising a system chip, at least one controller and at least one corresponding switch. The system chip is coupled to the controller. The controller is coupled between the system chip and a connector. The switch is coupled between the controller and a power and is turned on or off according to a GPIO signal. When the switch is turned on, the controller is active. When there is no device through the connector and the controller coupled to the system chip, the controller is turned off for power saving.

Abstract: A motherboard, a method for recovering a BIOS thereof, and a method for booting a computer are provided. In the method for booting the computer, a first boot block of a first BIOS unit is executed first, and then a second boot block of a second BIOS unit is executed. Afterwards, BIOS main program codes of the second BIOS unit are executed. When the second BIOS unit is down, a recovery mechanism of the first boot block is used to overwrite data in the second BIOS unit with a backup file.

Abstract: A computer has a first BIOS unit, a second BIOS unit, a bus, a detecting unit, and a first delay unit. The detecting unit is connected to the bus, the first BIOS unit, and the second BIOS unit operationally. In addition, the first delay unit is electrically connected to the detecting unit for controlling the detecting unit to check a status of a bus signal on the bus after a predetermined delay time. Accordingly, the detecting unit may enable the first BIOS unit or the second BIOS unit to boot the computer system according to the state of the bus signal.
