Abstract:
A device information management system comprises an application device and a BIOS ROM. The BIOS ROM comprises at least one specific region storing device information for the application device. The specific region is not used by a BIOS and not within a calculation range for checksum calculation. The BIOS ROM further comprises an index recording an address of the specific region. The application device reads the index from the BIOS ROM, and reads the device information from the specific region according to the index.
Abstract:
A system and method for power management in computer systems. System status assessed by a Northbridge, and the result transferred to a Southbridge. A system control table is provided in the Southbridge, whereby power management without software control is provided.
Abstract:
In an electric appliance system, an electric appliance for performing designated functions and first and second remote controllers are included. The first remote controller is optionally triggered for controlling a first group of the designated functions, and the second remote controller is optionally triggered for controlling a second group of the designated functions. The second group includes at least one designated function included in the first group and at least one designated function excluded from the first group.
Abstract:
An interruption control system includes a first input/output interruption controller, a second input/output interruption controller, and an interruption control device bus. The first input/output interruption controller is coupled to a first peripheral device and a south bridge chip, and asserts a wake-up signal to the south bridge chip in response to a first interrupt signal issued by the first peripheral device so as to deactivate a power-saving state of the computer system. The second input/output interruption controller is coupled to a second peripheral device and a north bridge chip, and asserts a third interrupt signal in response to a second interrupt signal issued by the second peripheral device. Via the interruption control device bus, the third interrupt signal is transmitted from the second input/output interruption controller to the first input/output interruption controller, wherein the first input/output interruption controller asserts the wake-up signal to deactivate the power-saving state of the computer system in response to the third interrupt signal.
Abstract:
A method and a chipset for supporting a system management mode interrupt of a multi-processor system. While the central processing is accessing the specified input/output port defined by the chipset, the chipset detects the specified input/output port at the peripheral component interface bus and extracts the trap data to store into the chipset. Therefore, while entering the system management mode, a first central processing unit executes a proper operation according to the trap data of the chipset, and a second central processing unit stands by until the proper operation is completed by the first central processing unit. Thus, when the central processing units in a multi-processor system enters the system management mode, the first central processing unit can access the parameters from chipset even though the system management interrupt is induced by the second central processing unit and the parameters are stored in the second CPU's state dump area. In this way, the error, that the first central processing unit does not know which parameters stored in the first central processing unit's state dump area or the second central processing unit's state dump area should be accessed, can be completely resolved.
