An apparatus and a method for testing a sound card are applicable for detecting whether a sound leakage problem occurs to a sounding interface of the sound card. The testing apparatus includes a switching circuit and a switching unit. The switching circuit is electrically connected to the sounding interface and a sound-receiving interface of the sound card respectively, and has a plurality of transfer paths. The switching circuit is used to receive a first and a second sound channel, and to connect the first and the second sound channel to corresponding transfer paths, so as to transmit the audio signal back to the sound-receiving interface. The switching unit is electrically connected to the sounding interface and the switching circuit, for receiving the first and the second sound channel. The switching unit alters the transfer paths in the switching circuit according to a first and/or a second switching audio signal.

A data repair and synchronization method of dual flash ROM is provided, which includes a first flash ROM and a second flash ROM that store the same system data, wherein one of the first flash ROM and the second flash ROM is used to perform a data repair on the other flash ROM with damaged data and perform a data synchronization between the two flash ROMs, thereby ensuring that once the data in one flash ROM is damaged during the system operation, the complete system data stored in the other flash ROM is used to recover the damaged operating system and the files in the system. Meanwhile, through performing the data synchronization periodically, important configuration files in the system stored in the two flash ROMs are kept to be updated and completed.

A method of automatically adjusting a size of a copy-on-write (COW) disk space of a snapshot device is provided. A first disk space of a snapshot device is initialized, and a COW operation is performed on a chunk of the first disk space. Next, it is determined whether a chunk sequence number of a write request is in the first disk space. Then, if the chuck sequence number of the write request is in the first disk space, the first disk space is maintained. Then, if the chuck sequence number of the write request is not in the first disk space, a second disk space is initialized, and the number of chunks of the second disk space is the same as the number of maximum successive chunks of the first disk space, and then, the COW operation is performed on the chunk of the second disk space.

A hard disk testing method under an extensible firmware interface (EFI) is provided, which includes the following steps. A system file is backed up from the EFI of the hard disk into a storage area of a memory. The backup area of the system file is mapped as a real hard disk. A non-system file storage area is established in the memory, so as to store the non-system files of a hard disk test. Information of the system and non-system files of the hard disk test is acquired, so as to generate a system and a non-system file link table. When performing the test, the non-system files are backed up into the non-system file storage area. The system file link table and/or the non-system file link table is accessed, so as to load the system file and/or the non-system files directly from the storage area of the memory.

A peripheral component interconnect (PCI) bus test system and method therefor, that is applied in a PCI test card. The PCI test card includes a static random-access-memory (SRAM). In the method, the data transaction of the PCI bus signal is disintegrated into a separate data operation, while eliminating the waveform interfering transaction. Through comparing the waveform of the data operation as separated from a PCI bus signal with the standard PCI bus waveform, the quality of the PCI bus signals can be precisely analyzed, thus realizing the hardware test of PCI bus.

A Dead man timer detecting method, a multiprocessor switching method, and a processor hot plug support method are provided. A hot spare boot control register communicated with the Dead man timer is used to detect functions of the Dead man timer, such as enabling, timing, disabling, and responding. After an operation system is booted, the Dead man timer is used to achieve automatic switch among multiple processors and the support for the processor hot plug. The method can detect various functions of the Dead man timer, and be switched among multiple processors automatically and periodically, without being limited by the type of operation systems and processors, and realize the support to the processor hot plug, thereby improving the safety for the hot plug operation.

A sales management system and a sales management method are applied in a data processing device under a network environment to synchronously update sales information from different suppliers to a database by an information synchronization mechanism, to establish linkage between the suppliers and retailers through a supplier maintenance process, a retailer maintenance process and a supplier-retailer maintenance process in a logic control module, and to synchronize information with the retailers by the information synchronization mechanism. Therefore, only a set of client data and sales information needs to be maintained to provide sales and purchase information for a plurality of different suppliers and retailers.

A warehouse management system is applied under a network environment to integrate warehouses of suppliers and retailers in the network environment and provide an information communication channel between the suppliers and retailers. The warehouse management system includes a logic management module for allowing the suppliers and retailers to enter information; a data storage module for storing the information; an information management module for synchronously updating the information to the data storage module; and an information display module for synchronously displaying the information on data processing devices. By the warehouse management system, integration of warehouse management can be achieved, such that management efficiency and economic benefits are enhanced.

Disclosed provides a method of conducting a network virtual software game. First, a network terminal collects user's data and transfers the user's data to a server. The server verifies the user's data. The server then looks up and displays the parameter data of the online software game machine. The network terminal receives and transfers the software game parameter data set by the user to the server. According to the software game parameter data set by the user, the server then conducts a game computation process. The network terminal receives and displays in real-time the game computation process and its results thereof. Lastly, according to the results of the game computation process, the server allocates the user's data. Remote playing of the virtual software game can be thereby achieved.

A system and method uses a debug card to access to PCI bus data. The debug card includes a PCI interface, a storage module, a data control chip and a host interface. First, the PCI interface of the debug card is used to access to the PCI bus data. The accessed data are stored in a buffer of the debug card. The data control chip of the debug card then is used to control the access to the data stored in the buffer of the debug card. The accessed data are stored in a buffer of the data control chip. Lastly, the host interface of the debug card is used to output the data stored in the buffer of the data control chip.
