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.

According to a method for automatically unfolding a computer monitor when starting a notebook, the opening speed of the computer monitor is determined, according to a predetermined starting time needed for a computer starting program (for example, the average time needed for the operating system initialization after activating the notebook) and a predetermined opening angle of the computer monitor, after the notebook is started. Meanwhile, a shaft coupled to the computer monitor is controlled through an on-off device according to the opening speed of the computer monitor, to unfold the computer monitor to a using position. This greatly facilitates the usage of a notebook upon its starting and activating. Further, its design is more convenient.

A data manipulation method of a logical volume manager is applicable to data management of dependent snapshot volumes (SVs) of a logical volume manager. The data management method includes the following steps generating a plurality of SVs, defining the SV generated at first as a first SV, defining the SV generated at last as a last SV, and defining the rest SVs as middle SVs; selecting a middle SV; combining content stored in the selected middle SV into a neighboring SV; according to the combined SV, combining meta-data of the selected middle SV into meta-data of the middle SV; deleting the selected middle SV. The logical volume manager does not need copy the data again, thereby saving access time in data management.

A storage service device with a dual controller and a backup method thereof are applicable to provide the same view service to an event-login log and a configuration file of a server. The storage service device includes a first control module, a second control module, a battery unit, a basic input/output system (BIOS), and a backup procedure. Once a power failure occurs to the server, the following backup procedure is performed a hardware interrupt signal is sent to the battery unit, so as to provide an operation power to a first memory module and a second memory module; an index page of the first memory module is synchronized with that of the second memory module; and the updated index pages are recorded into a first flash memory and a second flash memory respectively.

A method for controlling a web page operation in browser/server architecture is adapted to prevent the same page from being operated by more than one people at the same time. The method includes establishing a status record table for recording a usage status of web page by server; checking usage status of web page in status record table after server receiving a request for operating the web page from a second browser; accepting request and submitting an operation control right of the web page to second browser if the usage status is idle; sending a check message to first browser to check whether first browser is still using the web page or not if usage status in status record table indicates that web page is used by first browser; rejecting request and transmitting usage status of web page to second browser if first browser is still using the web page.

A system and method for providing Java Server Page (JSP) security are provided. In one embodiment, a method for providing JSP security comprises selecting a JSP file at least partially in response to a request by a user. The request includes information identifying the user. A security tag associated with at least a portion of the JSP file is located for the selected JSP file. Authorization of the user to access the portion of the JSP file is determined based on the security tag. At least one web page is generated based, at least in part, on the determination.
