An intranet IP address modification system and method for a dual controller, and is used to modify the intranet IP addresses dynamically under the condition of keeping an intranet based TCP connection of a dual controller from disruption and disconnection. Before modifying the intranet IP address, blocking all data transmission of an intranet connection simultaneously at both ends of the intranet connection of a dual controller; next, re-determining the network card IP's at both ends of the intranet connection based on a conflicting internet IP address; then, revising the intranet IP's and routing table according to the re-determined IP address, modifying correspondingly the remote terminal IP's in an ARP buffer storage and a corresponding MAC address, and modifying correspondingly portal IP address of the intranet connection; and finally, upon the completion of intranet IP address modification, resuming data transmission of the intranet connection simultaneously at both ends of the connection.

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.
