  • Publication number: 20070208891
    Abstract: The present invention provides a KVM switching system including a KVM controller, a signal converter, a processor and a linking apparatus. The booting status signal of a computer is sent to the signal converter, which then converts the status signal. The converted status signal is sent to the processor, which then determines whether or not the computer is in a process of asking a user to enter BIOS setting mode. The processor automatically controls the KVM controller to issue an interruption instruction to the computer when the computer is in the process of asking a user to enter BIOS setting mode.

  • Patent number: 7263468
    Abstract: A method of storing a data access record is described. The method of storing the records employs a micro control unit (MCU) to execute the control steps of the data access records and store the records in a non-volatile random access memory (NVRAM) in the network communication device. The boot timing is written in the NVRAM while a host system starts up and is used to login one or more client computer systems. The data access records are completely written in the NVRAM of the network communication device when the client computer systems are controlled by the host computer system. Additionally, the data access records stored in the NVRAM can be exported to a network attached storage (NAS) to expand the capacity of the NVRAM when the storage capacity for the data access records runs out or backup timing is due.
