  • Patent number: 8149866
    Abstract: A system and method and method for filtering communications at a network interface controller is provided. The network interface controller is coupled to a baseboard management controller through a sideband communications channel. The network interface controller filters packets to the baseboard management controller on the basis of the address within the packet that identifies the device that caused the packet to be generated. The network interface controller transmits to the baseboard management controller only those packets that were generated in response to a command issued by the baseboard management controller.

  • Patent number: 6035346
    Abstract: By allowing a host processor to control an intelligent Peripheral Component Interface (PCI) device's reset logic, the PCI device's programmable read only memory (also known as PROM, EEPROM, or FLASH EEPROM) can be reprogrammed without storing any reprogramming instructions (also known as PROXY code) in the PROM itself. During reprogramming operations the host processor commands the PCI device into a reset-and-hold mode. During this time the host processor downloads reprogramming instructions and replacement code into the PCI's random access memory. When released from reset, the PCI device executes the reprogramming code downloaded by the host processor.
