  • Apparatus and method for converting parallel and serial PCI hot plug signals
    Patent number: 7506093
    Abstract: A method and apparatus are provided for operating a hot plug system. A first device may determine whether the system is to operate in one of a parallel mode or a serial mode. A second device may control a mode of the chipset based on the determination of the first device. The second device may include logic, a first multiplexer, a second multiplexer, a first converter and a second converter all provided on the chipset.
    Type: Grant
    Filed: March 27, 2007
    Date of Patent: March 17, 2009
    Assignee: Intel Corporation
    Inventors: Joseph A. Bennett, David Sastry

  • Deterministic shut down of memory devices in response to a system warm reset
    Patent number: 7181605
    Abstract: A method to deterministically shut down memory devices in response to a system warm reset has been disclosed. One embodiment of the method includes causing a first type of reset in a number of memory devices in a system in response to a second type of reset in the system being initiated if the memory devices are not initialized and enabling a deterministic shutdown mode in a memory controller, which is coupled to the memory devices, after the memory devices have been initialized. Other embodiments are described and claimed.
