  • Control post or joystick electromechanically engaging a keypad-centered pointer device for a laptop computer or the like
    Patent number: 6654004
    Abstract: In a laptop computer having a display, a matrix of touch-sensitive keys, and a TrackPoint® device for generating cursor and function selection on display is embedded centrally among the keys. The TrackPoint® has a removable cap into which the joystick can be mechanically and electrically coupled. This permits stable platform joystick operation, especially where the computer executes programs involving a joystick as an element of a simulated control interface.

  • Initial program load in data processing network
    Patent number: 6535976
    Abstract: Methods of booting a client data processing system attached to a control data processing system in a data processing network. At power-on or re-boot of a client system, an initial program load request is issued from the client system onto the network and responsive to the receipt of the initial program load request at the control system, bootstrap code is transferred to the client to cause the client to boot from operating system code stored on a mass storage device of the client; alternatively, bootstrap code is transferred to the client system to cause the client to boot from operating system stored on a mass storage device of the client, or bootstrap code is transferred to cause the client system to boot from the control system.
