1. A computing device comprising:

  • a plurality of programmable buttons that are independent of a computer keyboard, each of said buttons being configured to generate a system control interrupt (SCJ) when actuated;

    an operating system comprising an Advanced Configuration and Power Interface (ACPI) driver capable of processing SCIs received from said programmable buttons and generating a corresponding notification;

    a button driver for processing the notification from said ACPI driver and for generating a report; and

    a button support package which implements a desired action in response to said report based on how the button has been programmed,wherein at least one of said buttons is adapted to generate a system management interrupt (SMI) while the operating system is being loaded, such that a desired action can be implemented prior to the time the ACPI driver is loaded.
