    Abstract: Techniques for intercommunication amongst device drivers are described herein. In one embodiment, an application programming interface (API) is provided by a kernel of an operating system (OS) running within a data processing system. The API is accessible by device drivers associated with multiple devices installed in the system. In response to a request from a first instance of a driver via the API, information indicating whether another instance of the same driver is currently started is returned via the API. Other methods and apparatuses are also described.

    Abstract: A method and an apparatus for configuring a key stored within a secure storage area (e.g., ROM) of a device including one of enabling and disabling the key according to a predetermined condition to execute a code image are described. The key may uniquely identify the device. The code image may be loaded from a provider satisfying a predetermined condition to set up at least one component of an operating environment of the device. Verification of the code image may be optional according to the configuration of the key. Secure execution of an unverified code image may be based on a configuration that disables the key.

    Abstract: A method and an apparatus for executing codes embedded inside a device to verify a code image loaded in a memory of the device are described. A code image may be executed after being verified as a trusted code image. The embedded codes may be stored in a secure ROM (read only memory) chip of the device. In one embodiment, the verification of the code image is based on a key stored within the secure ROM chip. The key may be unique to each device. Access to the key may be controlled by the associated secure ROM chip. The device may complete establishing an operating environment subsequent to executing the verified code image.

    Abstract: A method and apparatus for securely booting software components in an electronic device to establish an operating environment are described herein. According to an aspect of the invention, software components are to be executed in sequence in order to establish an operating environment of a device. For each software component, a security code is executed to authenticate and verify an executable code image associated with each software component using one or more keys embedded within a secure ROM (read-only memory) of the device and one or more hardware configuration settings of the device. The security code for each software component includes a common functionality to authenticate and verify the executable code image associated with each software component. In response to successfully authenticating and verifying the executable code image, the executable code image is then executed in a main memory of the device to launch the associated software component.
