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.
