Abstract: DATA PROCESSING METHOD AND APPARATUS FOR VERIFYING ADAPTER DESCRIPTION FILE CHOICES A data processing system has a microprocessor for executing programs useful in installing adapters having programmable option select (POS) registers. An adapter description file (ADF) stores a list of possible choices which define system resources usable by the adapter. An adapter description program (ADP) verifies certain of the choices. A configuration program then selects a valid choice and stores it in a non-volatile memory from where it can be read upon subsequent system startups into the POS registers.

Abstract: A method to delivery encrypted digital content to a end user system for playing the content comprising the steps of: reading from a computer readable medium metadata which has previously associated with the content. A user selects from the metadata associated content to decrypt and the end user system establishes a secure connection with an authorisation authority for decrypt ing the content. The end user system receives a secure container containing the decrypting key for decrypting at least part of the previously encrypted content as permitted. The system creates a secure container using the encrypting key from a clearing house, wherein the secure container has an encrypting key therein from the end user system; transferring the secure container to the clearing house for authentication of permission to decrypt the content. The system receives from the clearing house, a secure container encrypted using the encrypting key of the end user system containing the decrypting key for decrypting at least part of the previously encrypted content stored on the computer readable medium as permitted; and playing at least part of the previously encrypted content by decrypting the secure container using the encrypting key of the end user system to access the decrypting key for decrypting at least part of the encrypted content.

Abstract: A data processing system (10) has a microprocessor (12) for executing programs useful in installing adapters (22) having programmable option select (POS) registers (26). An adapter description file (ADF) (39) stores a list of possible choices which define system resources usable by the adapter (22). An adapter description program (ADP) (41) verifies certain of the choices. A configuration program (35,37) then selects a valid choice and stores it in a non-volatile memory (16) from where it can be read upon subsequent system startups into the POS registers (26).
