Abstract
Initially, a hardware inventory device is provided within the data processing system. UIC that uniquely identifies the data processing system is stored in a non-erasable memory of the hardware inventory device. An encrypted hash generated by combining the UIC and a BIOS hash is stored in the non-erasable memory of the hardware inventory device. In response to a loading of a software program previously installed within a direct access storage device of the data processing system, the following steps are performed: i. the encrypted hash is obtained from the non-erasable memory of the hardware inventory device; ii. the encrypted hash is decrypted; iii. a new hash is generated by using the UIC and a BIOS from the data processing system, and the decrypted hash is compared with the new hash; and iv. the software program loading is allowed to continue when the decrypted hash matches the new hash.
