Abstract
A method for recovering from software and/or hardware failures occurred in a data processing system is disclosed. A current version of boot code and an updated version of boot code are stored in a first memory region and a second memory region, respectively, of a non-volatile memory of the data processing system. The updated version of boot code is periodically replaced by a latest version of boot code downloaded from a support center. After an occurrence of a system crash, a determination is made if the system crash was caused by a known problem that can be remedied by the updated version of boot code. If so, the data processing system is rebooted using the updated version of boot code. Otherwise, data related to the system crash is collected, and the data processing system is rebooted using the current version of boot code.
