Methods and systems for managing the operation of data processing systems are disclosed. A data processing system may include a computing device that may perform various operations using hardware devices. The operation of the hardware devices may be updated by storing data in secure locations of the hardware devices. To store data in the secure locations, a delayed write may be stored in an unsecure storage location of a hardware devices during an unsecure phase of operation of a data processing system. Once the data processing system enters a more secure phase of operation, the delayed write may be validated and used to update the data in the secure locations during the more secure phase of operation of the data processing system.
