Abstract
A method includes tagging, by a processor executing a first operating system kernel, a region of a volatile memory coupled to the processor, and initiating a boot of a second operating system kernel while preserving in the volatile memory contents stored therein. Following the boot of the second operating system kernel, a set of parameters referencing the tagged region is retrieved from the volatile memory, and the tagged region is then used, based on the retrieved set of parameters.
