Patent ID: 8380973

Claim:
A method for booting first and second partitions in a processing system that has multiple processing units, the method comprising: during an initialization process for the processing system: copying software to a sequestered area of memory in the processing system; configuring the processing system to hide the sequestered area of memory from a first partition of the processing system, wherein configuring the processing system comprises: generating a list of devices to be sequestered from the first partition at the first partition; starting the second partition of the processing system; and sending the list of devices to the second partition; using the software in the sequestered area of memory and a second processing unit of the processing system to boot the second partition of the processing system based on the list of devices to be sequestered; using an operating system (OS) and a first processing unit of the processing system to boot the first partition of the processing system; running a basic input/output system (BIOS) loader with a first memory map to create a first BIOS region for the first partition; and running the BIOS loader with a second memory map to create a second BIOS region for the second partition.
