Abstract:
1. A method for booting a non-EFI compliant operating system in a multi-partition processing system, the method comprising: transmitting an interrupt from a second partition in the multi-partition processing system to a first partition in the multi-partition processing system; entering an interrupt handler of the first partition in response to receiving the interrupt at the first partition; after the first partition enters the interrupt handler, disabling an address line of the processing system by the second partition; calling an operating system (OS) boot loader for the second partition after transmitting the interrupt from the second partition to the first partition; after the address line has been disabled, determining, from the first partition, whether the address line has been enabled; enabling the address line by the second partition after calling the OS boot loader for the second partition and before an operating system is loaded in the second partition; and exiting the interrupt handler of the first partition only after determining that the address line has been enabled.
