Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. An information handling system, comprising:
a memory device; and
a processor communicatively coupled to the memory device, the processor configured to:
determine a difference between a first set of initialization information of a first basic input/output system (BIOS) and a second set of initialization information of a second BIOS during a pre-extensible firmware interface initialization phase of a boot process wherein the first set of initialization information is associated with a first reference code and the second set of initialization information is associated with a second reference code;

create and publish a hand-off block that includes an entry which describes the difference between the first set of initialization information and the second set of initialization information;
parse the hand-off block during a driver execution environment phase to determine the difference between the first set of initialization information and the second set of initialization information;
update the first set of initialization information based on the difference during the driver execution environment phase to conform with the second BIOS and the second reference code and if there is additional entry, in the hand-off block, then initialize the additional entry with default value; and
take a backup before continuing the boot process with the second BIOS using updated initialization information.
