Classification: CPC G | IPC G

Claim 13:
14. A non-transitory computer readable medium including code that when executed performs a method, the method comprising:
determining a difference between a first set of initialization information associated with a first basic input/output system (BIOS) and a second set of initialization information associated with a second BIOS during a pre-extensible firmware interface initialization phase of a boot process, wherein the first set of initialization information is further associated with a first BIOS reference code and the second set of initialization information is further associated with a second reference code;
creating and publishing 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;
parsing 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; and
updating the first set of initialization information based on the difference according to the second BIOS and the second reference code and if there is an additional entry in the hand-off block, then initializing the additional entry with a default value; and
taking a backup before continuing the driver execution environment phase of the boot process and updating the first BIOS and the first reference code to the second BIOS and the second reference code using updated initialization information.
