Abstract
An information handling system determines a difference between a first set of initialization information and a second set of initialization information during a pre-extensible firmware interface initialization phase of a boot process that is based on a first basic input/output system (BIOS), wherein the first set of initialization information is associated with the first BIOS and the second set of initialization information is associated with a second BIOS. The system also creates and publishes 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. The system parses 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, wherein the hand-off block is passed from the pre-extensible firmware interface initialization phase of the boot process. The system then updates the first set of initialization information based on the difference during the driver execution environment phase before continuing the boot process with the second BIOS using updated initialization information.
