Abstract: Examples herein disclose receiving a basic input output system (BIOS) policy change and authorizing the BIOS policy change. Upon the authorization of the BIOS policy change, a first copy of the BIOS policy is stored in a first memory accessible by a central processing unit. Additionally, a second copy of the BIOS policy change is transmitted for storage in a second memory electrically isolated from the central processing unit.

Abstract: A second physical-address-dependent code is generated from a first physical-address-dependent code using differential data, where the generating comprises converting a first physical address in a region of the first physical-address-dependent code to a second, different physical address for inclusion in a corresponding region of the second physical-address-dependent code.
