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.
Claims20
A method comprising:
- authorizing a computer initialization and testing code change for a computing device;
- storing a first copy of the computer initialization and testing code change in a first memory accessible by a processor;
- and
- storing a second copy of the computer initialization and testing code change in a second memory electrically isolated from the processor,
- wherein the computer initialization and testing code comprise at least one of a boot order of the computer initialization and testing, hardware configurations of the computing device, a computer initialization and testing security mechanism, and modifications thereof.
A non-transitory computer-readable storage medium comprising instructions that when executed by a processor cause a computing device to:
- initiate execution of a boot sequence for a computer initialization and testing;
- validate a computer initialization and testing code in a first memory accessible by the processor;
- and
- when the validation the computer initialization and testing code fails, obtain a backup of the computer initialization and testing code from a second memory electrically isolated from the processor for restoring the computer initialization and testing code in the first memory with the backup of the computer initialization and testing code from the second memory,
- wherein the computer initialization and testing code comprises at least one of a boot order of the computer initialization and testing, hardware configurations, and a computer initialization and testing security mechanism.
A computing device comprising:
- a processor to execute a boot sequence of a computer initialization and testing stored in a first memory for authorization of a computer initialization and testing code change, wherein the first memory is accessible by the processor to store a first copy of the computer initialization and testing code change upon authorization of the computer initialization and testing code change;
- and
- a second memory electrically isolated from the processor to store a second copy of the authorized computer initialization and testing code change,
- wherein the computer initialization and testing code comprises at least one of a boot order of the computer initialization and testing, hardware configurations, a computer initialization and testing security mechanism.
